Detailed Description

Class defining particle system based special effects.

Remarks: Particle systems are special effects generators which are based on a number of moving points to create the impression of things like like sparkles, smoke, blood spurts, dust etc.

: This class simply manages a single collection of particles in world space with a shared local origin for emission. The visual aspect of the particles is handled by a ParticleSystemRenderer instance.

: Particle systems are created using the SceneManager, never directly. In addition, like all subclasses of MovableObject, the ParticleSystem will only be considered for rendering once it has been attached to a SceneNode.

Member Typedef Documentation

◆ MovableObjectArray

typedef FastArray<MovableObject*> Ogre::MovableObject::MovableObjectArray

Remarks: We don't pass by reference on purpose (avoid implicit aliasing) We perform frustum culling AND test visibility mask at the same time

Parameters

frustum	Frustum to clip against
sceneVisibilityFlags	Combined scene's visibility flags (i.e. viewport \| scene). Set LAYER_SHADOW_CASTER bit if you want to exclude non-shadow casters.
outCulledObjects	Out. List of objects that are (fully or partially) inside the frustum and should be rendered

Member Function Documentation

◆ _getIterator()

ParticleIterator Ogre::ParticleSystem::_getIterator ( void )

Returns an iterator for stepping through all particles in this system.

Remarks: This method is designed to be used by people providing new ParticleAffector subclasses, this is the easiest way to step through all the particles in a system and apply the changes the affector wants to make.

◆ _getLightList()

LightList * Ogre::MovableObject::_getLightList ( )

inlineinherited

Returns a pointer to the current list of lights for this object.

Remarks: You should not modify this list outside of MovableObject::Listener::objectQueryLights (say if you want to use it to implement this method, and use the pointer as a return value) and for reading it's only accurate as at the last frame.

inlinevirtualinherited

Called by SceneManager when it is telling we're a static MovableObject being dirty Don't call this directly.

See also: SceneManager::notifyStaticDirty

Reimplemented in Ogre::v1::InstancedEntity.

◆ _releaseManualHardwareResources()

virtual void Ogre::MovableObject::_releaseManualHardwareResources ( )

inlinevirtualinherited

Notifies the movable object that hardware resources were lost.

Remarks: Called automatically by RenderSystem if hardware resources were lost and can not be restored using some internal mechanism. Among affected resources are nested shadow renderables, ManualObjects, etc.

Reimplemented in Ogre::v1::BillboardSet, and Ogre::v1::ManualObject.

◆ _restoreManualHardwareResources()

virtual void Ogre::MovableObject::_restoreManualHardwareResources ( )

Remarks: Called automatically by RenderSystem if hardware resources were lost and can not be restored using some internal mechanism. Among affected resources are nested shadow renderables, ManualObjects, etc.

◆ _update()

void Ogre::ParticleSystem::_update ( Real timeElapsed )

Updates the particles in the system based on time elapsed.

Remarks: This is called automatically every frame by OGRE.

Parameters

timeElapsed The amount of time, in seconds, since the last frame.

◆ _updateBounds()

void Ogre::ParticleSystem::_updateBounds ( void )

Internal method for updating the bounds of the particle system.

Remarks: This is called automatically for a period of time after the system's creation (10 seconds by default, settable by setBoundsAutoUpdated) to increase (and only increase) the bounds of the system according to the emitted and affected particles. After this period, the system is assumed to achieved its maximum size, and the bounds are no longer computed for efficiency. You can tweak the behaviour by either setting the bounds manually (setBounds, preferred), or changing the time over which the bounds are updated (performance cost). You can also call this method manually if you need to update the bounds on an ad-hoc basis.

◆ _updateRenderQueue()

virtual void Ogre::ParticleSystem::_updateRenderQueue	(	RenderQueue *	queue,
		Camera *	camera,
		const Camera *	lodCamera

Remarks: Particles are modified over time in a particle system by affectors - see the ParticleAffector class for more details.

Parameters

affectorType String identifying the affector type to create. Affector types are defined by registering new factories with the manager - see ParticleAffectorFactory for more details. Affector types can be extended by OGRE, plugin authors or application developers.

◆ addEmitter()

		ObjectData	t,
		const LightListInfo &	globalLightList
	)

staticinherited

@See SceneManager::buildLightList

	)

staticinherited

◆ cleanupDictionary()

static void Ogre::StringInterface::cleanupDictionary ( )

staticinherited

MaterialManager) initializes.

◆ clear()

void Ogre::ParticleSystem::clear ( )

Empties this set of all particles.

◆ copyParametersTo()

virtual void Ogre::StringInterface::copyParametersTo ( StringInterface * dest ) const

inlinevirtualinherited

Method for copying this object's parameters to another object.

Remarks: This method takes the values of all the object's parameters and tries to set the same values on the destination object. This provides a completely type independent way to copy parameters to other objects. Note that because of the String manipulation involved, this should not be regarded as an efficient process and should be saved for times outside of the rendering loop.

: Any unrecognised parameters will be ignored as with setParameter method.

Parameters

dest	Pointer to object to have it's parameters set the same as this object.

◆ createAnimableValue()

virtual AnimableValuePtr Ogre::AnimableObject::createAnimableValue ( const String & valueName )

inlinevirtualinherited

Create a reference-counted AnimableValuePtr for the named value.

Remarks: You can use the returned object to animate a value on this object, using AnimationTrack. Subclasses must override this if they wish to support animation of their values.

Reimplemented in Ogre::Light.

References Ogre::Exception::ERR_ITEM_NOT_FOUND, and OGRE_EXCEPT.

◆ createEmitterParticle()

Particle * Ogre::ParticleSystem::createEmitterParticle ( const String & emitterName )

Manually add an emitter particle to the system.

Remarks: The purpose of a particle emitter is to emit particles. Besides visual particles, also other other particle types can be emitted, other emitters for example. The emitted emitters have a double role; they behave as particles and can be influenced by affectors, but they are still emitters and capable to emit other particles (or emitters). It is possible to create a chain of emitters - emitters emitting other emitters, which also emit emitters.

Parameters

emitterName The name of a particle emitter that must be emitted.

◆ createParticle()

Particle * Ogre::ParticleSystem::createParticle ( void )

Manually add a particle to the system.

Remarks: Instead of using an emitter, you can manually add a particle to the system. You must initialise the returned particle instance immediately with the 'emission' state.

Note: There is no corresponding 'destroyParticle' method - if you want to dispose of a particle manually (say, if you've used setSpeedFactor(0) to make particles live forever) you should use getParticle() and modify it's timeToLive to zero, meaning that it will get cleaned up in the next update.

◆ cullFrustum()

static void Ogre::MovableObject::cullFrustum	(	const size_t	numNodes,
		ObjectData	t,
		const Camera *	frustum,
		uint32	sceneVisibilityFlags,
		MovableObjectArray &	outCulledObjects,
		const Camera *	lodCamera
	)

		ObjectData	t,
		LightListInfo &	outGlobalLightList,
		const FrustumVec &	frustums,
		const FrustumVec &	cubemapFrustums
	)

staticinherited

@See SceneManager::cullLights &

See also: MovableObject::cullFrustum Produces the global list of visible lights that is needed in buildLightList

Remarks: We don't pass ObjectData by reference on purpose (avoid implicit aliasing) It's declared here because all affected elements are from MovableObject IMPORTANT: It is assumed that all objects in ObjectData are Lights.

Parameters

outGlobalLightList	Output, a list of lights, contiguously placed
frustums	An array of all frustums we need to check against
cubemapFrustums	An array of all frustums that are used at least once as cubemaps (@See SceneManager::createCamera)

◆ detachFromParent()

void Ogre::MovableObject::detachFromParent ( void )

inherited

Detaches an object from a parent SceneNode if attached.

◆ fastForward()

void Ogre::ParticleSystem::fastForward	(	Real	time,
		Real	interval = `0.1`
	)

Fast-forwards this system by the required number of seconds.

Remarks: This method allows you to fast-forward a system so that it effectively looks like it has already been running for the time you specify. This is useful to avoid the 'startup sequence' of a system, when you want the system to be fully populated right from the start.

◆ removeAffector()

void Ogre::ParticleSystem::removeAffector ( unsigned short index )

Removes an affector from the system.

Remarks: Drops the affector with the index specified from this system. You should check how many affectors are registered against this system before calling this method with an arbitrary index using getNumAffectors.

Parameters

index Zero-based index of the affector to retrieve.

Removes all the affectors from this system.

◆ removeAllEmitters()

◆ removeEmitter() [2/2]

void Ogre::ParticleSystem::removeEmitter ( unsigned short index )

Removes an emitter from the system.

Remarks: Drops the emitter with the index specified from this system. You should check how many emitters are registered against this system before calling this method with an arbitrary index using getNumEmitters.

Parameters

index Zero-based index of the emitter to retrieve.

◆ removeQueryFlags()

void Ogre::MovableObject::removeQueryFlags ( uint32 flags )

inlineinherited

As setQueryFlags, except the flags passed as parameters are removed from the existing flags on this object.

◆ removeVisibilityFlags()

void Ogre::MovableObject::removeVisibilityFlags ( uint32 flags )

inlineinherited

As setVisibilityFlags, except the flags passed as parameters are removed from the existing flags on this object.

◆ setBoundsAutoUpdated()

void Ogre::ParticleSystem::setBoundsAutoUpdated	(	bool	autoUpdate,
		Real	stopIn = `0.0f`
	)

Sets whether the bounds will be automatically updated for the life of the particle system.

Remarks: If you have a stationary particle system, it would be a good idea to call this method and set the value to 'false', since the maximum bounds of the particle system will eventually be static. If you do this, you can either set the bounds manually using the setBounds() method, or set the second parameter of this method to a positive number of seconds, so that the bounds are calculated for a few seconds and then frozen.

Parameters

autoUpdate	If true (the default), the particle system will update it's bounds every frame. If false, the bounds update will cease after the 'stopIn' number of seconds have passed.
stopIn	Only applicable if the first parameter is true, this is the number of seconds after which the automatic update will cease.

◆ setCastShadows()

void Ogre::MovableObject::setCastShadows ( bool enabled )

inlineinherited

Sets whether or not this object will cast shadows.

Remarks: This setting simply allows you to turn on/off shadows for a given object. An object will not cast shadows unless the scene supports it in any case (see SceneManager::setShadowTechnique), and also the material which is in use must also have shadow casting enabled. By default all entities cast shadows. If, however, for some reason you wish to disable this for a single object then you can do so using this method.

Note: This method normally refers to objects which block the light, but since Light is also a subclass of MovableObject, in that context it means whether the light causes shadows itself.

◆ setCullIndividually()

virtual void Ogre::ParticleSystem::setCullIndividually ( bool cullIndividual )

virtual

Sets whether culling tests particles in this individually as well as in a group.

Remarks: Particle sets are always culled as a whole group, based on a bounding box which encloses all particles in the set. For fairly localised sets, this is enough. However, you can optionally tell the set to also cull individual particles in the set, i.e. to test each individual particle before rendering. The default is not to do this.

: This is useful when you have a large, fairly distributed set of particles, like maybe trees on a landscape. You probably still want to group them into more than one set (maybe one set per section of landscape), which will be culled coarsely, but you also want to cull the particles individually because they are spread out. Whilst you could have lots of single-tree sets which are culled separately, this would be inefficient to render because each tree would be issued as it's own rendering operation.

: By calling this method with a parameter of true, you can have large particle sets which are spaced out and so get the benefit of batch rendering and coarse culling, but also have fine-grained culling so unnecessary rendering is avoided.

Parameters

cullIndividual If true, each particle is tested before being sent to the pipeline as well as the whole set having to pass the coarse group bounding test.

◆ setDefaultDimensions()

virtual void Ogre::ParticleSystem::setDefaultDimensions	(	Real	width,
		Real	height
	)

virtual

Sets the default dimensions of the particles in this set.

Remarks: All particles in a set are created with these default dimensions. The set will render most efficiently if all the particles in the set are the default size. It is possible to alter the size of individual particles at the expense of extra calculation. See the Particle class for more info.

Parameters

width	The new default width for the particles in this set. Must be non-negative!
height	The new default height for the particles in this set. Must be non-negative!

◆ setDefaultHeight()

virtual void Ogre::ParticleSystem::setDefaultHeight ( Real height )

virtual

See setDefaultDimensions - this sets 1 component individually.

◆ setDefaultIterationInterval()

static void Ogre::ParticleSystem::setDefaultIterationInterval ( Real iterationInterval )

inlinestatic

Set the default iteration interval for all ParticleSystem instances.

◆ setDefaultNonVisibleUpdateTimeout()

static void Ogre::ParticleSystem::setDefaultNonVisibleUpdateTimeout ( Real timeout )

inlinestatic

◆ setDefaultQueryFlags()

static void Ogre::MovableObject::setDefaultQueryFlags ( uint32 flags )

inlinestaticinherited

static void Ogre::MovableObject::setDefaultVisibilityFlags ( uint32 flags )

inlinestaticinherited

◆ setDefaultWidth()

virtual void Ogre::ParticleSystem::setDefaultWidth ( Real width )

virtual

See setDefaultDimensions - this sets 1 component individually.

◆ setEmittedEmitterQuota()

void Ogre::ParticleSystem::setEmittedEmitterQuota ( size_t quota )

Sets the maximum number of emitted emitters this system is allowed to have active at once.

Remarks: Particle systems can have - besides a particle quota - also an emitted emitter quota.

Parameters

quota The maximum number of emitted emitters this system is allowed to have.

◆ setEmitting()

void Ogre::ParticleSystem::setEmitting ( bool v )

This is used to turn on or off particle emission for this system.

Remarks: By default particle system is always emitting particles (if a emitters exists) and this can be used to stop the emission for all emitters. To turn it on again, call it passing true.

Note that this does not detach the particle system from the scene node, it will still use some CPU.

◆ setIterationInterval()

void Ogre::ParticleSystem::setIterationInterval ( Real iterationInterval )

Sets a 'iteration interval' on this particle system.

Remarks: The default Particle system update interval, based on elapsed frame time, will cause different behavior between low frame-rate and high frame-rate. By using this option, you can make the particle system update at a fixed interval, keeping the behavior the same no matter what frame-rate is.

: When iteration interval is set to zero, it means the update occurs based on an elapsed frame time, otherwise each iteration will take place at the given interval, repeating until it has used up all the elapsed frame time.

Parameters

iterationInterval The iteration interval, default to zero.

◆ setKeepParticlesInLocalSpace()

void Ogre::ParticleSystem::setKeepParticlesInLocalSpace ( bool keepLocal )

Sets whether particles (and any affector effects) remain relative to the node the particle system is attached to.

Remarks: By default particles are in world space once emitted, so they are not affected by movement in the parent node of the particle system. This makes the most sense when dealing with completely independent particles, but if you want to constrain them to follow local motion too, you can set this to true.

◆ setLightMask()

void Ogre::MovableObject::setLightMask ( uint32 lightMask )

inlineinherited

Set a bitwise mask which will filter the lights affecting this object.

Remarks: This mask will be compared against the mask held against Light to determine if a light should affect a given object. By default, this mask is fully set meaning all lights will affect this object

◆ setListener()

void Ogre::MovableObject::setListener ( Listener * listener )

inlineinherited

Sets a listener for this object.

Remarks: Note for size and performance reasons only one listener per object is allowed.

◆ setLocalAabb()

inherited

Sets the local axis-aligned bounding box for this object.

Remarks: This bounding box is in local coordinates.

Parameters

name	The new name of the material to use for this set.

◆ setName()

void Ogre::MovableObject::setName ( const String & name )

inlineinherited

Doesn't have to be unique

◆ setNonVisibleUpdateTimeout()

void Ogre::ParticleSystem::setNonVisibleUpdateTimeout ( Real timeout )

Sets when the particle system should stop updating after it hasn't been visible for a while.

Remarks: By default, visible particle systems update all the time, even when not in view. This means that they are guaranteed to be consistent when they do enter view. However, this comes at a cost, updating particle systems can be expensive, especially if they are perpetual.

: This option lets you set a 'timeout' on the particle system, so that if it isn't visible for this amount of time, it will stop updating until it is next visible.

Parameters

timeout The time after which the particle system will be disabled if it is no longer visible. 0 to disable the timeout and always update.

◆ setParameter()

virtual bool Ogre::StringInterface::setParameter	(	const String &	name,
		const String &	value
	)

virtualinherited

Generic parameter setting method.

Remarks: Call this method with the name of a parameter and a string version of the value to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters

name	The name of the parameter to set
value	String value. Must be in the right format for the type specified in the parameter definition. See the StringConverter class for more information.

Returns: true if set was successful, false otherwise (NB no exceptions thrown - tolerant method)

◆ setParameterList()

virtual void Ogre::StringInterface::setParameterList ( const NameValuePairList & paramList )

virtualinherited

Generic multiple parameter setting method.

Remarks: Call this method with a list of name / value pairs to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters

paramList Name/value pair list

◆ setParticleQuota()

void Ogre::ParticleSystem::setParticleQuota ( size_t quota )

Sets the maximum number of particles this system is allowed to have active at once.

Remarks: Particle systems all have a particle quota, i.e. a maximum number of particles they are allowed to have active at a time. This allows the application to set a keep particle systems under control should they be affected by complex parameters which alter their emission rates etc. If a particle system reaches it's particle quota, none of the emitters will be able to emit any more particles. As existing particles die, the spare capacity will be allocated equally across all emitters to be as consistent to the original particle system style as possible. The quota can be increased but not decreased after the system has been created.

Parameters

quota The maximum number of particles this system is allowed to have.

◆ setQueryFlags()

void Ogre::MovableObject::setQueryFlags ( uint32 flags )

inlineinherited

Sets the query flags for this object.

Remarks: When performing a scene query, this object will be included or excluded according to flags on the object and flags on the query. This is a bitwise value, so only when a bit on these flags is set, will it be included in a query asking for that flag. The meaning of the bits is application-specific.

◆ setRenderer()

void Ogre::ParticleSystem::setRenderer ( const String & typeName )

Sets the ParticleRenderer to be used to render this particle system.

Remarks: The main ParticleSystem just manages the creation and movement of particles; they are rendered using functions in ParticleRenderer and the ParticleVisual instances they create.

Parameters

typeName String identifying the type of renderer to use; a new instance of this type will be created; a factory must have been registered with ParticleSystemManager.

◆ setRenderingDistance()

void Ogre::MovableObject::setRenderingDistance ( Real dist )

inlineinherited

Sets the distance at which the object is no longer rendered.

Parameters

dist	Distance beyond which the object will not be rendered (the default is FLT_MAX, which means objects are always rendered). Values equal or below zero will be ignored, and cause an assertion in debug mode.

◆ setRenderingMinPixelSize()

void Ogre::MovableObject::setRenderingMinPixelSize ( Real pixelSize )

inlineinherited

Sets the minimum pixel size an object needs to be in both screen axes in order to be rendered.

Note: Camera::setUseMinPixelSize() needs to be called for this parameter to be used.

Parameters

pixelSize Number of minimum pixels (the default is 0, which means objects are always rendered).

◆ setRenderQueueGroup()

void Ogre::ParticleSystem::setRenderQueueGroup ( uint8 queueID )

virtual

Sets the render queue group this entity will be rendered through.

Remarks: Render queues are grouped to allow you to more tightly control the ordering of rendered objects. If you do not call this method, all Entity objects default to the default queue (RenderQueue::getDefaultQueueGroup), which is fine for most objects. You may want to alter this if you want this entity to always appear in front of other objects, e.g. for a 3D menu system or such.

: See RenderQueue for more details.

Parameters

queueID Enumerated value of the queue group to use. See the enum RenderQueueGroupID for what kind of values can be used here.

: Valid render queue ids are between 0 & 254 inclusive

Reimplemented from Ogre::MovableObject.

Parameters

dist	Distance beyond which the object will not cast shadows (the default is FLT_MAX, which means objects are always casting shadows). Values equal or below zero will be ignored, and cause an assertion in debug mode.

Note: ShadowRenderingDistance will be clamped to RenderingDistance value

See also: setRenderingDistance

◆ setSortingEnabled()

void Ogre::ParticleSystem::setSortingEnabled ( bool enabled )

inline

Set whether or not particles are sorted according to the camera.

Remarks: Enabling sorting alters the order particles are sent to the renderer. When enabled, particles are sent to the renderer in order of furthest distance from the camera.

◆ setSpeedFactor()

void Ogre::ParticleSystem::setSpeedFactor ( Real speedFactor )

inline

Sets a 'speed factor' on this particle system, which means it scales the elapsed real time which has passed by this factor before passing it to the emitters, affectors, and the particle life calculation.

Remarks: An interesting side effect - if you want to create a completely manual particle system where you control the emission and life of particles yourself, you can set the speed factor to 0.0f, thus disabling normal particle emission, alteration, and death.

◆ setStatic()

bool Ogre::MovableObject::setStatic ( bool bStatic )

inherited

Turns this Node into static or dynamic.

Remarks: Switching between dynamic and static has some overhead and forces to update all static scene when converted to static. So don't do it frequently. Static objects are not updated every frame, only when requested explicitly. Use this feature if you plan to have this object unaltered for a very long times

: Note all MovableObjects support switching between static & dynamic after they have been created (eg. InstancedEntity)

: Changing this attribute will cause to switch the attribute to our parent node, and as a result, all of its other attached entities. @See Node::setStatic

Returns: True if setStatic made an actual change. False otherwise. Can fail because the object was already static/dynamic, or because switching is not supported

◆ setVisibilityFlags()

void Ogre::MovableObject::setVisibilityFlags ( uint32 flags )

inlineinherited

Sets the visibility flags for this object.

Remarks: As well as a simple true/false value for visibility (as seen in setVisible), you can also set visibility flags that is applied a binary 'and' with the SceneManager's mask and a compositor node pass. To exclude particular objects from rendering. Changes to reserved visibility flags are ignored (won't take effect).

◆ setVisible()

void Ogre::MovableObject::setVisible ( bool visible )

inlineinherited

Tells this object whether to be visible or not, if it has a renderable component.

Note: An alternative approach of making an object invisible is to detach it from it's SceneNode, or to remove the SceneNode entirely. Detaching a node means that structurally the scene graph changes. Once this change has taken place, the objects / nodes that have been removed have less overhead to the visibility detection pass than simply making the object invisible, so if you do this and leave the objects out of the tree for a long time, it's faster. However, the act of detaching / reattaching nodes is in itself more expensive than setting an object visibility flag, since in the latter case structural changes are not made. Therefore, small or frequent visibility changes are best done using this method; large or more longer term changes are best done by detaching.

◆ updateAllBounds()

static void Ogre::MovableObject::updateAllBounds	(	const size_t	numNodes,
		ObjectData	t
	)

staticinherited

@See SceneManager::updateAllBounds

Remarks: We don't pass by reference on purpose (avoid implicit aliasing)
