Detailed Description

A ParticleSystemDef does not form part of the scene.

The reason it derives from ParticleSystem (& hence MovableObject) is to keep backwards compatibility with the interface of the older ParticleFX plugin for much easier migration/porting.

Do NOT attach it to a SceneNode.

For performance reasons, all particle system instances share the same RenderQueue ID. ParticleSystemDef must be cloned to use instances on another ID.

Clones this ParticleSystemDef with a new name into a new ParticleSystemManager2.

Spawned particle instances are not cloned.

This is useful if you need a different material or need to alter a few settings.

Remarks: This function can throw.

Parameters

◆ getNumEmitters()

size_t Ogre::ParticleSystemDef::getNumEmitters ( ) const

◆ getNumSimdActiveParticles()

size_t Ogre::ParticleSystemDef::getNumSimdActiveParticles ( ) const

inline

Returns the number of active particles rounded up to match up SIMD processing.

e.g.

ARRAY_PACKED_REALS = 4
mFirstParticleIdx = 3
mLastParticleIdx = 6
Num Active Particles = mLastParticleIdx - mFirstParticleIdx = 3
Therefore getActiveParticlesPackOffset() = 0

However we must process: 0. inactive

inactive
inactive
active
inactive
active
inactive
inactive

That means the following code:

mParticleCpuData.advancePack( getActiveParticlesPackOffset() );
for( i = 0; i < getNumSimdActiveParticles(); i += ARRAY_PACKED_REALS )
    mParticleCpuData.advancePack();

Must iterate 2 times. However if getNumSimdActiveParticles() returns 3 (3 = 5 - 3 + 1), it will only iterate once. Rounding 3 up to ARRAY_PACKED_REALS is also no good, because if it returns 4, it still iterates once.

It must return 8 (ARRAY_PACKED_REALS * 2).

Note that there can be a lot of inactive particles between mFirstParticleIdx & mLastParticleIdx. However this should be rare since particle FXs tend to follow FIFO.

◆ getParticleCpuData()

ParticleCpuData Ogre::ParticleSystemDef::getParticleCpuData ( ) const

inline

◆ getParticlesToRenderTighter()

size_t Ogre::ParticleSystemDef::getParticlesToRenderTighter ( ) const

inline

Like getNumSimdActiveParticles(), we have to consider SIMD.

However given the same example we only need to return 6, not 8.

There's not much we can do about the waste at the beginning (in a API-compatible way), but we can do something about the last 2 vertices that are waste.

This function is called "tighter" because it returns 6 instead of 8, but it is not fully "tight" because if that were the case, we'd return 3.

Used by ParticleSystemDef to indicate Hlms they want specific shader code.

◆ getRenderOperation()

void Ogre::ParticleSystemDef::getRenderOperation	(	v1::RenderOperation &	op,
		bool	casterPass
	)

overridevirtual

Gets the render operation required to send this object to the frame buffer.

Implements Ogre::Renderable.

◆ getRotationType()

ParticleRotationType::ParticleRotationType Ogre::ParticleSystemDef::getRotationType ( ) const

◆ getUseIdentityWorldMatrix()

bool Ogre::ParticleSystemDef::getUseIdentityWorldMatrix ( ) const

inlineoverridevirtual

Returns whether the world matrix is an identity matrix.

Remarks: It is up to the Hlms implementation whether to honour this request. Take in mind changes of this value at runtime may not be seen until the datablock is flushed. It is implemented as a virtual call because this functionality isn't required very often (hence we save per-Renderable space for those that don't use it) and this function will be called at creation time to use a different shader; not during rendering time per Renderable.

Reimplemented from Ogre::Renderable.

◆ getWorldTransforms()

void Ogre::ParticleSystemDef::getWorldTransforms ( Matrix4 * xform ) const

overridevirtual

Gets the world transform matrix / matrices for this renderable object.

Remarks: If the object has any derived transforms, these are expected to be up to date as long as all the SceneNode structures have been updated before this is called.

: This method will populate transform with 1 matrix if it does not use vertex blending. If it does use vertex blending it will fill the passed in pointer with an array of matrices, the length being the value returned from getNumWorldTransforms.

Note: Internal Ogre never supports non-affine matrix for world transform matrix/matrices, the behavior is undefined if returns non-affine matrix here.

See also: Matrix4::isAffine.

Implements Ogre::Renderable.

◆ init()

void Ogre::ParticleSystemDef::init ( VaoManager * vaoManager )

◆ isInitialized()

bool Ogre::ParticleSystemDef::isInitialized ( ) const

◆ reserveNumAffectors()

void Ogre::ParticleSystemDef::reserveNumAffectors ( size_t numAffectors )

If you know in advance how many times you will call addAffector() call this function to achieve optimum memory use.

This is the same as std::vector::reserve. Optional.

Parameters

numAffectors Number of times you intend to call addAffector().

◆ reserveNumEmitters()

void Ogre::ParticleSystemDef::reserveNumEmitters ( size_t numEmitters )

If you know in advance how many times you will call addEmitter() call this function to achieve optimum memory use.

This is the same as std::vector::reserve. Optional.

Parameters

numEmitters Number of times you intend to call addEmitter().

◆ setCommonDirection()

void Ogre::ParticleSystemDef::setCommonDirection ( const Vector3 & vec )

Use this to specify the common direction given to particles when type is ParticleType::OrientedCommon and ParticleType::PerpendicularCommon.

Remarks: Use ParticleType::OrientedCommon when you want oriented particles but you know they are always going to be oriented the same way (e.g. rain in calm weather). It is faster for the system to calculate the billboard vertices if they have a common direction.

If you need to call both setCommonDirection() and setCommonUpVector() often, prefer using setCommonVectors().

Parameters

vec	The direction for all particles.

◆ setCommonUpVector()

void Ogre::ParticleSystemDef::setCommonUpVector ( const Vector3 & vec )

Use this to specify the common up-vector given to billboards of type ParticleType::PerpendicularCommon and ParticleType::PerpendicularSelf.

Remarks: Use ParticleType::PerpendicularSelf when you want oriented particles perpendicular to their own direction vector and don't face to camera. In this case, we need an additional vector to determine the billboard X, Y axis. The generated X axis perpendicular to both the own direction and up-vector, the Y axis will coplanar with both own direction and up-vector, and perpendicular to own direction.

If you need to call both setCommonDirection() and setCommonUpVector() often, prefer using setCommonVectors().

Parameters

vec	The up-vector for all particles.

◆ setCommonVectors()

void Ogre::ParticleSystemDef::setCommonVectors	(	const Vector3 &	commonDir,
		const Vector3 &	commonUp
	)

See setCommonDirection() and setCommonUpVector().

Use this version if you have to often change both of these at the same time.

◆ setParticleQuota()

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

overridevirtual

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.

Reimplemented from Ogre::ParticleSystem.

◆ setParticleType()

void Ogre::ParticleSystemDef::setParticleType ( ParticleType::ParticleType particleType )

◆ setRotationType()

void Ogre::ParticleSystemDef::setRotationType ( ParticleRotationType::ParticleRotationType rotationType )
