Detailed Description

Class providing a much simplified interface to generating manual objects with custom geometry.

Building one-off geometry objects manually usually requires getting down and dirty with the vertex buffer and vertex declaration API, which some people find a steep learning curve. This class gives you a simpler interface specifically for the purpose of building a 3D object simply and quickly. Note that if you intend to instance your object you will still need to become familiar with the Mesh class.

This class draws heavily on the interface for OpenGL immediate-mode (glBegin, glVertex, glNormal etc), since this is generally well-liked by people. There are a couple of differences in the results though - internally this class still builds hardware buffers which can be re-used, so you can render the resulting object multiple times without re-issuing all the same commands again. Secondly, the rendering is not immediate, it is still queued just like all OGRE objects. This makes this object more efficient than the equivalent GL immediate-mode commands, so it's feasible to use it for large objects if you really want to.

To construct some geometry with this object:

  1. If you know roughly how many vertices (and indices, if you use them) you're going to submit, call estimateVertexCount() and estimateIndexCount(). This is not essential but will make the process more efficient by saving memory reallocations.
  2. Call begin() to begin entering data
  3. For each vertex, call position(), normal(), textureCoord(), colour() to define your vertex data. Note that each time you call position() you start a new vertex. Note that the first vertex defines the components of the vertex - you can't add more after that. For example if you didn't call normal() in the first vertex, you cannot call it in any others. You ought to call the same combination of methods per vertex.
  4. If you want to define triangles (or lines/points) by indexing into the vertex list, you can call index() as many times as you need to define them. If you don't do this, the class will assume you want triangles drawn directly as defined by the vertex list, i.e. non-indexed geometry. Note that stencil shadows are only supported on indexed geometry, and that indexed geometry is a little faster; so you should try to use it.
  5. Call end() to finish entering data.
  6. Optionally repeat the begin-end cycle if you want more geometry using different rendering operation types, or different materials After calling end(), the class will organise the data for that section internally and make it ready to render with. Like any other MovableObject you should attach the object to a SceneNode to make it visible. Other aspects like the relative render order can be controlled using standard MovableObject methods like setRenderQueueGroup.

You can also use beginUpdate() to alter the geometry later on if you wish. If you do this, you should call setDynamic(true) before your first call to begin(), and also consider using estimateVertexCount() / estimateIndexCount() if your geometry is going to be growing, to avoid buffer recreation during growth.

Note
like all OGRE geometry, triangles should be specified in anti-clockwise winding order (whether you're doing it with just vertices, or using indexes too). That is to say that the front of the face is the one where the vertices are listed in anti-clockwise order.

Member Function Documentation

◆ _releaseManualHardwareResources()

void Ogre::ManualObject::_releaseManualHardwareResources ( )
inlinevirtual

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 from Ogre::MovableObject.

References Ogre::ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME, and Ogre::RenderOperation::OT_TRIANGLE_LIST.

◆ clear()

virtual void Ogre::ManualObject::clear ( void  )
virtual

Completely clear the contents of the object.

Remarks
Clearing the contents of this object and rebuilding from scratch is not the optimal way to manage dynamic vertex data, since the buffers are recreated. If you want to keep the same structure but update the content within that structure, use beginUpdate() instead of clear() begin(). However if you do want to modify the structure from time to time you can do so by clearing and re-specifying the data.

◆ estimateVertexCount()

virtual void Ogre::ManualObject::estimateVertexCount ( size_t  vcount)
virtual

Estimate the number of vertices ahead of time.

Remarks
Calling this helps to avoid memory reallocation when you define vertices. Also very handy when using beginUpdate() to manage dynamic data - you can make the vertex buffers a little larger than their initial needs to allow for growth later with this method.

◆ estimateIndexCount()

virtual void Ogre::ManualObject::estimateIndexCount ( size_t  icount)
virtual

Estimate the number of indices ahead of time.

Remarks
Calling this helps to avoid memory reallocation when you define indices. Also very handy when using beginUpdate() to manage dynamic data - you can make the index buffer a little larger than the initial need to allow for growth later with this method.

◆ begin() [1/2]

virtual void Ogre::ManualObject::begin ( const String materialName,
RenderOperation::OperationType  opType = RenderOperation::OT_TRIANGLE_LIST,
const String groupName = ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME 
)
virtual

Start defining a part of the object.

Remarks
Each time you call this method, you start a new section of the object with its own material and potentially its own type of rendering operation (triangles, points or lines for example).
Parameters
materialNameThe name of the material to render this part of the object with.
opTypeThe type of operation to use to render.
groupNameThe resource group of the material to render this part of the object with.

◆ begin() [2/2]

virtual void Ogre::ManualObject::begin ( const MaterialPtr mat,
RenderOperation::OperationType  opType = RenderOperation::OT_TRIANGLE_LIST 
)
virtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters
matThe material to render this part of the object with.
opTypeThe type of operation to use to render.

◆ setDynamic()

virtual void Ogre::ManualObject::setDynamic ( bool  dyn)
inlinevirtual

Use before defining geometry to indicate that you intend to update the geometry regularly and want the internal structure to reflect that.

◆ getDynamic()

virtual bool Ogre::ManualObject::getDynamic ( ) const
inlinevirtual

Gets whether this object is marked as dynamic.

References Ogre::ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME.

◆ beginUpdate()

virtual void Ogre::ManualObject::beginUpdate ( size_t  sectionIndex)
virtual

Start the definition of an update to a part of the object.

Remarks
Using this method, you can update an existing section of the object efficiently. You do not have the option of changing the operation type obviously, since it must match the one that was used before.
Note
If your sections are changing size, particularly growing, use estimateVertexCount and estimateIndexCount to pre-size the buffers a little larger than the initial needs to avoid buffer reconstruction.
Parameters
sectionIndexThe index of the section you want to update. The first call to begin() would have created section 0, the second section 1, etc.

◆ position() [1/2]

virtual void Ogre::ManualObject::position ( const Vector3 pos)
virtual

Add a vertex position, starting a new vertex at the same time.

Remarks
A vertex position is slightly special among the other vertex data methods like normal() and textureCoord(), since calling it indicates the start of a new vertex. All other vertex data methods you call after this are assumed to be adding more information (like normals or texture coordinates) to the last vertex started with position().

virtual void Ogre::ManualObject::position ( float  x,
float  y,

◆ setMaterialName()

virtual void Ogre::ManualObject::setMaterialName ( size_t  subIndex,
const String name,
const String group = ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME 
)
virtual

Alter the material for a subsection of this object after it has been specified.

Remarks

Parameters
subIndexThe index of the subsection to alter
nameThe name of the new material to use
groupThe resource group of the new material to use

◆ convertToMesh()

virtual MeshPtr Ogre::ManualObject::convertToMesh ( const String meshName,
const String groupName = ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME 
)
virtual

Convert this object to a Mesh.

Remarks
After you've finished building this object, you may convert it to a Mesh if you want in order to be able to create many instances of it in the world (via Entity).

Remarks
Usually ManualObjects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normally you don't need to change this. The default is false.

◆ getUseIdentityProjection()

bool Ogre::ManualObject::getUseIdentityProjection ( void  ) const
inline

Returns whether or not to use an 'identity' projection.

Remarks
Usually ManualObjects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normally you don't need to change this.

◆ setUseIdentityView()

void Ogre::ManualObject::setUseIdentityView ( bool  useIdentityView)

Sets whether or not to use an 'identity' view.

Remarks
Usually ManualObjects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering. Normally you don't need to change this. The default is false.

◆ setBoundingBox()

void Ogre::ManualObject::setBoundingBox ( const AxisAlignedBox box)
inline

Sets the bounding box.

Implements Ogre::ShadowCaster.

Reimplemented in Ogre::Entity, and Ogre::PortalBase.

◆ getWorldBoundingSphere()

virtual const Sphere& Ogre::MovableObject::getWorldBoundingSphere ( bool  derive = false) const
virtualinherited

Retrieves the worldspace bounding sphere for this object.

Reimplemented in Ogre::Entity, and Ogre::PortalBase.

◆ 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.

Referenced by Ogre::Light::setVisible().

◆ getVisible()

bool Ogre::MovableObject::getVisible ( void  ) const
inlineinherited

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

Remarks
Returns the value set by MovableObject::setVisible only.

◆ isVisible()

virtual bool Ogre::MovableObject::isVisible ( void  ) const
virtualinherited

Returns whether or not this object is supposed to be visible or not.

Remarks
Takes into account both upper rendering distance and visible flag.

Reimplemented in Ogre::StaticGeometry::Region.

Referenced by Ogre::Frustum::isCustomProjectionMatrixEnabled().

◆ setRenderingDistance()

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

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

Note
Camera::setUseRenderingDistance() needs to be called for this parameter to be used.
Parameters
distDistance beyond which the object will not be rendered (the default is 0, which means objects are always rendered).

◆ getRenderingDistance()

Real Ogre::MovableObject::getRenderingDistance ( void  ) const
inlineinherited

Gets the distance at which batches are no longer rendered.

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

◆ getRenderingMinPixelSize()

Real Ogre::MovableObject::getRenderingMinPixelSize ( ) const
inlineinherited

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

◆ setUserAny()

void Ogre::MovableObject::setUserAny ( const Any anything)
inlineinherited
Deprecated:
use UserObjectBindings::setUserAny via getUserObjectBindings() instead.

Sets any kind of user value on this object.

Remarks
This method allows you to associate any user value you like with this MovableObject. This can be a pointer back to one of your own classes for instance.

◆ getUserAny()

const Any& Ogre::MovableObject::getUserAny ( void  ) const
inlineinherited
Deprecated:
use UserObjectBindings::getUserAny via getUserObjectBindings() instead.

Retrieves the custom user value associated with this object.

◆ getUserObjectBindings() [1/2]

UserObjectBindings& Ogre::MovableObject::getUserObjectBindings ( )
inlineinherited

Return an instance of user objects binding associated with this class.

You can use it to associate one or more custom objects with this class instance.

See also
UserObjectBindings::setUserAny.

◆ getUserObjectBindings() [2/2]

const UserObjectBindings& Ogre::MovableObject::getUserObjectBindings ( ) const
inlineinherited

Return an instance of user objects binding associated with this class.

You can use it to associate one or more custom objects with this class instance.

See also
UserObjectBindings::setUserAny.

◆ setRenderQueueGroup()

virtual void Ogre::MovableObject::setRenderQueueGroup ( uint8  queueID)
virtualinherited

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

Reimplemented in Ogre::ParticleSystem, and Ogre::Entity.

◆ setRenderQueueGroupAndPriority()

virtual void Ogre::MovableObject::setRenderQueueGroupAndPriority ( uint8  queueID,
ushort  priority 
)
virtualinherited

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

Remarks
Render queues are grouped to allow you to more tightly control the ordering of rendered objects. Within a single render group there another type of grouping called priority which allows further control. If you do not call this method, all Entity objects default to the default queue and priority (RenderQueue::getDefaultQueueGroup, RenderQueue::getDefaultRenderablePriority), 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
queueIDEnumerated value of the queue group to use. See the enum RenderQueueGroupID for what kind of values can be used here.
priorityThe priority within a group to use.

Reimplemented in Ogre::ParticleSystem, and Ogre::Entity.

◆ getRenderQueueGroup()

uint8 Ogre::MovableObject::getRenderQueueGroup ( void  ) const
inlineinherited

virtual const Affine3& Ogre::MovableObject::_getParentNodeFullTransform ( void  ) const
virtualinherited

Return the full transformation of the parent sceneNode or the attachingPoint node.

Reimplemented in Ogre::InstancedEntity.

◆ 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.

◆ addQueryFlags()

void Ogre::MovableObject::addQueryFlags ( uint32  flags)
inlineinherited

As setQueryFlags, except the flags passed as parameters are appended to the existing flags on this object.

◆ 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.

◆ getQueryFlags()

uint32 Ogre::MovableObject::getQueryFlags ( void  ) const
inlineinherited

Returns the query flags relevant for this object.

◆ setDefaultQueryFlags()

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

Set the default query flags for all future MovableObject instances.

◆ getDefaultQueryFlags()

static uint32 Ogre::MovableObject::getDefaultQueryFlags ( )
inlinestaticinherited

Get the default query flags for all future MovableObject instances.

◆ 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 which when 'and'ed with the SceneManager's visibility mask can also make an object invisible.

◆ addVisibilityFlags()

void Ogre::MovableObject::addVisibilityFlags ( uint32  flags)
inlineinherited

As setVisibilityFlags, except the flags passed as parameters are appended to 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.

◆ getVisibilityFlags()

uint32 Ogre::MovableObject::getVisibilityFlags ( void  ) const
inlineinherited

Returns the visibility flags relevant for this object.

◆ setDefaultVisibilityFlags()

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

Set the default visibility flags for all future MovableObject instances.

◆ getDefaultVisibilityFlags()

static uint32 Ogre::MovableObject::getDefaultVisibilityFlags ( )
inlinestaticinherited

Get the default visibility flags for all future MovableObject instances.

◆ 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.

◆ getListener()

Listener* Ogre::MovableObject::getListener ( void  ) const
inlineinherited

Gets the current listener for this object.

◆ queryLights()

const LightList& Ogre::MovableObject::queryLights ( void  ) const
inherited

Gets a list of lights, ordered relative to how close they are to this movable object.

Remarks
By default, this method gives the listener a chance to populate light list first, if there is no listener or Listener::objectQueryLights returns NULL, it'll query the light list from parent entity if it is present, or returns SceneNode::findLights if it has parent scene node, otherwise it just returns an empty list.
The object internally caches the light list, so it will recalculate it only when object is moved, or lights that affect the frustum have been changed (
See also
SceneManager::_getLightsDirtyCounter), but if listener exists, it will be called each time, so the listener should implement their own cache mechanism to optimise performance.
This method can be useful when implementing Renderable::getLights in case the renderable is a part of the movable.
Returns
The list of lights use to lighting this object.

◆ getLightMask()

uint32 Ogre::MovableObject::getLightMask ( ) const
inlineinherited

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

Remarks
By default, this mask is fully set meaning all lights will affect this object

◆ setLightMask()

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

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

◆ _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.

◆ getLightCapBounds()

const AxisAlignedBox& Ogre::MovableObject::getLightCapBounds ( void  ) const
overridevirtualinherited

Gets the world space bounding box of the light cap.

Implements Ogre::ShadowCaster.

◆ getDarkCapBounds()

const AxisAlignedBox& Ogre::MovableObject::getDarkCapBounds ( const Light light,
Real  dirLightExtrusionDist 
) const
overridevirtualinherited

Gets the world space bounding box of the dark cap, as extruded using the light provided.

Implements Ogre::ShadowCaster.

◆ 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.

◆ getCastShadows()

bool Ogre::MovableObject::getCastShadows ( void  ) const
inlinevirtualinherited

Returns whether shadow casting is enabled for this object.

Implements Ogre::ShadowCaster.

◆ getReceivesShadows()

bool Ogre::MovableObject::getReceivesShadows ( )
inherited

Returns whether the Material of any Renderable that this MovableObject will add to the render queue will receive shadows.

◆ getPointExtrusionDistance()

Real Ogre::MovableObject::getPointExtrusionDistance ( const Light l) const
virtualinherited

Get the distance to extrude for a point/spot light.

Implements Ogre::ShadowCaster.

◆ getTypeFlags()

virtual uint32 Ogre::MovableObject::getTypeFlags ( void  ) const
virtualinherited

Get the 'type flags' for this MovableObject.

Remarks
A type flag identifies the type of the MovableObject as a bitpattern. This is used for categorical inclusion / exclusion in SceneQuery objects. By default, this method returns all ones for objects not created by a MovableObjectFactory (hence always including them); otherwise it returns the value assigned to the MovableObjectFactory. Custom objects which don't use MovableObjectFactory will need to override this if they want to be included in queries.

Reimplemented in Ogre::BillboardSet, Ogre::Entity, Ogre::ParticleSystem, Ogre::Frustum, Ogre::StaticGeometry::Region, and Ogre::Light.

◆ setDebugDisplayEnabled()

void Ogre::MovableObject::setDebugDisplayEnabled ( bool  enabled)
inlineinherited

Sets whether or not the debug display of this object is enabled.

Remarks
Some objects aren't visible themselves but it can be useful to display a debug representation of them. Or, objects may have an additional debug display on top of their regular display. This option enables / disables that debug display. Objects that are not visible never display debug geometry regardless of this setting.

◆ isDebugDisplayEnabled()

bool Ogre::MovableObject::isDebugDisplayEnabled ( void  ) const
inlineinherited

Gets whether debug display of this object is enabled.

◆ clearShadowRenderableList()

static void Ogre::ShadowCaster::clearShadowRenderableList ( ShadowRenderableList shadowRenderables)
staticinherited

Common implementation of releasing shadow renderables.

◆ extrudeVertices()

static void Ogre::ShadowCaster::extrudeVertices ( const HardwareVertexBufferSharedPtr vertexBuffer,
size_t  originalVertexCount,
const Vector4 lightPos,
Real  extrudeDist 
)
staticinherited

Utility method for extruding vertices based on a light.

Remarks
Unfortunately, because D3D cannot handle homogeneous (4D) position coordinates in the fixed-function pipeline (GL can, but we have to be cross-API), when we extrude in software we cannot extrude to infinity the way we do in the vertex program (by setting w to 0.0f). Therefore we extrude by a fixed distance, which may cause some problems with larger scenes. Luckily better hardware (ie vertex programs) can fix this.
Parameters
vertexBufferThe vertex buffer containing ONLY xyz position values, which must be originalVertexCount * 2 * 3 floats long.
originalVertexCountThe count of the original number of vertices, i.e. the number in the mesh, not counting the doubling which has already been done (by VertexData::prepareForShadowVolume) to provide the extruded area of the buffer.
lightPos4D light position in object space, when w=0.0f this represents a directional light.
extrudeDistThe distance to extrude.

◆ getAnimableValueNames()

const StringVector& Ogre::AnimableObject::getAnimableValueNames ( void  ) const
inlineinherited

Gets a list of animable value names for this object.

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

◆ 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.
