# Ogre::Rectangle2D Class Reference

Allows the rendering of a simple 2D rectangle This class renders a simple 2D rectangle; this rectangle has no depth and therefore is best used with specific render queue and depth settings, like RENDER_QUEUE_BACKGROUND and 'depth_write off' for backdrops, and RENDER_QUEUE_OVERLAY and 'depth_check off' for fullscreen quads.

## Member Function Documentation

virtual Matrix4 Ogre::MovableObject::_getParentNodeFullTransform | ( | void |  | ) | const`[virtual, inherited]`

| return the full transformation of the parent sceneNode or the attachingPoint node

virtual void Ogre::MovableObject::_notifyAttached | ( | Node * | parent,
|  | bool | isTagPoint = false
| ) | `[virtual, inherited]`

| Internal method called to notify the object that it has been attached to a node. Reimplemented in Ogre::Entity, and Ogre::ParticleSystem.

virtual void Ogre::SimpleRenderable::_notifyCurrentCamera | ( | Camera * | cam | ) | `[virtual, inherited]`

Internal method to notify the object of the camera to be used for the next rendering operation.

Remarks:
  Certain objects may want to do specific processing based on the camera position. This method notifies them incase they wish to do this.

Implements Ogre::MovableObject.

virtual void Ogre::Renderable::_updateCustomGpuParameter | ( | const GpuProgramParameters::AutoConstantEntry & | constantEntry,
|  | GpuProgramParameters * | params
| ) | const`[virtual, inherited]`

Update a custom GpuProgramParameters constant which is derived from information only this Renderable knows.

Remarks:
  This method allows a Renderable to map in a custom GPU program parameter based on it's own data. This is represented by a GPU auto parameter of ACT_CUSTOM, and to allow there to be more than one of these per Renderable, the 'data' field on the auto parameter will identify which parameter is being updated. The implementation of this method must identify the parameter being updated, and call a 'setConstant' method on the passed in GpuProgramParameters object, using the details provided in the incoming auto constant setting to identify the index at which to set the parameter.

  You do not need to override this method if you're using the standard sets of data associated with the Renderable as provided by setCustomParameter and getCustomParameter. By default, the implementation will map from the value indexed by the 'constantEntry.data' parameter to a value previously set by setCustomParameter. But custom Renderables are free to override this if they want, in any case.

Parameters:

  constantEntry | The auto constant entry referring to the parameter being updated
  params | The parameters object which this method should call to set the updated parameters.

Reimplemented in Ogre::TerrainRenderable.

References Ogre::GpuProgramParameters::AutoConstantEntry::data, Ogre::GpuProgramParameters::AutoConstantEntry::index, and params.

virtual void Ogre::SimpleRenderable::_updateRenderQueue | ( | RenderQueue * | queue | ) | `[virtual, inherited]`

Internal method by which the movable object must add Renderable subclass instances to the rendering queue.

Remarks:
  The engine will call this method when this object is to be rendered. The object must then create one or more Renderable subclass instances which it places on the passed in Queue for rendering.

Implements Ogre::MovableObject.

virtual void Ogre::MovableObject::addQueryFlags | ( | unsigned long | flags | ) | `[virtual, inherited]`

| As setQueryFlags, except the flags passed as parameters are appended to the existing flags on this object. Definition at line 203 of file OgreMovableObject.h.

virtual void Ogre::ShadowCaster::extrudeBounds | ( | AxisAlignedBox & | box,
|  | const Vector4 & | lightPos,
|  | Real | extrudeDist
| ) | const`[protected, virtual, inherited]`

Utility method for extruding a bounding box.

Parameters:

  box | Original bounding box, will be updated in-place
  lightPos | 4D light position in object space, when w=0.0f this represents a directional light
  extrudeDist | The distance to extrude

void Ogre::ShadowCaster::extrudeVertices | ( | HardwareVertexBufferSharedPtr | vertexBuffer,
|  | size_t | originalVertexCount,
|  | const Vector4 & | lightPos,
|  | Real | extrudeDist
| ) | `[static, inherited]`

Utility method for extruding vertices based on a light.

Remarks:
  Unfortunately, because D3D cannot handle homogenous (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:

  vertexBuffer | The vertex buffer containing ONLY xyz position values, which must be originalVertexCount * 2 * 3 floats long.
  originalVertexCount | The count of the original number of vertices, ie 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.
  lightPos | 4D light position in object space, when w=0.0f this represents a directional light
  extrudeDist | The distance to extrude

virtual void Ogre::ShadowCaster::generateShadowVolume | ( | EdgeData * | edgeData,
|  | HardwareIndexBufferSharedPtr | indexBuffer,
|  | const Light * | light,
|  | ShadowRenderableList & | shadowRenderables,
|  | unsigned long | flags
| ) | `[protected, virtual, inherited]`

Generates the indexes required to render a shadow volume into the index buffer which is passed in, and updates shadow renderables to use it.

Parameters:

  edgeData | The edge information to use
  indexBuffer | The buffer into which to write data into; current contents are assumed to be discardable.
  light | The light, mainly for type info as silhouette calculations should already have been done in updateEdgeListLightFacing
  shadowRenderables | A list of shadow renderables which has already been constructed but will need populating with details of the index ranges to be used.
  flags | Additional controller flags, see ShadowRenderableFlags

virtual const AxisAlignedBox& Ogre::SimpleRenderable::getBoundingBox | ( | void |  | ) | const`[virtual, inherited]`

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

bool Ogre::MovableObject::getCastShadows | ( | void |  | ) | const`[virtual, inherited]`

| Returns whether shadow casting is enabled for this object. Implements Ogre::ShadowCaster. Definition at line 238 of file OgreMovableObject.h.

virtual bool Ogre::Renderable::getCastsShadows | ( | void |  | ) | const`[virtual, inherited]`

Method which reports whether this renderable would normally cast a shadow.

Remarks:
  Subclasses should override this if they could have been used to generate a shadow.

Reimplemented in Ogre::StaticGeometry::GeometryBucket, and Ogre::SubEntity.

Definition at line 154 of file OgreRenderable.h.

virtual const PlaneList& Ogre::Renderable::getClipPlanes | ( |  | ) | const`[virtual, inherited]`

|  | Real | dirLightExtrusionDist
| ) | const`[virtual, inherited]`

| Overridden member from ShadowCaster. Implements Ogre::ShadowCaster.

EdgeData* Ogre::MovableObject::getEdgeList | ( | void |  | ) | `[virtual, inherited]`

| Define a default implementation of method from ShadowCaster which implements no shadows. Implements Ogre::ShadowCaster. Reimplemented in Ogre::Entity, and Ogre::StaticGeometry::Region. Definition at line 213 of file OgreMovableObject.h.

|  | const Light * | light
| ) | const`[protected, inherited]`

| Helper moethod for calculating extrusion distance.

const AxisAlignedBox& Ogre::MovableObject::getLightCapBounds | ( | void |  | ) | const`[virtual, inherited]`

| Overridden member from ShadowCaster. Implements Ogre::ShadowCaster.

Remarks:
  Directional lights, which have no position, will always be first on this list.

Implements Ogre::Renderable.

virtual const MaterialPtr& Ogre::SimpleRenderable::getMaterial | ( | void |  | ) | const`[virtual, inherited]`

Retrieves a weak reference to the material this renderable object uses.

Remarks:
  Note that the Renderable also has the option to override the getTechnique method to specify a particular Technique to use instead of the best one available.

Implements Ogre::Renderable.

virtual const String& Ogre::SimpleRenderable::getMovableType | ( | void |  | ) | const`[virtual, inherited]`

| Overridden from MovableObject. Implements Ogre::MovableObject.

virtual const String& Ogre::SimpleRenderable::getName | ( | void |  | ) | const`[virtual, inherited]`

| Returns whether or not this Renderable wishes the hardware to normalise normals. Reimplemented in Ogre::SubEntity. Definition at line 138 of file OgreRenderable.h.

virtual unsigned short Ogre::Renderable::getNumWorldTransforms | ( | void |  | ) | const`[virtual, inherited]`

Returns the number of world transform matrices this renderable requires.

Remarks:
  When a renderable uses vertex blending, it uses multiple world matrices instead of a single one. Each vertex sent to the pipeline can reference one or more matrices in this list with given weights. If a renderable does not use vertex blending this method returns 1, which is the default for simplicity.

Reimplemented in Ogre::BorderRenderable, and Ogre::SubEntity.

Definition at line 104 of file OgreRenderable.h.

virtual Node* Ogre::MovableObject::getParentNode | ( | void |  | ) | const`[virtual, inherited]`

Returns the node to which this object is attached.

Remarks:
  A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. Both are Node subclasses so this method will return either.

virtual SceneNode* Ogre::MovableObject::getParentSceneNode | ( | void |  | ) | const`[virtual, inherited]`

Returns the scene node to which this object is attached.

Remarks:
  A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. This method will return the scene node of the parent entity if the latter is true.

Real Ogre::MovableObject::getPointExtrusionDistance | ( | const Light * | l | ) | const`[virtual, inherited]`

| Get the distance to extrude for a point/spot light. Implements Ogre::ShadowCaster.

|  | Real | extrusionDist,
|  | unsigned long | flags = 0
| ) | `[virtual, inherited]`

| Define a default implementation of method from ShadowCaster which implements no shadows. Implements Ogre::ShadowCaster. Reimplemented in Ogre::Entity, and Ogre::StaticGeometry::Region.

Real Ogre::Rectangle2D::getSquaredViewDepth | ( | const Camera * | cam | ) | const`[virtual]`

Returns the camera-relative squared depth of this renderable.

Remarks:
  Used to sort transparent objects. Squared depth is used rather than actual depth to avoid having to perform a square root on the result.

Implements Ogre::Renderable.

Definition at line 65 of file OgreRectangle2D.h.

References Ogre::Real.

virtual Technique* Ogre::Renderable::getTechnique | ( | void |  | ) | const`[virtual, inherited]`

Retrieves a pointer to the Material Technique this renderable object uses.

Remarks:
  This is to allow Renderables to use a chosen Technique if they wish, otherwise they will use the best Technique available for the Material they are using.

Reimplemented in Ogre::StaticGeometry::GeometryBucket, and Ogre::SubEntity.

Definition at line 69 of file OgreRenderable.h.

virtual UserDefinedObject* Ogre::MovableObject::getUserObject | ( | void |  | ) | `[virtual, inherited]`

| Retrieves a pointer to a custom application object associated with this movable by an earlier call to setUserObject. Definition at line 171 of file OgreMovableObject.h.

virtual const AxisAlignedBox& Ogre::MovableObject::getWorldBoundingBox | ( | bool | derive = false | ) | const`[virtual, inherited]`

| Reimplemented from Ogre::SimpleRenderable.

void Ogre::Rectangle2D::getWorldTransforms | ( | Matrix4 * | xform | ) | const`[protected, virtual]`

virtual bool Ogre::MovableObject::isAttached | ( | void |  | ) | const`[virtual, inherited]`

| Returns true if this object is attached to a SceneNode or TagPoint.

virtual bool Ogre::MovableObject::isInScene | ( | void |  | ) | const`[virtual, inherited]`

virtual bool Ogre::MovableObject::isVisible | ( | void |  | ) | const`[virtual, inherited]`

| Returns whether or not this object is supposed to be visible or not. Reimplemented in Ogre::StaticGeometry::Region.

virtual void Ogre::MovableObject::removeQueryFlags | ( | unsigned long | flags | ) | `[virtual, inherited]`

| As setQueryFlags, except the flags passed as parameters are removed from the existing flags on this object. Definition at line 207 of file OgreMovableObject.h.

void Ogre::SimpleRenderable::setBoundingBox | ( | const AxisAlignedBox & | box | ) | `[inherited]`

void Ogre::MovableObject::setCastShadows | ( | bool | enabled | ) | `[inherited]`

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.

Definition at line 236 of file OgreMovableObject.h.

void Ogre::Rectangle2D::setCorners | ( | Real | left,
|  | Real | top,
|  | Real | right,
|  | Real | bottom
| ) |

Sets the corners of the rectangle, in relative coordinates.

Parameters:

  left | Left position in screen relative coordinates, -1 = left edge, 1.0 = right edge top Top position in screen relative coordinates, 1 = top edge, -1 = bottom edge right Right position in screen relative coordinates bottom Bottom position in screen relative coordinates

void Ogre::Renderable::setCustomParameter | ( | size_t | index,
|  | const Vector4 & | value
| ) | `[inherited]`

Sets a custom parameter for this Renderable, which may be used to drive calculations for this specific Renderable, like GPU program parameters.

Remarks:
  Calling this method simply associates a numeric index with a 4-dimensional value for this specific Renderable. This is most useful if the material which this Renderable uses a vertex or fragment program, and has an ACT_CUSTOM parameter entry. This parameter entry can refer to the index you specify as part of this call, thereby mapping a custom parameter for this renderable to a program parameter.

Parameters:

  index | The index with which to associate the value. Note that this does not have to start at 0, and can include gaps. It also has no direct correlation with a GPU program parameter index - the mapping between the two is performed by the ACT_CUSTOM entry, if that is used.
  value | The value to associate.

Definition at line 171 of file OgreRenderable.h.

void Ogre::SimpleRenderable::setMaterial | ( | const String & | matName | ) | `[inherited]`

virtual void Ogre::MovableObject::setQueryFlags | ( | unsigned long | flags | ) | `[virtual, inherited]`

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.

Definition at line 199 of file OgreMovableObject.h.

virtual void Ogre::Renderable::setRenderDetailOverrideable | ( | bool | override | ) | `[virtual, inherited]`

Sets whether this renderable's chosen detail level can be overridden (downgraded) by the camera setting.

Parameters:

  override | true means that a lower camera detail will override this renderables detail level, false means it won't.

Definition at line 235 of file OgreRenderable.h.

virtual void Ogre::SimpleRenderable::setRenderOperation | ( | const RenderOperation & | rend | ) | `[virtual, inherited]`

virtual void Ogre::MovableObject::setRenderQueueGroup | ( | RenderQueueGroupID | queueID | ) | `[virtual, inherited]`

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.

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

virtual void Ogre::MovableObject::setUserObject | ( | UserDefinedObject * | obj | ) | `[virtual, inherited]`

Call this to associate your own custom user object instance with this MovableObject.

Remarks:
  By simply making your game / application object a subclass of UserDefinedObject, you can establish a link between an OGRE instance of MovableObject and your own application classes. Call this method to establish the link.

Definition at line 167 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setVisible | ( | bool | visible | ) | `[virtual, inherited]`

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 visbility 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 visbility changes are best done using this method; large or more longer term changes are best done by detaching.

Reimplemented in Ogre::Light.

void Ogre::SimpleRenderable::setWorldTransform | ( | const Matrix4 & | xform | ) | `[inherited]`

virtual void Ogre::ShadowCaster::updateEdgeListLightFacing | ( | EdgeData * | edgeData,
|  | const Vector4 & | lightPos
| ) | `[protected, virtual, inherited]`

Tells the caster to perform the tasks necessary to update the edge data's light listing.

Can be overridden if the subclass needs to do additional things.

Parameters:

  edgeData | The edge information to update
  lightPos | 4D vector representing the light, a directional light has w=0.0
