Detailed Description

Class for rendering the border of a BorderPanelOverlayElement.

We need this because we have to render twice, once with the inner panel's repeating material (handled by superclass) and once for the border's separate material.

Constructor & Destructor Documentation

BorderRenderable()

Ogre::BorderRenderable::BorderRenderable ( BorderPanelOverlayElement *  parent )

inline

Constructed with pointers to parent.

References Ogre::Renderable::getPolygonModeOverrideable().

Member Function Documentation

getMaterial()

const MaterialPtr & Ogre::BorderRenderable::getMaterial ( void  ) const

inlineoverridevirtual

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

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.

getRenderOperation()

void Ogre::BorderRenderable::getRenderOperation ( RenderOperation &  op )

inlineoverridevirtual

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

Implements Ogre::Renderable.

getWorldTransforms()

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

inlineoverridevirtual

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

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.

Note

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

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

Note

If MeshManager::getBonesUseObjectSpace() is true, the first matrix must contain the world transform of the object, and the rest of the matrices must contain the bone transforms in object space.

Implements Ogre::Renderable.

References Ogre::OverlayElement::getWorldTransforms().

getNumWorldTransforms()

unsigned short Ogre::BorderRenderable::getNumWorldTransforms ( void  ) const

inlineoverridevirtual

Returns the number of world transform matrices this renderable requires.

When a renderable uses GPU 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.

Note

If MeshManager::getBonesUseObjectSpace() is true, this method must return numBones + 1

Reimplemented from Ogre::Renderable.

getSquaredViewDepth()

Real Ogre::BorderRenderable::getSquaredViewDepth ( const Camera *  cam ) const

inlineoverridevirtual

Returns the squared distance between the camera and this renderable.

Used to sort transparent objects. Squared distance is used to avoid having to perform a square root on the result.

Implements Ogre::Renderable.

References Ogre::OverlayElement::getSquaredViewDepth().

getLights()

const LightList & Ogre::BorderRenderable::getLights ( void  ) const

inlineoverridevirtual

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

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

Implements Ogre::Renderable.
