Member Data Documentation

IndexData* Ogre::RenderOperation::indexData

Index data - only valid if useIndexes is true.

Definition at line 109 of file OgreRenderOperation.h.

size_t Ogre::RenderOperation::numberOfInstances

The number of instances for the render operation - this option is supported in only a part of the render systems.

Definition at line 118 of file OgreRenderOperation.h.

OperationType Ogre::RenderOperation::operationType

The type of operation to perform.

Definition at line 100 of file OgreRenderOperation.h.

bool Ogre::RenderOperation::renderToVertexBuffer

Specifies whether rendering to the vertex buffer.

Definition at line 121 of file OgreRenderOperation.h.

bool Ogre::RenderOperation::useGlobalInstancingVertexBufferIsAvailable

A flag to indicate that it is possible for this operation to use a global vertex instance buffer if available.

Definition at line 125 of file OgreRenderOperation.h.

bool Ogre::RenderOperation::useIndexes

Specifies whether to use indexes to determine the vertices to use as input.

If false, the vertices are simply read in sequence to define the primitives. If true, indexes are used instead to identify vertices anywhere in the buffer, and allowing vertices to be used more than once. If true, then the indexBuffer, indexStart and numIndexes properties must be valid.

Definition at line 106 of file OgreRenderOperation.h.

VertexData* Ogre::RenderOperation::vertexData

Vertex source data.

Definition at line 97 of file OgreRenderOperation.h.
