Detailed Description

An object which renders geometry to a vertex.
Remarks
This is especially useful together with geometry shaders, as you can render procedural geometry which will get saved to a vertex buffer for reuse later, without regenerating it again. You can also create shaders that run on previous results of those shaders, creating stateful shaders.

Member Function Documentation

◆ bindVerticesOutput()

void Ogre::GL3PlusRenderToVertexBuffer::bindVerticesOutput ( Pass pass)
protected

◆ getMaxVertexCount()

unsigned int Ogre::RenderToVertexBuffer::getMaxVertexCount ( ) const
inherited

Get the maximum number of vertices that the buffer will hold.

Definition at line 70 of file OgreRenderToVertexBuffer.h.

◆ getOperationType()

const MaterialPtr& Ogre::RenderToVertexBuffer::getRenderToBufferMaterial ( )
inherited

Get the material which is used to render the geometry into the vertex buffer.

Definition at line 129 of file OgreRenderToVertexBuffer.h.

◆ getResetsEveryUpdate()

bool Ogre::RenderToVertexBuffer::getResetsEveryUpdate ( ) const
inherited

Does this object reset its buffer each time it updates?
