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.

inlineinherited

What type of primitives does this object generate?

Definition at line 79 of file OgreRenderToVertexBuffer.h.

virtual void Ogre::D3D11RenderToVertexBuffer::getRenderOperation ( RenderOperation op)
virtual

Get the render operation for this buffer.

Implements Ogre::RenderToVertexBuffer.

Remarks
Use this object to set the elements of the buffer. Object will calculate buffers on its own. Only one source allowed!
void Ogre::D3D11RenderToVertexBuffer::reallocateBuffer ( size_t  index)
virtual void Ogre::RenderToVertexBuffer::reset ( void  )
inlinevirtualinherited

Reset the vertex buffer to the initial state.

In the next update, the source renderable will be used as input.
