Member Function Documentation

void CEGUI::OpenGL3GeometryBuffer::appendGeometry	(	const Vertex *const	vbuff,
		uint	vertex_count
	)		[virtual]

Append a number of vertices from an array to the GeometryBuffer.

Parameters:

vbuff	Pointer to an array of Vertex objects that describe the vertices that are to be added to the GeometryBuffer.
vertex_count	The number of Vertex objects from the array vbuff that are to be added to the GeometryBuffer.

Reimplemented from CEGUI::OpenGLGeometryBufferBase.
