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.
