OpenGL3 based implementation of the GeometryBuffer interface.
void CEGUI::OpenGL3GeometryBuffer::appendGeometry | ( | const Vertex *const | vbuff, |
uint | vertex_count | ||
) | [virtual] |
Append a number of vertices from an array to the GeometryBuffer.
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.
