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
vbuffPointer to an array of Vertex objects that describe the vertices that are to be added to the GeometryBuffer.
vertex_countThe number of Vertex objects from the array vbuff that are to be added to the GeometryBuffer.

Reimplemented from CEGUI::OpenGLGeometryBufferBase.
