Member Function Documentation

BuildVBO()

void vtkOpenGLContextDeviceBufferObjectBuilder::BuildVBO	(	vtkOpenGLHelper *	cbo,
		vtkDataArray *	positions,
		vtkUnsignedCharArray *	colors,
		vtkFloatArray *	tcoords,
		std::uintptr_t	cacheIdentifier,
		vtkRenderWindow *	renderWindow
	)

Build vertex buffer objects for these data arrays and add vertex attribute specifications to the vertex array object.

Existing VBOs may be reused when a VBOGroup already exists for the cacheIdentifier and the data arrays have not been modified since last upload.

Erase()

void vtkOpenGLContextDeviceBufferObjectBuilder::Erase	(	std::uintptr_t	cacheIdentifier,
		vtkRenderWindow *	renderWindow
	)

Erase cache entry for given identifier.
