334 unsigned int numtuples,
bool Download1D(int type, void *data, unsigned int dim, int numcomps, vtkIdType increment)
Download data from pixel buffer to the 1D array.
void BindToPackedBuffer()
Convenience methods for binding.
bool Upload3D(int type, void *data, unsigned int dims[3], int comps, vtkIdType increments[3], int components, int *componentList)
Update data to PBO mapped sourcing it from a 3D array.
