It *can* be a pretty long path from the raw data to a visualization. In
other words, a number of operations are often applied to incoming data to
get it into the final visualization form. Perhaps you can tell us more
about what you are doing to the data to visualize it.

You said it was "3D" data. So, for example, you might be reading in the
data as a volume and then computing an isosurface. Depending on the
distribution of samples in the volume and the isovalue, you might end up
generating polygonal meshes containing many millions of triangles.
