I think this is because of the alpha blending of all slices - it's simply more pixels to blend when you get nearer. No idea how to make this faster, though!

Hello,

I have a question concerning the volume rendering: if the camera is far from the volume the framerate is about 30 or 40 Fps, if the camera is near of the volume the framerate decreases to 15 Fps. Is that normal ? It could become a problem for me with stereoscopic visualization.

Thanks a lot.

Vincent
