Hi all !, When I try to export xvolume figure with export vmrl bar menu, If isosurface off option is enabled then I obtain a small size file and I can't view it with a vmrl viewer (It only draws the axis into a empty figure). If isosurface opaque option is enabled then I can view this isosurface with a vmrl viewer but it only shows a grayscale figure without colours. I'm very interested to export the full volume figure to vrml. Exist a bug with the VMRL export option ? How can I do it programmatically from out of the xvolume tool ? Thanks in advance. Code to probe: ; Create a volume: vol = BYTSCL(RANDOMU((SEED=0),5,5,5)) vol = CONGRID(vol, 30,30,30) ; Display volume: XVOLUME, vol XVOLUME, vol
