I'd like to make a 3d image from a 3d graphics. Unfortunately Rasterize@Graphics3D[Sphere[]] gives a 2d image, is there any function like a Rasterize3D that does this?

  • Which method of Stereoscopy do you want to use? – rhermans Aug 20 '15 at 15:21
  • @rhermans I'm confused, why is any stereoscopy necessary to generate an Image3D object? – M.R. Aug 20 '15 at 16:18
  • My confusion, I thought you wanted a flat 2D image not an Image3D object. Something like a color anaglyph (red/blue glases) or a stereogram that you haven't specified. My mistake for trying to think about more than one thing at the time. – rhermans Aug 20 '15 at 16:24

    good question , but I think the answer is hold your breath for wolfram to implement rasterize3d. (assuming you need a general solution.. if your graphics3d contains only simple objects there may be ways) – george2079 Aug 20 '15 at 16:57

  • 5 months passed, there is still no solution to this? Unbelievable. I think your question is very useful, it is not getting enough attention. – matheorem Jan 20 '16 at 05:20
  • But if you want generate image3d from such as DensityPlot3D, this can be done by calculating the data on a regular mesh first, and using Image3D[data] to generate 3d object – matheorem Jan 20 '16 at 08:41
  • I have a tool that will do this with Region data if you'd like. I can package it up and put it on Github or some such. – flip Apr 20 '16 at 09:39
  • http://http.developer.nvidia.com/GPUGems3/gpugems3_ch29.html section "Shape Representation" discusses a method called "depth peeling" to convert 3D mesh to volumetric data. – masterxilo Jun 26 '16 at 20:25
  • This answer: http://mathematica.stackexchange.com/a/33277/6804 gives an approach that rasterizes individual 2D slices at different heights and stacks them into a 3d image. – masterxilo Jun 26 '16 at 20:30
