Hi all, I have uploaded a new medical animation tutorial. In this short video I use Blender 2.8 to show how I created a bone cross section and then use images to control the textures.

Hope you enjoy.

  1. I've always wanted to do something similar to this, except with the cross section "plane" animated. At present, however, it seems this remains difficult to accomplish with Blender Boolean, and replicating complex interior geometry is also a challenge.

    If your volume is full of discontinuous voids, it might be doable with an animated vector displacement map to "fake" it, but accomplish doing so very efficiently, though it wouldn't see farther than the rendered voids.

    It would seem the best way would be to be able to define internal geometry using dense voxel data and create geometry with a meshing algorithm. But that would be computationally intensive.

    Nonetheless, I look forward to future work. Thanks for sharing.

  2. Very inneficient way to merge verticles..
    in 2.8+ use automerge or slide verts with double G and apply merge by distance.

  3. When merging the verts I wanted to merge at center, Automerge is a great new feature, it gives a similar workflow to the tweak tool in Softimage which I missed. But you cant merge center with it as far as I can see. In the video I selected two verts, then merged at center. After that I just needed to select the next two points and hit g. I am using the industry standard keymap rather than the blender keymap. So sliding with double G wouldn't work either, and it still wont merge at center and requires more input.
