I am trying to animate a CT Scan of an arm. The result should be an animation in which the arm reveals the inside as a gradient clipping motion. At clipping point 0 I want to show frame "alpha" of the real CT slice and at clipping point 500 I want show frame "omega" of the real CT slice. Like cutting through the arm and showing each CT slice at the exact location. Any hints on how to approach this?

Edit: The direction and shape of the clipping should be freely adjustable without changing the orientation of the sequence or its content. I would like light it with an hdri and render it with cycles.

I added two animations here that visualize my issue.

  • $\begingroup$ I have an OBJ with texture of the slit scan and the image sequence in PNG RGBA. I want to light the mesh/scene with an HDRI. I am not going for the unlit vertex color or point cloud. $\endgroup$

  • $\begingroup$ If you have the image sequence already, just add an image sequence node and animate it's offset input. $\endgroup$
