Import cached/saved animation result from external simulation tool

Hi all,

I am in the process of writing some simulation software and want to provide some nice renders besides the default OpenGL output. I thought of using Blender. The idea is this: I use my software to perform the simulation and write out the results to OBJ files. (One per frame of animation). I then want to import this into Blender and render the animation, perhaps with some fancy camera moves. :slight_smile:

My question is, how would you approach this? Load the first “frame” end then set up shape keys with the geometry info from the next frames? If anyone could point me to some existing scripts/tutorials (even if not directly related, but touching on a similar topic) that might help me out, I would appreciate it.

Kind regards.

You could look at the existing blender obj {im,ex}porters.

Or the obj file format documentation even.
