Today I was doodling around with the fantastic idea of Noah Paessel (http://paessel.com/blog/2014/08/24/converting-pixels-to-voxels-in-blender-with-pythong.html). I learnt quite a few things out of his code especially the strange way bpy indexes the pixels of an image.
So I came out with a script shamefully inspired by his work . It builds wipe transitions between several black and white images. Every pixel is turned into a cube. The shades are created by the distance of the cube from the lightsource. Of course, it has to be watched far from the screen because it is only 46 x 40 pixels images…
To play with the script : pixels.blend
