Rubik's Cube Camera Mapping UV projection TEST + Blender + After Effects


Another (very) brief experiment using the UV projection modifier in Blender.
The resulting 3D animation is made based on a single still photograph that was projected onto some basic cube shapes, then a separate camera was used to render a short animation.
The cubes only have 3 sides each and are simple flat planessubdivided and rendered with a normal map.

The scene was re-lit in Blender in order to create realistic 3d shadows. This was the part that really amazed me while doing it in Blender 2.62: The GLSL preview allowed me to make changes to the lighting and see exactly what it would render like in realtime!
I haven't used Blender that much since it's complete UI overhaul and the last project I used it for was in Blender 2.49 using a crappy computer. It's taken me a little while to adjust to the new UI - and initially I was sceptical of the changes are meerly cosmetic and a case of bulking out the software a bit too much - but I am won over.
Blender truly is the best software progrma out there for 3D animation and modelling. It always was fairly intuitive in terms of it's workflow but occasionally you could very easily get lost in it's little buttons and menus. Versions 2.5+ have worked hard on fixing that.

Ok, lets get back to the little test footage above.
The cubes lighting up was added in After Effects using a keyframed 'Paint Fill' plugin. set to 'add'.
The 'music' (cough!) was thrown together and added also in After Effects.

Problems? Well, it's basically just a few cubes with textures projected onto them and there was no attempt made to make a more complex Rubik's Cube shape that would have added more realism. But camera projection mapping is all about saving time and getting a animated shot from a still photograph so, from that point of perspective, it does what's expected of it.

I'm looking forward to doing more experiments in camera mapping to see what effects I could use in my planned sci-fi feature.

Stuff used: Blender 3d, Adobe After Effects, Reaper, Nikon Coolpix camera for taking picture (obviously!)

how make it that..? teach me, I'm confused about cameera mapping
