3D relief test

At my work I've had to make Relief render with 3dsMax & Maya, so I decided to test render also with personal picture, here is a test with my London Phonebox ! The Anaglyph version is done with the stereo cam of maya.



There is a ".mpo" file too, you can visualize the relief effect on your Nintendo 3ds without glasses ! juste copy the .mpo on your SD card, load it with your Nintendo 3ds and ... enjoy :)

Link to the .mpo : LondonPhoneBox .MPO
