Alternativa3D 8.32.0 jiglib car physics racing with textured and shadow cube.
Video alternativa3d and away3d test. Well you know away3d and jiglib and I like to know that is different if last one can be improve with Alternativa3D 8.32.0 Alternativa3D 8.32.0. It's like a "Away3d vs Alternativa3D", then who winer? Well I don't know, they both are awesome. I have already taken current Jiglibflash update for Away3D 4.1 alpha dev branch (stage3d) and hello word alternativa3d example.If you want to drive, you can made a click on flash container and drive a car using arrow key and space key for handbrake.
