It was about time to start working on 3D with flash. I was already looking at Papervision3D some years ago, but I have never worked with. Then I’ve followed differents 3D engine like Sandy, Five3D, and Away3D.
Now that Stage3D and FP11 are out, it is time to start working with 3D in flash. However, it’s funny that my first try on a 3D Engine was made with a JS engine : Three.js
So in this post I just adapt my previous 3D example made with Three.js and WebGL and see how it runs with Away3D.
Finally I have chosen Away3D instead of those 3D engine for FP11 : minko, alternativa, flare3D, and adobe proscenium because it is free and has a great community support.
The quick demo.
