Yesterday I made port of Collajader 3D tester to Android. Port was quite simple. The only problem was how to replace mx:Canvas in Spark architecture. It’s quite easy, use s:SpriteVisualElement.
You can test performance of Alternativa 3D on Android platform. UI is clumsy. Primary goal of this release was just to test behavior of Alternativa 3D 7 on Android. It seems that it works
The only problem of exported model is that it contains a lot of other information that you do not need for rendering.
I created simple tool Collajader which is able to display content defined in Collada format in the web browser. You don’t need to start any 3D software and you can still finetune some details of the model.
