Hi Richard Thank you for the password. I started adding some documentation and I will expose all the difficulties I will face during cool 3D games development.
My personal test shows that parsing Collada to Whatever Internal Format in Flash is around 20 seconds, and accessing ActionScript code model is around 0.05 seconds which is much faster. ==> I made this test with embed Collada file in Flex. It was parsing at compiling time. I dint make same test with loaded and parsed at runtime models, but I suppose at runtime it would be slowly also, and even at compiling time 10-20 seconds is a very big time. Did you test the parsing speed? Please keep in mind that in Away 4 the parsing work will be done by CPU. We must clearly separate CPU and GPU work in runtime. My tests shows that in Away 3 the ActionScript code models rules against Collada but it has some UVW mapping issues while parsing. I want to ask - can I participate in testing AWD plug-in for 3Ds Max? This is one of major elements for many designers and developers and I would be glad to help in this project. Also I could participate on improving PyAWD as I know Python.
