Hi. I want to load 3d models in my opengl based game. I have looked into Collada DOM, and I think this is used to load 3d models from studio max and maya ( isnt it ? ), and also it supports animation. So question one: is my assumption about it is true ? Second question is I have downloaded collada-dom-vc8 sdk and when tried to run COLLADA_RT_VIEWER.exe, it gives me error of "missing cg.dll". I have searched through whole system but no such file is found. I am using windows vista home, visual studio 2005. Any help ? Thanks

Hi sfx81 ,

Ya collada dom will load any file with .dae extension.it will supports
animation.But this is just a data base its contains all the
library information,so from there you have to extract the
innformatiom which you required for animation.

http://www.wazim.com/Collada_Tutorial_1.htm

Please refer this article about Collada format and animation.This will
give you good idea.

For your second question i am not sure,but i will update you ASAP.

Regards,
Parmar.

Bad idea (reading a text file and process and XML file to load a model on your game in real time). COLLADA is an intermediate or exchange file format. Consider using another binary format or develop your own.

Read my thesis to know more:

Hope this helps.

Kudos to Ricardo for delivering this often miscredited piece of truth.

Collada, based on my experience (mostly as an hobbyst but also partially in a small engineering-related company) has surprisingly little to offer to the SOHO initiatives (you may want to check out how my opinion evolved among the years if google still remembers the board messages). I've considered posting something more on the issue but I am not frankly sure you would consider those personal opinions valuable so I made a step back and deleted them.

Yeah, I use the Horde3D engine (open source OpenGL-based renderer), which converts COLLADA (.dae) files into a binary format. My game then loads the binary files.
