Load obj file in bullet

Post by sienaiwun » Wed Mar 27, 2013 2:28 am

Hi.
I am new in bullet physics, I use bullet to simulate a dynamic scene composed of many .obj model files.
My question is that: in the bullet sdk, the only .obj model used example is the "App_ConvexDecompositionDemo" and the decomposition thing is used. Must it be? If I do not use the decomposition thing, the model do not react well (for example, a stick do not falls, and stand still instead), does the decomposition thing is the reason? Or, the decomposition takes too much time to deal with a, for example 8000 triangles ,model, Is there something I can do to deal with it?
