overriding inertia tensor and mass

Post by atul »

Hi,
I want to override the value of inertia tensor, center of mass and mass of a body. My basic idea is to make one body behave like other under same circumstances of application of force and collision condition<disregarding the apparent shape of the body>. A simple example is dropping objects A and B. Both will make different number of bounces. I want to experiment whether applying A's three properties <inertia, mass, c mass> to B will make behave B like A.
My questions are as follows -
a. Are these three quantities sufficient. I looked at equation of dynamics and feel they are. But would like to confirm.
b. I am using PhysX to implement my stuff. The masses and inertial parameters are very large. Not matching with my hand calculations anywhere. What could be the possible reason? <I don't know it is right forum to ask this question?>
thanks and regards,
