ComputeMass() public abstract method

Compute the mass properties of this shape using its dimensions and density. The inertia tensor is computed about the local origin, not the centroid.
public abstract ComputeMass ( MassData &massData, float density ) : void
massData MassData Returns the mass data for this shape
density float
return void
