Hi,
Does anyone know how to get coordinates of every vertices of a convexHull object?
I have a convex hull object in my scene, and I want to get the coordinates of its all vertices (x,y,z) in every time step.
Thanks
Ehsan

Take a look at the GL_ShapeDrawer class it has everything you need.

Should be something like "centerOfMassTransform * point " for each point i.
point is the location of the vertex relative to the center of mass of the object, and centerOfMassTransform is a quaternion representing the translation and rotation of the object at some point in time.
Multiplying a quaternion and a point gives you a translated and rotated point.
