Update origin point with transformations? : I want to be able to update a point (center of object) with the transformations applied to the object. I already have the transformations working perfectly fine but what I need to do update my object center point with the transformations so that I can do some others stuff with them. The problem is that if you multiply the model matrix with the vector(0, 0, 0) (origin of object) it produces a vector(0, 0, 0). That is where I am stuck.
