I was wondering if you have written or have plans to write a book on Game development and/or physics. Thanks again. Hi Glenn,

Your articles have been of great help for my thesis demo. I was wondering if you have written or have plans to write a book on Game development and/or physics. Thanks again.

Thanks for these wonderful articles they have helped me so much! I was wondering If you had written any articles about loading/rendering 3d models, or if you know of any good books about this as I haven't found any that seem to be good, thanks! Hey glen!

So, I start with a stationary object and expect it to speed up and reach steady state at the same speed as the current. It seems to do this but after reaching steady state, an oscillation develops that eventually diverges. I noticed that after a couple uses of coordinate transformations using quaternions, some of the x,y forces bleed into the z axis (which is a no-no for my 3dof sim). Do I need to normalize occasionally or take some action to prevent angular momentum from being developed somehow? The cube demo seems to have an angular velocity damping term added to prevent this from being a problem.. is it necessary because of precision issues with the implementation? Thanks for the discussion. I’m trying to simulate simple drifting of an object in a water flow.
