>> Are you going to upload a snippet into the libs for us all? Yeah, the minute I find how to rotate an object more than 180 degrees! I was able to deduce the data required by the KXPRot structure. I built all three rotation matrices, compounded them and converted to what I believe is a quartenian (x,y,z,w). Then I derived the 3 axis and angle. I was able to match the numbers I see when I rotate an object manually and go check the key info. This is only true, however, for rotations up to 180 degrees. When I have something rotating more than that, it gets clipped by 180 (i.e. 195 becomes 15). As I just "deduced" the equations, not really understood what I did, I still am working on that. By the way, after spending 30 straight hours writing my own matrix multiplication routines, matrix to quartenian conversion routines and quartenian derivation routines, I found out that all those functions are included in the IPAS libraries but they are not documented. Just take a look at 3D.H and QUAT.H for the function prototypes. All kinds of goodies. Not that it matters much for me as I probably wouldn't know what to do with them hadn't I gone through the process of developing my own. The only thing they served was to prove my equations as the results are identical. I developed this whole process of thought through MathCad. I guess the easiest way to "share" that would be to upload that document as it includes not only notes, but it also includes several equations I wouldn't know how to represent using straight ASCII. I can upload as a post script file if that makes anyone's life easier… I'm open to suggestions! And I'm also open to suggestions on my problems. So far I haven't heard a beep…
