Different way to do 3d rotations?

Wrathnut · 2000-02-13T17:58:01

I''ve been fooling around trying to learn linear algebra so I can understand transformations that do the rotations of an object, now I actually didn''t learn much about it yet.. the book I have is my physics teacher''s, it''s way old. But I got to thinking about it and thought I might be able to solve my problem with spherical coordinates. Anyway to make a long story short I threw together a simple program in java that handle rotating and object by sending it angles then just doing some simple conversions. Courtesy of some very easy to understand calc 2 stuff. My program worked with only one logical error that I am working on fixing. As far as I can tell if optimized there might also be a speed increase in calculations(but only if you have many objects being manipulated). Anyway I was just wondering has anyone ever tried making a 3d engine that performs rotations this way? It''s very very easy to understand doing it this way than to do the complex matrix math I''ve seen used commonly for rotations.

I take it you aren''t the type of guy to try to do something new or different? I am not trying to make a fully formed 3d engine with all of the bells and whistles... Just trying to get it to work (displaying and rotating objects correctly), and also becuase I enjoy trying to figure things out and see if they can be done in a different way. The problems you bring up I can think of addressing in several different ways off the top of my head but I''m not trying to prove anything here I just was wondering if anyone had done it before. ^_^

Actually, I am the kind of guy to try something new and different. I just do enough reading to know that what you''re doing isn''t really new, and I''m just letting you know what pitfalls await you. Using spherical for rotations *has* been done before. It''s just no one has made a full-scale 3d engine out if it, because of the issues I''ve mentioned. I''m not trying to stifle you or anything, as I said, don''t take my word for it, think things through for yourself.
