Hi everyone, i''m currently working on skeletal animation and looking around i have seen a lot of tutorial using thier own matrix multiplication, why ? isn''t more easyer to perform a translation and a multiplication using opengl commands ? is there a speed issue or what ? can anyone tell me ? thanks

Sometimes your own matrix routines can be a better idea for a certain situation... But if you can do with the OpenGL routines for translation/rotation... Then do it, as they are a much better choice.

not all cards support hardware matrix ops, meaning they use software which are damn slow. this is why a lot of routines use their own matrix functions which can be optimized in assembly. hell, even unoptimized matrix ops in software are better then OGL''s software ones .
