ZXY to XYZ conversion
Author
Does anyone know how to convert from a ZXY rotation system to an XYZ rotation system?
E:cb woof!
That''s what I was thinking, but maybe he was using matricies.

I am. I also need to know how to convert from ZXY TO YXZ. I use ZXY because you can propigate(sp) the angles down to the child objects (add parent''s angles to child''s) and YXZ because my engine needs a "tilt, rotation, spin" type of rendering. I''m using XYZ because it''s easier to use when moving objects in my object editor.
Could I just say "y=z;x=x;z=y;"? I havn''t actually tried that. I didn''t think it''d work.
Just so you know, the "XYZ" are the rotations in angles and the order they''re computed.
ie: YXZ first rotates on the y axis giving me the "rotation", then on the x axis giving me the "tilt", then on the z axis giving me the "spin"

Try multiplying by this matrix...

That should switch 'em.

that does the exact same thing as what i originally said.
x''=x*0+y*0+z*1
y''=x*1+y*0+z*0
z''=x*0+y*1+z*0
or..
x''=z
y''=x
z''=y

x''=x*0+y*0+z*1
y''=x*1+y*0+z*0
z''=x*0+y*1+z*0
or..
x''=z
y''=x
z''=y

This brings me to another question:
If you had an array of chars, let''s say charray[64]. And let''s say that it contained this phrase "Ten animals I slam in a net". How would we create a function that turns that into "ten a nimals I slamina net"? Maybe this question is a little basic, but I don''t know how to approach that.
