constants to describe the axis convention.

XYZ - order of the axes

s/r - whether the rotations are applied to a static or

rotating frame.

EulerAnglesClass
|
|
|
|
The purpose for this class is mainly for conversion. You can
|
|
choose a convention for the order of your rotations and then
|
|
convert matrices into a set of euler angles. You don't really
|
|
want to use this at run-time to convert matrices into angles.
|
|
|
|
The guts of this implementation is based on the article in Graphics
|
|
Gems IV by Ken Shoemake. The original article is on page 222.
