[This does not appear to be related to the previous message in this 
thread; please start new threads as appropriate.]

openvrml::rotation and openvrml::quatf (see basetypes.h) provide 
conversions between the conventional VRML axis+angle format and 
quaternions. There are also constructor functions to create an 
openvrml::mat4f from a rotation or a quatf and functions to get a 
rotation from a mat4f. However, there is no code in OpenVRML that deals 
with Euler angles.
