Detailed Description

A field containing a single SbRotation (an arbitrary rotation).

SoSFRotations are written to file as four floating point values separated by whitespace. The 4 values represent an axis of rotation followed by the amount of right-handed rotation about that axis, in radians. For example, a 180 degree rotation about the Y axis is:

0 1 0  3.14159265
