Committed:	Wed Jun 9 16:16:33 2004 UTC (20 years, 1 month ago) by tim
File size:	4026 byte(s)
Log Message:	1. adding some useful math classes(Mat3x3d, Vector3d, Quaternion, Euler3) these classes use anonymous union and struct to support double[3], double[3][3] and double[4] 2. adding roll constraint algorithm
