This utility provides GUI interface to convert Euler angles to Quaternions around X,Y and Z (roll, pitch and yaw) axis and performs conjugate, addition, subtraction, mulitplication, great circle interpolation operations on converted Quaternions. Allowed rotation sequences are XYZ, XZY, YXZ, YZX, ZXY, ZYX. Input of Euler angles can be either in radians or degrees. Batch processing for Euler angles to quaternion is supported. You can use the software free for 30 days evaluation.
