What is the precise definition of the rotation method used for Meta particles in EDEM?
I have attempted to determine the defined rotation method through various tests, but I have been unable to figure it out. It seems certain that it is not using the Rodrigues rotation vector method. It appears to be either an Euler angle rotation or another method, but which specific rotation convention is being used?
During my testing, I also noticed that the input values are sometimes automatically adjusted arbitrarily. Why does this happen?
For example, if I input (1.57, 1.57, 1.57) [rad] into the Rotation X/Y/Z fields, it automatically converts the values to (0, 3.1392, 1.5708) [rad]. When I plot these two sets of values assuming an X-Y-Z Euler rotation order, they result in completely different coordinate orientations. How exactly does the internal logic work to cause this strange conversion?
Best regards,
