Hi, All
I have two questions about Vector3d.
1. If I have a Vector3d, e.g., (1.0, 0.1, 0.1), and I want to rotate it with 45 degrees about x-axis, 135 degrees about y-axis, then 300 degrees about z-axis. After these rotations, how to find the new Vector?
2. How to find a Vector which is perpendicular to another Vector, e.g., (1.0, 0.1, 0.1) ?
Thanks a lot.
