Hi,
In the following link i cant understand the angle A which is defined as angle of V with respect to X-axis.
https://www.siggraph.org/education/materials/HyperGraph/modeling/mod_tran/3drota.htm
This means i cant understand following two things:
1. How to rotate V about X axis to put V in XZ plane
and
2. How to rotate V about Y to align it with Z axis.
Some body please guide me.
Zulfi.
