If I give a velocity of (0, 10, 0) I want to get A and B accordingly.
0, 10, 0 direction is UP so the result should be the upper quarter.
I should change the following line:
float t = GetRandMinMax( -D3DX_PI, D3DX_PI );
float t = GetRandMinMax( A, B );
How do I calculate A and B based on the velocity (direction)?
