Dear All,
I am developing a 3D car game in C++ using openGL. To calculate the
Ground Velocity, I need the formula to calculate tangent for 3D
vector. I got the tangent for 2D vector from some game samples (i.e.,
Tangent for 2D vector (x,y) = (-y,x)). Please help me to find out the
tangent for 3D vector.
(-y,x) is perpendicular to (x,y). ((y,-x) is also perpendicular in the other
direction.)
For the vector (x,y,z), there are any number of vectors perpendicular to it.
You need to be clearer as to what you need.
