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.

Thanks for all. I got the solution after getting the normal to that
vector.

Kalai
