How do you change cartesian to spherical coordinates?

Answer 1

float2 CartesianToSpherical(float x, float y, float z)

{

float2 SphericalPos;

SphericalPos.x = atan2(x,z)/6.28318f;

if(SphericalPos.x < 0.0f)

SphericalPos.x += 1.0f;

SphericalPos.y = atan2(sqrt(x*x+z*z),y)/3.14159f;

return SphericalPos;

}
