Undergrad Point movement on a surface of a sphere
Thanks Arman, I will try to test that. Seems simple. I found a post on another form related to this problem from a game programming perspective, I haven't got this to work yet. 1) Center the sphere to 0,0,0 global coordinates. 2) Get the up-vector of the airplane, which is a also the normal of...- Sobe118

Undergrad Point movement on a surface of a sphere
The point would normally only ever have velocities on its green and red arrows. The radius is fixed. Think of it as if a car is driving on a very tiny earth- Sobe118

Undergrad Point movement on a surface of a sphere
Yes, it is very commonly computed in video games. Self driven point on the surface of a sphere. I can't find any math on this topic. I've been looking for a week.- Sobe118

Undergrad Point movement on a surface of a sphere
I'm trying to find the resulting location of a point on a sphere in spherical coordinates or Cartesian. Based on velocities from the perspective of an object on the sphere. So given the: location on the sphere (in spherical or Cartesian) zy - plane rotation of the point up direction of the...- Sobe118
