How to spawn objects on a restricted sphere surface relative to camera?

Questions & Answers

Hello everyone,

I’m trying to spawn targets at random positions relative to my camera with certain restrictions, however I’m having plenty of trouble getting the transformations right.

How can I spawn an object at some distance D from my camera with

  1. A random horizontal angle offset
    from my current orientation between
    [-hA, hA] where a horizontal offset
    would correspond to moving the mouse
    left/right.
  2. A random vertical angle
    between [-vA, vA] where vertical
    angle would correspond to moving the
    mouse up/down.

Thanks,
Tom.

look up spherical-to-cartesian conversion. it’s pretty straight forward.

lmk if you can’t find something that works for you.
