The idea is to:
- Visualise the half of the sphere based on perpendicular (red arrow) to the plane-like 3DMesh (rotate sphere it to the correct side)
- Generate Million of points on this sphere (no need to visualise them if this is not possible due to performance issues)
The problem is:
- Can not rotate “visual sphere” to the correct direction (rotation.copy can not be used because 3DMesh is always with 0 rotation) and can not find how to build this red perpendicular as no face normal can be used (I guess?).
- Don’t have a glue how to generate points in other way as I’ve presented in Live example… Vertices of “Visual sphere” can not be used as there is a need to have millions of points (with angle 1 minute of arc at the sphere)
Please, if anyone know how to solve any of this questions - provide your help.
I am really appreciating your time.
