I think you can follow these steps to get the requisite solution to your problem: -
- Get Surface object for the desired surface.
- Use Surface::GetClosestPointOn() to get the point closest to the surface from the point you want to check.
- If the resulted point from Step 2 is same as the point you wanted to check then the point is inside the Surface.
Hope it helps!!!
all right, it works very well,
Thank you very much!
