VR-based welding training system

One of the first project in Unity, made with a lot of love and passion

Features

  • Made by a team of 3 people in 2012, when Oculus DK1 has not been release yet

  • Magnetic fields based tracking system

  • Custom designed welding-base that supports flat, vertical, and horizontal orientation of the welding seam

Custom wrapper for Unity

Due to subtle type of movement during welding precise tracking system was crucial for the training system. At that time we chose Polhemus Patrior Magnetic tracking system. One of my task was to marry the dlls from the tracking system with Unity. I managed to write the wrapper for Unity and even sold it several times on the Unity Forum.

Technologies behind the welding seam

  • Marching cubes based mesh generation

  • Triplanar texture projection

  • Dynamic vertex color shader

  • HDR setup
