Level Set Ray Tracer
Level Set Ray Tracer
This application ray traces level sets by using the signed distance function to determine safe distances for rays to “leap” into the data grid. Snow is applied by letting particles fall downward in a 4D simplex noise field and applying a union operation where particles collide with the level set. The build-up of snow is rather slow for small particles, but smaller particles yield a finer grained build-up where individual unions are not visible after a while.
