Gimme GPU Geometry

Compute Shader Library for managing and searching for a massive amount of objects, by performing geometry operations in parallel on the GPU!

This compute shader library will let you rethink the need for 8k monitors, as the number of objects that can be handled with it when each SIMD processor on the GPU is used to the best of its abilities does not easily fit on a regular screen.

More than just handling entities in a grid, this package also allows you to make them interact with the environment by giving you the possibility to do raycasts, by enabling you to perform a massive amount of queries in parallel (e.g. for GPU Boids), or statically precalculating and storing nearest neighbors using 3D Voronoi Diagrams in various different forms.

The stuff you'll get:

  • 13 Sample Scenes
  • KD-Trees (Nearest Neighbor Search)
  • Voronoi Diagrams in 2D and 3D supporting different metrics and shapes:
    • Points
    • Lines
    • Triangles
  • GPU Grids for handling a million or more objects with ease
  • Intersection calculations acting as massive parallel raycasts for simple shapes (in 2D and 3D)
  • A lot of queries
  • A GPU Job System
  • 41 compute shaders (excluding additional ones in the sample scenes)
