Unity Compute Shader Experiments: GPU Flocking - Duration: 2:01. Better resolutions previews: Swarm - Skull - I Love Unity - Skull Mesh - Upvote - Moving Skull - Close Up Boids Most parameters can be changed from Unity but are not updated while the simulation is running.All simulation related calculations are performed in the compute shader and the drawing of boids from the simulation information in the surface shader.

GPU powered boids with multiple implementations The C# script is responsible for calling methods to bind and init (set) parameters on the compute shader, run it, bind (set) boids information to the boids material (which uses the surface shader) and draw the boids mesh with material using GPU instancing.On my system 24 000 boids can be simulated at 30fps, but some exceptions are thrown unrelated to the simulation and caused by the beta version of unity, which hopefully will be fixed in the future. Boids are also affected by placeable forcefields and drag. Prey boids also seeks the nearest food while fleeing from nearby predators which pursues nearby prey. It contains several implementations to see how some compare to others, check out the different folders in Assets. Boids - Unity (Part 2): Optimized Boids On Unity Using Compute Shaders Lester Dela Cruz. Bitonic sorting on the other hand will average at 5k loop but still is slower, what's interesting it the fact that the bitonic sort does not seem to be the problem but the fact that each thread are accessing data at an offset instead at the beginning which means we have tons of cache miss on the GPU.

Unity 3D - AI Boids Flocking Algorithm Demo - Duration: 3:43. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

This project was made to learn from compute shaders and to have a reference for similar project.It seems my tests to optimize with different implementations failed and a brute for loop seems to be faster than any other method.GPU Flock for each boid will check against every other boids if it's in its range, so we got a stable 32k loop every frame.

Realtime boids simulation on GPU in Unity using compute shader.Realtime boids simulation (O(n^2)) on GPU in Unity (2018.1.0b8) using HLSL compute shader.The boids support the usual flocking behavior (separation, alignment, cohesion), staying in box bounds and maintaining a reasonable speed. Unity-GPU-Boids This project was made to learn from compute shaders and to have a reference for similar project. Prey boids also seeks the nearest food while fleeing from nearby predators which pursues nearby prey.

Check out This GPU Flocking system is a great way to learn about compute shaders and is quite inexpensive to run for a few thousands units since it offload the work to the GPU and there is no readback to the CPU. The boids support the usual flocking behavior (separation, alignment, cohesion), staying in box bounds and maintaining a reasonable speed. GPU powered boids with multiple implementations Boids are also affected by placeable forcefields and drag.
