Requirements

  • NVIDIA GPU compatible with CUDA
  • The Cuda toolkit
  • CMake
  • Visual studio

Run the project (Windows)

mkdir build && cd build

cmake ..

Open the project collisions.sln with Visual Studio and execute it there.

Program arguments

These are the available arguments you can use:

1. Versions

  • -v 1 CPU Parallel grid collision detection algorithm (OpenMP)
  • -v 2 GPU Parallel grid collision detection algorithm (Cuda)

In some cases, the CPU version might be better than the GPU one (Not my case, AMD FX-6300 and GTX 960).

2. Time step

  • -t 0.02 The smaller the higher the precision but slower the simulation.

3. Maximum particle size

  • -s 15.0 Particles would have radius from 1 to 15 pixels.

4. Buckets per row

  • -b 10 This would make a uniform grid of 10 x 10 buckets/cells.

5. Bucket capacity

  • -c 1000 The maximum number of particles that can be in a bucket.

Example

.\collisions.exe -n 40000 -b 100 -c 5000 -s 5.0 -t 0.02
