pbhnblog.ballif.euPart 4: 3D meshes and Marching CubesMotivation So far, we’ve simulated featureless, undulating orange grids, which I find boring. What’s really cool would be an animation of a droplet of water falling into a water surface, including all the splashing effects, like this: A quick search...Nov 23, 2025·9 min read
pbhnblog.ballif.euCUDA for Wave Simulation - Part 3: Efficient CUDANon-trivial CUDA The current snippet of code calling CUDA is: cuda_step<<< 1, 1 >>> This uses only one CUDA thread, and is probably extremely inefficient. To verify this, let’s add some way to time the program. I could use NVIDIA’s nsys, or just the...Aug 31, 2025·8 min read
pbhnblog.ballif.euPart 2: Basic CUDAThere’s a good first CUDA tutorial here: https://developer.nvidia.com/blog/even-easier-introduction-cuda/. Then there are the docs here: https://docs.nvidia.com/cuda/cuda-c-programming-guide/#. The docs describe three levels of the thread hierarchy —...Aug 17, 2025·6 min read
pbhnblog.ballif.euPart 1: OpenGLMotivation In this series of posts, I'll try to simulate waves on a GPU using CUDA. First, I'll describe the exact scope of the project. The goal is to implement some computational fluid dynamics method to solve some fluid dynamics problem - for now,...Aug 17, 2025·12 min read
