Pixelate Filter in HDRP using Compute Shaders

In this article, we’ll complete the trifecta and port our Pixelate image filter to HDRP. If you haven’t yet, I recommend reading the first post first to understand the full

Pixelate Filter in URP using Compute Shaders

This article will use the pixelate image filter from the previous post but in URP, the Universal Render Pipeline. We’ll set up a ScriptableRendererFeature and ScriptableRenderPass to run the

Pixelate filter: post-processing in a compute shader

In this article, we explore post-processing by writing a pixelate filter using a compute shader. How does post-processing work? At its core, Post-processing, aka image processing or image filters,

Mesh Deformation in Unity

In this article, I explore mesh deformation using a custom vertex shader. Andy Saia’s GDC talk on mobile effects inspired this post. If you’re interested, I linked that talk at the end of

Volumetric Heat Diffusion for Automatic Mesh Skinning

I wanted to use the GPU-based mesh voxelizer we previously wrote to implement an automatic skinning algorithm. We’ll use a heat diffusion algorithm to radiate heat through the voxels to tie

GPU Mesh Voxelizer Part 5: Filling the inner voxels

In this article, we’ll fill the inside voxels of our voxelized mesh. Doing this will complete our GPU-based mesh voxelizer. To do this, we’ll implement the Möller-Trumbore algorithm for

GPU Mesh Voxelizer Part 4: Mesh Translation and Rotation

In this article, we continue developing our GPU-based mesh voxelizer. The previous posts in the series are available here: part1, part2, and part3. Previously our model had to be
