The Compute Shader // Vulkan For Beginners #28

Auto-discovered

OGLDEV

Description

OGLDEV Vulkan For Beginners episode 28 on compute shaders that generate a texture sampled by a full-screen graphics pass. This URL is one tutorial in the series.

It reviews global versus local workgroups, queue selection with a WithCompute flag, and a ComputePipeline base class for modules, layouts, and dispatch. A TexGenComputePipeline writes a Shadertoy-style algorithm to a storage image; barriers then sync a FullScreenQuadPipeline that samples it. Covers storage-image descriptors, uniforms, RGBA UNORM usage, and one shared queue to avoid semaphore complexity.

For beginners already through graphics pipelines and descriptor sets in the series. Prior OpenGL compute helps but is not required.

Free on YouTube with reusable class structure for later compute demos. A working Vulkan setup is enough to follow.

Useful as a first template for compute dispatches that feed the graphics pipeline.

Believable Caustics Reflections (Alan Zucconi)
Believable Caustics Reflections is Alan Zucconi's September 2019 Unity blog post on faking pool-style ripple caustics without ray tracing, sparked by Florian Gelzenleuchter's popular shader GIF. One tileable texture is sampled twice in a Surface shader at different scales and scroll speeds, combined with min(), then tinted onto albedo with slight RGB UV offsets for dispersion. The walkthrough covers _ST tiling, _Time animation, HDR albedo above 1.0, and Post Processing Stack v2 bloom.

Custom Render Passes in Unity is Alexander Ameye's July 2021 ameye.dev note on URP ScriptableRendererFeature and ScriptableRenderPass boilerplate, heavily commented where Unity SRP documentation still feels sparse. The sample applies a two-pass box blur: blit camera color to a temporary buffer, blur vertically then horizontally, with adjustable strength and downsampling.
