Introducing FragCoord: My ultimate shader editing tool!

Looks really cool! One thing I always wished shadertoy had was a way to publish functions so you could share tonemap_aces and other people could then use it. Thought I'd mention in case interesting

Love this! #retrocomputing #coding

Unreal Engine 5.6 PCG - Ep 10 - Introduction to GPU - Texture YouTube video by Adrien Logut

Hey there! New #PCG video continuing the exploration of #GPU generation! We're targeting the texture sampling and add collisions on GPU. youtu.be/RrIYQjiDdho #UE5 #procedural

#Siggraph Work graph course is already online coburggraphicslab.github.io/workgraphs/

It's time to share the program for the 2025 Advances in Real-time Rendering in Games.

Check out all the details here: advances.realtimerendering.com/s2025/index....

and, of course, come attend the course live on Tuesday August 12 at SIGGRAPH in Vancouver!

Check out Range, my latest exploration of how far we can push a scene using Nanite Voxelization, 200 Trillion Polys Scattered with PCG on a 16k x 16k Resolution Houdini Landscape.

Using PCG with GPU Processing in Unreal Engine | Unreal Engine 5.6 Documentation | Epic Developer Community An introduction to Procedural Content Generation using GPU Execution and how to use it with your PCG workflow in Unreal Engine.

What a week. Unreal Engine 5.6 represents my 11th release in the 5 years I’ve been at Epic Games. For this release, my team focused on expanding PCG documentation, such as this great piece on using GPU generation w/ PCG: dev.epicgames.com/documentatio...

These pruned trees enable efficient evaluation of the SDF for rendering or discretization, resulting in >100x speedups for complex scenes compared to brute-force evaluation. Come to my talk next week for more details, or read the paper here: wbrbr.org/publications...

We often use discretization to approximate continuous laws of physics, but it also goes the other way:

You can use continuous equations to approximate the behavior of discrete systems!

Here we'll see how electrical circuits can be modeled using the Laplace equation Δφ=0. [1/n]

Houdini is a good reference for this. I found having sections of a large graph shift around while authoring starts making things unaligned / overlapping so isn't something I make use of personally.
