I posted a few days ago a screenshot of the long shader ISA code produced by the RGA compiler for a single atan2() instruction. The post got quite a large engagement and it felt like a lot of peopl…

One of the things we often take for granted on GPUs is the idea of early Z testing. It’s the main reason why Z prepasses exist at all, and it’s one of the things that has allowed forward rendering to remain viable without being completely overwhelmed by pixel shader overdraw (instead it merely gets overwhelmed by quad overshading, but I digress)...

I've kept playing with shader programming and managed to export a trained neural network's weights as GLSL variable definitions. The code is ugly as hell as I've done a lot of quick experiments with it, and I went all-in with macros where functions would probably be better suited. I hope you still find it interesting.

Excluding neural network weights, the whole thing is ~300 lines of code and can run a few variations of a simple convolutional network.

Hi ! I've been working on this article for the past few days. It would mean a lot to me if you could provide some feedback.

It is about implementing a physico-chemical simulation as my first attempt to write a shader. The code is surprisingly simple and short (less than 100 lines). The "Prerequisite" and "Update rules" sections, however, may need some adjustments to make them clearer.

Thanks for reading
