Hey there!
I just released my first article: "Graphics Programming - Where to Start"
https://t.co/IKZUTa5Os3

It's aimed towards new graphics programmers that want resources that are in my opinion the best when starting out with graphics.
Hopefully it can be of help to some :)

“Atan” tied for the 2025 BAFTA Student Award for Games. The game was created by Tom Baas, Jakub Petr, Stefan Pijnacker, Ketlin Riks, Lisette Van Den Dolder from Breda University of Applied Sciences in the Netherlands.

Hey there, I decided to write a "Quick-Reference Guide" to DirectX 12 resources.
It discusses some of the key topics and terminology of DX12 resources. Mainly intended for people new to the API or wanting a refresher.

@Pjbomb2 Thank you! At the moment I'm using ACES Filmic, I should probably add some more so I can switch between.

[Stefan Pijnacker @StefanPijnacker]

Did some work iterating materials & model loading for my path tracer. Quite happy with this one!
Building test scenes is starting to be fun.

[Stefan Pijnacker @StefanPijnacker]

@dmikis They are from https://t.co/WKLXk8hRi8 @polyhaven! Great site for free environment maps and realistic looking models.

[Stefan Pijnacker @StefanPijnacker]

Started working again on my renderer that uses DirectX Ray Tracing. Making good progress right now.

Gonna do some more modern techniques soon together with supporting quality settings.

[Stefan Pijnacker @StefanPijnacker]

Did a overhaul of the material pipeline, have some more control now.
Next up is improving the framework and trying different camera models.

Part 2 of 'Compute with DirectX 12' is now out!
Learn about UAVs, creating compute pipelines and running your first compute shader.
https://t.co/Z4jbfKwCum

The final part where we will make an interactive particle simulation will be out soon.

[Stefan Pijnacker @StefanPijnacker]

@icauroboros Thank you!
I'm not a webdev so I decided to use Wordpress as the platform (not the free option but through a host).

Then found a theme called 'Blogus' and modified the theme a lot through the CSS files until I got something I liked.

[Stefan Pijnacker @StefanPijnacker]

Hey there! I started a new article series on how to write compute shaders with DirectX 12.

The first chapter discusses the theory of compute which is mostly applicable for any Graphics API or engine.
https://t.co/0HQixLz8Yw

[Stefan Pijnacker @StefanPijnacker]

This series is aimed towards people completely new to the topic. I myself found the topic daunting at first so I wanted to write a more introductory series for others to use.

The next article(s) will be about the DirectX backend and how to write a simple particle simulation!

[Stefan Pijnacker @StefanPijnacker]

Thanks for posting about our game!

@alexanderameye I followed this guide by Nvidia, which also comes with a few helpers classes that help a lot when you are new to the API.
The tutorial shows ray tracing but with some extra shader code you can quite quickly turn it into a path tracer.

Further progress with materials. Dielectrics are in and specularity can now be tweaked per instance.

Onwards to microfacet.

[Stefan Pijnacker @StefanPijnacker]

@alexanderameye GPU, I'm playing around with DXR for the first time.
So far I can definitely recommend it :)

It comes with its own built-in systems for creating BLAS/TLAS. And you get to implement your own ray/path tracing techniques within a few different shaders.

[Stefan Pijnacker @StefanPijnacker]

@j_bikker At the moment just the diffuse BRDF and a pure specular one.
Currently working dielectrics so I can move onto Microfacet :)

[Stefan Pijnacker @StefanPijnacker]

Another step done, I now have editor controls and I've per instance data!

Now onto materials and variance reduction
