This week, our Jon Baker will be presenting on "Implementing a Full Spectral Lens Sim." www.meetup.com/graphics-pro...

Here’s something!

wow, i never knew that you can postfix ~ with a user name in your unix-like os and your shell will expand that to that user's home directory

hi friends I'm very excited to announce Halfspace, my experimental cross-platform IDE for solid modeling with distance fields! This has been in progress since midway through last year, and it's finally "done enough" to make it more public.

I fell into the #unity3d #HDRP codebase again. Oops. I wrote a post about how the water currents were done at the time: rivers, cascades and vortices on an FFT ocean, and no feature written for any of them. If you are curious: anisb.github.io/2026/09/26/c...

It's a rainy day, and I haven't done anything in a while. So, I coded some tiny transition animations on the Workbench manipulators. Low effort, kind of fun.

Playing around with custom text rendering using SDFs. Not without limitations, but plenty good enough for a little side project. (late #screenshotsaturday post)

okay now we're talking

yay! i made my very first text renderer!! details: consumes 160MiB of memory is slow as hell no font metrics are taken into account each new character adds up an entire draw call #opengl #ttf

Made weird ahh synth

manifold

In Jai size of void is zero. Which means it is safe to dereference null because it reads 0 bytes from memory.

🔴🟡🔵 BIG WALK 🔴🟡🔵 Out now on Steam, Nintendo Switch 2, and PlayStation 5. Hooray!

a bit late to the party but i'll leave you to enjoy the final image i generated using my cpu-side rasterizer before i start to continue my gpu-side graphics programming journey #screenshotsaturday

am i daydreaming? (this is standard c99 and yes it does compile)

Experimenting with some mutations

software phong reflection w/ smooth shading

I'm close to finishing a major rework of how materials are baked in my engine. Rather than baking material properties directly, I now store a material palette per brick and bake blend weights. This means that material property blending is "deferred" to render-time, ... 1/

hand-wired perspective projection inside my software rasterizer

The Internet is truly dying. I don't wanna use Twitter, I don't wanna use GitHub, I don't wanna use YouTube, I don't wanna use any of the websites I used to use regularly. I have no place to go. The Internet feels like giant wasteland...

software depth test

gotta try this

barycentric color interpolation

software wireframe rasterization

More cloud render tweaking. Micro and macro scale test with different densities. #screenshotsaturday #rendering #vulkan #gamedev #indiedev #raymarching #sdf #voxels

another slightly older project i learned a TON of math from: a simple software renderer. every single pixel was calculated manually by me in python, no opengl geometry etc. didn't follow a guide, so i had to discover how to make 2D look 3D with guesswork/intuition and math resources. 280fps at 720p!

solid glass | hollow glass (notice how the two spheres at distance appear swapped when looking through the solid glass)

Made some progress on the water simulation for my relaxing sandbox game 🌳🏡Island Architect🏡🌳 I added some proper shading finally, and performance is much better, with a priority system for what to update each frame. In the video you can see how it reacts to terrain edits. #gamedev #indiegame

Inspired by @mmalex.bsky.social's dots experiments recently, tried to do some kind of "particle DOF" in the fluff renderer, effectively blowing out every particle's microparticles which gives a kind of uncanny effect that also melts my GPU with overdraw.

concave mirrors - interesting to see how it behaves with the source point inside/outside the focal distance (corresponds with the behavior here hyperphysics.phy-astr.gsu.edu/hbase/geoopt..., where there are different eq's based on location of source wrt the mirror surface)
