For quite a while I've been working on a Fast Fourier Transform based ocean simulation in my render engine.
Whilst there is still a lot to work on, I'm excited to see the result once I've added IBL to this renderer.

If ever you feel like your code is Real Dumb and you'll never get into graphics, please take a look at my very first OpenGL project, which I recently unearthed on an old drive. It is indeed Real Dumb, and yet I persisted. You can too!

messing with this again, converted to a forward approach... it's more efficient at resolving the caustics, but I haven't figured out what to do for the artifacts where it clips in bright areas and the aliasing patterns that happen near the refractive surfaces... something to do with the line drawing

The Vulkan porting is complete 🎉 The last missing piece was the primordial raster renderer, which I am not sure why I keep around :)
All in all, it wasn't nearly as hard as I thought it would be.

More experiments with a fractal with very good geometry for representing pipes - three copies with different numbers of iterations for the sections of different material, doing like a pvc-pipe looking thing, with the other pipes done in a color constant for iron that I found and gold metallic accent

A thread full of nothing but The Last of Us part I environment photos. This game is incredibly gorgeous. Really impressive what they achieved here without ray tracing. Would love to see a long GDC talk or smth about how they made this game. There will already be posts below but I will add more.

Thanks to github.com/syoyo/tinygltf,
my CPU path tracer now supports GLTF mesh rendering! 🥳
Here are both of my renders of the Stanford Bunny (~75k triangles) with diffuse white and dielectric glass materials.

Finally, I’ve completed implementing all the concepts from the book. As promised, here are the renders of all the scenes from this book.

Put this off for too long, added hot reload of shaders. Super useful for debugging, using it here to shut off albedo to see indirect lighting in isolation and then preview UVs. Fairly easy to support since everything is done through a single shader and takes less than a second to recompile.

A few years ago I started implementing a 3d editor as a hobby project, prosaically named "Workbench". I dedicated a few hours to it most weeks, sometimes with months-long pauses. This is how it started and how it's going.

Following a single light path around twisty corridor.
By the way, the viewport is rendered integrating those long paths.

For the past few months, I've been learning and implementing the "Ray Tracing The Next Week" Book. I'm almost done with all the concepts. Soon, I'll post more renders. Meanwhile, here's my first ever render of the Cornell Box.

Instead of copying old posts from The Other Site, I will post my blog interplayoflight.wordpress.com in case anyone finds anything interesting in there. There is no theme, I blog about whatever shiny I tinker with, although there are quite a few posts on compute shader raytracing with homemade BVHs.

Graphics moved to BlueSky? Great!
While I work on the initial release of a fast, "C-with-classes", single-file BVH-builder / optimizer library, may I perhaps amuse you with some reading material on the subject:

Comes with a github repo too!
