My first ever Steam game - Costa Verde Transport Department, a cozy traffic simulator - is OUT ON STEAM RIGHT NOW!

Thanks to everyone for the enormous support. Many things went wrong during the development process, but at least I learnt a lot and managed to release a game :)

Celebrated my bday in an Italian restaurant with an Italian owner

God bless Italian food (and wine)

Recently I made a demo project on WebGPU, rendering the classic Sponza scene with shadows and cloth & water simulation. My goal was mostly to learn WebGPU, test if it is production-ready, and have some fun on the way.

Here's are my thoughts on WebGPU and the project itself ⬇️

Triangular grids are a bit of a pain, but look how cute this little hexagonal tower looks!

I quickly hacked up the code so that walls are built with 4 floors in one go, and the window placing tool works with them with no changes required.

Folks, what's the proper way to do a least-squares solution for an underdetermined system? I'm doing gradient descent on (Ax-b)^2 + x^2 but it seems to converge to something that isn't a solution to Ax=b

New blog post: Demystifying multiple importance sampling

It is a simple thing that turns out to be confusing to a lot of us rendering engineers. I try to explain it in detail here with path-tracing examples!

Adding some environment sounds. I'm always impressed by how much sound design affects the overall experience!

I've completely remade my blog! Changed the design, improved the look of formulas, fixed broken links and typos, etc.

I was thinking of making a thread with my favourite articles, but that would be about a dozen of them, so I'll just drop the blog link here :)

My cozy traffic sim demo is available RIGHT NOW as part of Steam Next Fest! Almost a year of work and it's finally done - go try it, and don't forget to wishlist the game :)

I kinda like this wheat model, but it really doesn't look that good from a distance, even after I tweaked the outlines. I guess I need either some form of antialiasing, or use a lower LOD that doesn't alias that much.

So I was accumulating Monte Carlo samples using good old blending here, now I've switched to a compute shader explicitly blending into a storage texture and it is ~10x slower, interesting

The final pre-release devlog of my Cozy Traffic Simulation game is out! Covering 4 months of progress, including 2 months of burnout >_>

Enjoy! :)

Can't shake off the feeling that this terrain system could be used for so much more than just a silly road building game...

lisyarus, 6 months ago (edited 6 months ago) to random

To all players who've faced sound issues after playing the game for a while: I've identified the problem (a nuanced audio resampling bug in my audio mixing library), the fixed version is already on Steam!

As always, go try my first released game, I worked hard for almost a year to make it :)

Trying out different building designs

What am I working on here? Wrong answers only

Hmmm. Implemented the QR eigenvalue algorithm: works fine for symmetric matrices, but for a non-symmetric it returns a block-upper-triangular matrix (which is expected) and for some reason the corresponding vector in the U matrix fails to be an eigenvector.

So I made a thing that computes some forces, now need to figure out how to make these computations more reasonable

So... Lost my best friend a few days ago. After 6 months fighting with cancer, it finally took over.

RIP the funniest, the kindest, the loveliest, and the bravest of cats. I do miss you and I always will.

Apparently cppreference got hacked by some rust fanboys. Jesus, this attitude is exactly the reason I'm never going to use that language.

(jk, this is only one of the reasons)

Working with in-developement libraries has it's pros and cons.

Cons: wgpu-native doesn't support filtering float textures, and the MacOS distro is broken.

Pros: float filtering was implemented 6 days ago, the distro was fixed 2 days after I reported the bug.

New maps, freeplay mode, bugfixes and improvements: Costa Verde Transport Department releases tomorrow!

I presenteth you two perfectly white nearby boxes on a perfectly white plane lit by a perfectly white sky

Tbh I expected ambient occlusion to kick in much harder at the contact points

How do you compute the forces in a system of connected beams? I have no idea, so I tried the stupidest options and wrote a blog post about it. It has an interactive playground where you can test the algorithm yourself :)
