Dusted off my octahedral imposter demo for someone. Sprinkled in various trees from @quaternius.bsky.social
Should make them react to lighting properly and all that.

I’ve opened up many of the TSL exercises to everyone!
If you wanna try out some WebGPU shaders and fiddle with them, all in the browser.
Try an exercise and see if you can match the output.

A little followup to the last section: If you understand heuristics and admissibility, you can tweak A* to run much faster! If you're willing to sacrifice perfection, faster still.
Learn about it in my latest section on graph traversal.

Just added the next part of the graphs and data structures section, covering traversal and pathfinding!
Combined they're about 2.5 hours of new content, live now!

Fiddling around with octahedral imposters. The tree is actually just a sprite (intentionally low res).
Shader is doing all the work, and blending between frames. First pass, probably not super robust.

🧵 TSL is looking pretty awesome, but I got you covered until then.
I just hit publish on ~2 hours of new content to the course, covering how to dig into Three.js's internals, and we cap the project off with some terrain with erosion and scattering tricks.
Live in the course, so check it out!

Site’s basically done, just filling out a few last pieces for the course.
Had a minute, so I filled in trigger #3. A few people asked for rain. ☔
Good excuse to implement:
- Velocity-locked particles
- Positional audio
- A flexible animation system for cameras, lighting, and sound

The Three.js GameDev course will be available soon, mocking up a new site with a little demo on it.
Whipped up a trigger and animation system, which will eventually make their way into the course.
What should trigger #3 do?

You can build them on the GPU too, here's a few hundred thousand particles running with collision detection! This is just plain shaders, no webgpu or anything.

🚀 GPU particles can be difficult to understand—how do they work? If you want INSANELY high particle counts, they're the answer.
We'll start with the basics of GPGPU, laying the groundwork for GPU particles. This is just the beginning.
