bramble VS procedural-gl-js

I've been looking into Nix a lot lately (but have yet to take the leap - I'll probably start with devshell)

But a couple of projects have come up lately that piqued my interest wrt syntax and alteratives (Since I am not sure about Scheme anymore than Nix (as a langauge) :-)

An alternative to Nix that uses Starlark (python syntax) instead of a purely functional programming language: https://github.com/maxmcd/bramble

I struggled to climb the steep learning curve of Nix/NixOS and wondered what it would be like with a more familiar (to me) syntax.

It's been very rewarding to write. I was able to implement some ideas from the initial Nix paper that aren't present in Nix. Nix is also quite dependent on the use of the /nix/store path, but I was able to allow a user to use almost any path for their build store without sacrificing on the potential for a shared build cache. I also want to have better native support for things like building docker images, among other features.

I'm currently implementing sandboxing and finalizing some of the build structure, but hoping it'll be usable sometime soon.

Nice writeup, I always like it when the shaders are highlighted like this. I got started in a similar way 7 years ago and have been making 3D terrains with THREE.js & WebGL since.

The real fun begins when you need to implement some sort of Level-of-Detail system and streaming in data to give the illusion of high detail everywhere without sacrificing performance.

Last year I released an open-source framework (https://github.com/felixpalmer/procedural-gl-js) for creating 3D terrains for web applications, you can see Uluru here: https://www.procedural.eu/map/?longitude=131.036&latitude=-2... (unfortunately the aerial imagery from our default provider isn't as high resolution as other places in Europe)

Great visualization and approach with compressing the tile data. Do you have a comparison of how much smaller the payload ends up being compared to simply sending PNG files?

I use PNGs to encode elevation data in my 3D mapping library (https://github.com/felixpalmer/procedural-gl-js/) and this does a pretty good job of compressing the data, for example in the ocean the PNG files are also very small as the image is mostly black. Different use case I now as your data is much more sparse, but I wonder how close the PNG compression would be compared to your approach.

Yeah, the React parts of this are very minimal. I'm not really sure what using it gets you, since it just manages a single div.

The _actual_ library that does all the work is here: https://github.com/felixpalmer/procedural-gl-js

- Tiny filesize means library is parsed fast. Package size is less than THREE.js thanks to code stripping

The imagery comes from the Orthofoto dataset on https://www.basemap.at/ - the actual texturing is done by the Procedural GL JS library https://github.com/felixpalmer/procedural-gl-js
