trial VS BabylonJS

Little Spark - made with Trial

The engine is called Trial. https://github.com/shirakumo/trial.

I don't know what the situation is like for 3D game programming in CL. Shinmera recently kickstarted a game but it's 2D I think and I don't know if his engine (https://github.com/Shirakumo/trial) does 3D. But regardless of what you're using, going into learning how to program while also trying to learn how to use the game engines available in the CL world will probably be a recipe for getting overwhelmed and discouraged. I'd recommend going through the Steve Losh post first and reading A Gentle Introduction to Symbolic Computation and/or Practical Common Lisp to get some solid general familiarity with using CL. Both are available online for free. You can also browse through the Cookbook: https://lispcookbook.github.io/cl-cookbook/

For graphics there's a lot of different variants and options. I use Trial, but that doesn't have any docs yet, I'm afraid.

Kandria and Eternia both are built on top of the game engine Trial, which I and a few others at Shirakumo have been working on for some years now. Trial itself makes use of a bunch of lower level libraries like cl-opengl, GLFW, pngload, harmony, etc. but a huge amount of the codebase was written by me. If you're interested in its development, I recommend hopping by the #shirakumo channel on the Freenode IRC network. I'd be happy to answer questions there!

A good way to do it is to keep a staging area of sorts that keeps track of the manually allocated objects and their state. When you allocate you batch all objects to allocate together and then execute the load in one go, updating the records in the staging area. Then, when you're ready to switch to a different scene or whatever, you diff the staging area against the current set of objects that need to be live and deallocate everything else in one go.

It's been around for a while, and we've featured it in the April 2019 and March 2022 Release Radars. It's also been in GitHub Game Bytes and on our latest episode of The Download. Yes, I'm talking about Babylon, the powerful web rendering engine for all kinds of graphics. The newest update includes support for basic Global Illumination, a highly requested feature. Read more about other cool new additions including Gaussian Splatting, Ragdoll physics, Procedural Geometry and all the breaking changes in the Babylon release notes.

Wow that site is super cool! So I see most of the 3D stuff is using canvas, maybe three.js or babylon.js or possibly pixi.js.

Sure; I've used [Phaser](https://phaser.io/) before for a game jam like project and I've heard of [PixiJS](https://pixijs.com/) and [Babylon.js](https://www.babylonjs.com/) as options too. I can't really give a good recommendation either way; Phaser was fun to just write TypeScript and see my game, but it felt like a toy compared to Unreal. I'm sure you could really push it to its limits though. You mentioned you know about LibGDX; I don't have experience with it, but it does seem like a viable option.

I’ve only messed around with it a bit, but https://www.babylonjs.com seems impressive
