trial VS Panda3D

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.

Panda3D (MIT/C++) https://github.com/panda3d/panda3d

For open source 3d engines that use Python check out Panda3D or Ursina. They're both a blast to use and let you write your codd how you want.

Panda3D: Let's you make games with c++ and python. I don't think there is an "editor" or anything like that with this engine, but it does look like there have been some decent games made with it. Could be good for smaller games. Modified BSD License.

I know a lot of people recommend Godot because it's super good but if you want a more code oriented and batteries included engine I recommend Panda3D [0] it's open source, super mature (it's actually one of the oldest continously developed game engines), and can be used form Python and C++. Not sure why it's not more popular it's flexiable and super fun to use.

Some of the game engines we have now have photogrammetry technology built-in, meaning that developers can easily integrate it into their games. This allows for even more detailed and realistic environments to be created in 3D games. The most prominent being Unreal, Unity, and Lumberyard -- including new and beginner-friendly ones like Panda3D and Yahaha. All of these game engines have photogrammetry at their core to help developers create realistic 3D models and textures quickly and efficiently.

Make sure to provide your junior developers or any new members with the resources and tools they need to succeed. This could include coding books (The Self-Taught Programmer was my favorite before), online tutorials, or access to development tools and software. There are game engines available that can be a training ground for new devs, some of the game engines I’ve tried are Panda3D, GameMaker and Godot. I’ve also tried newer engines like Yahaha, but this one is pretty easy compared to other engines so there’s really not much of a challenge. The point is, no matter what resources and tools you provide, make sure they are tailored to the skill level of your junior developers.

...and there are some samples in the source https://github.com/panda3d/panda3d/tree/master/samples

It's not my project, but https://www.panda3d.org/ is to my knowledge the next best step after Unity and Unreal game engines. Unlike those, panda is open source and available for C++ and Python.
