Panda3D VS OpenSceneGraph

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.

I started in 2001 with OpenSceneGraph which made extensive use of intrusive pointers. This was 10 years before C++11 note. That codebase continues to be relevant and as performing as ever.

browse github and try to contribute. I started with OpenSceneGraph

I have been using OpenSceneGraph for over 20 years. It is used in the military a lot and I myself have seen it used to simulate war scenarios with realtime data aboard of a command-and-control center of a battleship.

Speed Dreams: It is a fork of TORCS, and was born as the need to include many more functions to the latter. In Speed Dreams the menus would be completely redesigned, adding many more options and making them much more intuitive; the game acquired dynamic time, improvements in reflections, career mode, a new simulation mode and multi threading. Over time many more options were implemented, such as local multiplayer mode, Force Feedback, and of course more and better cars and tracks, a new and more powerfull graphic engine (OpenSceneGraph) among other things, making it a much more complete game than its predecessor. They recently they have presented version 2.2.3. You can also install it in AppImage and Flatpak format.

Here is an example: https://github.com/openscenegraph/OpenSceneGraph/blob/master/examples/osgsimplegl3/osgsimplegl3.cpp

openscenegraph (mainly focuses on graphics, used by openmw for example)

Is not little, is very complex open source racing simulator. There are a lot of cars, categories, tracks. The physics has a lot of work . About the graphics, the devs are working on change the graphic engine to OpenSceneGraph, that actually works, but needs much more polishing.

I love Godot for a complete game engine. For just the renderer you could consider http://www.openscenegraph.org
