...This is not a strict port, since I just wanted the shadow mapping for another project I'm working on, so the fancy airplane animation is not included. I tried to build the classes so that they mirror the QML in terms of interface and functionality. It took me weeks to work this out, so I'm posting the code to help others. It's a shame that Qt3D is so lacking in documentation and example code. Tested against Qt 5.12.3 and Qt 5.15.5

This project is about an open source application to load and visualize Cal3d files in real time using OpenGL. For more advanced application, please download Vanda Engine: http://sourceforge.net/projects/vandaengine/ Please buy me a coffee: https://vanda3d.org/donate/ Thanks

...But since the game only uses OpenGL 1.0 the drawing code is outdated, but still things can be learned from the collision detection and other techniques. Some of the code is left in an unfinished/testing state. This game was a learning experiment for me, and the math used is tested until it works for the game. After using the science math by the book, there were still flaws that could make the player get stuck under certain conditions (since floating point is not exact), and the workarounds for this are just my own ideas. Have looked at the code for other 3D games and there are mostly the same problems around collision detection and "hacks" to get it to "work".

This is my first attempt at building a reusable framework for 3D applications (not an engine!), primarily for educational purpose and also because none of the already existing tools did satisfy me. No longer maintained.

Trixel is a Volumetric Raytracer that displays a solid world made out of cubes. Feel free to optimize it or add features, but please show me your result if you do so.
