experimental 3d multiplayer game framework using simple data layer 2 and opengl
es3 in c++ 23
## intention
* multiplayer framework
* synchronized client input signals
* clients render at the rate of the slowest client
* server synchronizes clients signals
* grid of cells that partition world space
* update and collision detection of objects
* multithreaded
* game where most objects are visible on screen
* cull grid cells and objects to render within frustum _(todo)_
* importing blender exported `obj` files
* explore legacy opengl rendering
* intuitive programming of game objects and logic
* game code written in `src/application/`
* collision detection (that is "good enough" for games)
* sphere vs sphere
* sphere vs convex volume
* convex volume vs convex volume
* collision reaction
* sphere vs sphere
* sphere vs convex volume _(todo)_
* convex volume vs convex volume _(todo)_
## ubuntu packages used
* libgl-dev: opengl
* libglm-dev: opengl math
* libtbb-dev: parallel unsequenced `for_each`
* sdl2 related packages
* see `make.sh` for details
## howto run
* using script (recommended): `./make.sh && ./glos`
* using cmake: `mkdir build && cd build && cmake .. && make && cd .. && build/glos`
## sample game
* multiplayer enabled proof of concept
* `threaded_grid` must be `false` for deterministic behavior
* source in `src/application/` and `assets/`
* howto keys
* w: thrust
* a: rotate left
* d: rotate right
* j: fire
* k, l: cameras
* F1: print cells
* F2: collisions on/off (this will make clients out-of-sync)
* F3: render on/off
* F4: cycle through shaders
* F5: render normals on/off
* F6: render bounding spheres on/off
* F7: hud on/off
* F8: render grid cells on/off
* F9: print current shader info
