parg
This is a C99 library with some basic stuff for bootstrapping a graphics engine. Currently it is tested against OpenGL 2.1 on OS X, and WebGL 1.0 via Emscripten.
The par library is a required submodule, so be sure to do this after cloning the repo:
$ git submodule update --init
The API is divided into modules, each of which has a single C file:
- token string-to-uint32 hashing, and a lookup table for uint32-to-string.
- asset unified way of loading buffers, shaders, and textures.
- buffer an untyped blob of memory that can live on the CPU or GPU.
- mesh triangle meshes and utilities for procedural geometry.
- texture thin wrapper around OpenGL texture objects.
- uniform thin wrapper around OpenGL shader uniforms.
- state thin wrapper around miscellaneous portions of the OpenGL state machine.
- varray an association of buffers with vertex attributes.
- draw thin wrapper around OpenGL draw calls.
- zcam simple map-style camera with basic zoom & pan controls.
How to Build for macOS
brew update
brew install cmake uncrustify glfw clang-format pkg-config
mkdir build ; cd build ; cmake .. ; make -j
You can then run a demo like this:
./trefoil
How to Build for WebGL on macOS
brew update
brew install cmake uncrustify glfw clang-format pkg-config emscripten
python emsetup.py
source aliases.sh
initjs && build
You can then run a demo like this:
build/trefoil

I'm currently using:
- glfw 3.3
- emscripten 1.36.5
