A tutorial can be found here. Additionally, please reference the demo, and read the function documentation in termgl.h for more details.
You can compile termgl.c as you would any other C source file. You can also compile it as a shared library libtermgl.so by calling make shared. To install the shared library, sudo make install.
To enable 3D functionality, define TERMGL3D or use the -DTERMGL3D compiler flag.
To enable utility functions, define TERMGLUTIL or use the -DTERMGLUTIL compiler flag.
To disable helper functions for vector math and shaders, define TERMGL_MINIMAL or use the -DTERMGL_MINIMAL compiler flag.
To use TermGL in C++, compile it as a shared library and link against the libtermgl.so file. The termgl.h header can be included from C++ files.
To compile a demo program, run make demo, creating the termgl_demo binary.
A demo program can be found at termgl_demo.c.
