Boaster is a software rasterizer written in C, for the heck of it

Build with make:

make

Boaster requires POSIX API's to be present. This means that Windows is not supported. However, WSL is supported.

Feel free to issue a PR to port Boaster to Windows or other platforms!

Boaster is made up of multiple modules. Each module compiles to a static library, which you can link against:

-lboaster -lboastmath -lboastgl

Before rendering with Boaster, you need to create a context by specifying a configuration:

boaster_config_t config = {
    .raster_mode = THREADED,
    .num_threads = -1
};

boaster_context_t *context = boaster_context_create(config);

Once this is done, you can use this context to render. For rendering, a draw call must be specified, which can then be submitted to the renderer:

boaster_draw_call_t draw_call = {
    .vertex_shader = pass_through_vertex_shader,
    .input_format = &format,
    .transform_format = &format,
    .pixel_shader = pixel_shader,
    .vertex_buffer = vertex_buffer,
    .target_image = image
};

boaster_render(context, draw_call);

Boaster comes with multiple sample applications, which can be found in the root or in the parrotdemo folder:

• ./out/main
• ./out/glmain
• ./out/executor
• ./parrotdemo/out/parrot
  • Must be run from ./parrotdemo
  • This sample contains multiple animations
  • The animation can be specified as a command line parameter
  • Available animations ( under ./parrotdemo/data/anim ): parrot, shiftcube

NOTE: From WSL, specify the display to use: DISPLAY=:0 ./out/glmain
