GitHub - bcrusco/Forward-Plus-Renderer: GPU-based Forward+ renderer

The defining stage of the renderer is the light culling stage. Here, we split the screen into tiles, each 16 x 16 pixels in our implementation, and determine what lights are visible in each tile. We use a compute shader (available in OpenGL 4.3) to calculate which lights are visible. There are two implementations of this technique described in the paper, gather and scatter. We chose the gather app
