GPU Pro 4

I received my copy of GPU Pro 4 this evening. At first glance, the following chapters "Tiled Forward Shading" and "Forward+: A Step Toward Film-Style Shading in Real Time" seems particularly interesting to me since that would be the lighting/shading approach i will be exploring for MageDx in the future. I can foresee a fun weekend ahead reading through the entire book. :)

Experimenting with Screen Space Local Reflections

Recently, i just completed Dead Space 3 (which is a pretty good game imo) and noticed that in the game, the reflections on the floors and walls seems to be utilizing Screen Space Local Reflections (SSLR), a rendering technique that first appeared in Crysis 2. SSLR, with its rather modest computation cost, provides real-time local reflections for all on-screen objects that would otherwise be prohibitively expensive to compute using traditional reflection rendering approaches. 

Over the weekend, i had some free time and motivation (finally!) to research and implement SSLR. My initial incomplete implementation of SSLR yields some nice results. Below is a pair of screenshots showing a scene with SSLR off/on. Stay tuned for more posts detailing my implementation of SSLR.
