Description:


    “ToyShop” demonstrates state-of-the-art, real-time rendering on consumer graphics cards, such as ATI Radeon X1800. A variety of high-end techniques were designed with the sole purpose of creating an immersive, detail-rich, real-time environment. And while these methods surpass convention, they are implemented efficiently within the current specs of the most cutting-edge, popular videogame engines.

    One of these complex techniques is parallax-occlusion map-ping, a per-pixel ray-tracing algorithm for inverse-displacement mapping with dynamic lighting, soft shadows, self-occlusions, and motion parallax for rendering complex surface details with low polygonal meshes. A novel post-processing rain effect was developed to simulate multiple layers of raindrops with a com-positing pass over the rendered scene. The rain illumination is computed by combining water-to-air refraction for individual rain-drops, a Fresnel effect, and reflections due to surrounding light sources.

    Physics-based particle systems with stretched normal mapped quads generated raindrops falling off objects, complete with the illusion of motion blur. The illumination from the lightning system accurately simulated refraction and reflection of the droplets, adding further realism to the scene. An offline raindrop simulation system was adapted to the GPU to simulate and render water droplets trickling down glass panes in real time.
