Lightsmark

Lightsmark application was designed to measure computer performance with next generation 3D engine.

Computers get faster, but rendering more polygons doesn't add value if lighting looks faked, so insiders know that the next big thing is proper lighting aka Realtime Global Illumination. Typical workloads in realtime rendering will shift. Lightsmark simulates it.

Global Illumination renders often take hours. Is your computer fast enough for realtime?

Before Lightsmark, realtime global illumination was limited to small scenes, small resolutions, small speeds, specially crafted scenes with handmade optimizations.

Lightsmark breaks all limits at once, running in reasonably sized scene (220000 triangles) in high resolution (1680x1050) at excellent speed (100-400fps). Lighting is computed fully automatically in original unmodified scene from 2007 game World of Padman, not tweaked for Lightsmark and with all sorts of geometrical difficulties, with extra rooms hidden below floor etc.

Here are some key features of "Lightsmark":

￭ realtime global illumination ￭ realtime penumbra shadows ￭ realtime color bleeding ￭ infinite light bounces ￭ fully dynamic HDR lighting ￭ 220000 triangles in scene ￭ 200-300 average fps (GF8800) ￭ fully moddable, data and source code in install directory
