Non-photorealistic Rendering. a longtime goal of graphics research has been to render a scene that is indistinguishable from a photograph of the scene. non-photorealistic rendering, or stylized depiction, is inspired by artistic styles. screen t0 t1 t2 t0 t1 t2 screen space shading spacememoization cache map()lookupreuse moving triangle shading domain rasterize ssID = map() map cache lookupptr = fetch(ssID)ptr? interpolate&store stor Don't. use outlines..

Lighting in computer graphics refers to the placement of lights in a scene to achieve some desired effect.. Lighting is very important part of an image synthesis.. It is used to create 3D effect by separating foreground from background.. Dan Baker. Founder, Oxide Games. Ashes of the Singularity. Nitrous Engine/Oxide Games.
