Rendering Aspects of Game Rendering

Rendering From Wikipedia: Rendering is the process of generating an image from a model. The model is a description of a 3D object typically containing geometry, viewpoint, texture, lighting and shading information.

Render Features Features/techniques associated with rendering include: shading — how the colour and brightness of a surface varies with lighting texture-mapping —applying detail to surfaces of a 3d mesh bump-mapping —simulating small-scale bumpiness on surfaces shadows — the effect of obstructing light soft shadows — varying darkness caused by partially obscured light sources reflection — mirror-like or highly glossy reflection transparency — transmission of light through solid objects translucency — highly scattered transmission of light through solid objects indirect illumination — surface illumination by light reflected off other surfaces, rather than directly from a light source (global illumination) depth of field — objects appear blurry when distance from the focal object motion blur — objects appear blurry due to high-speed relative motion non-photorealistic rendering — rendering of scenes in an artistic style, intended to look like a painting or drawing
