4.1. RENDERINGAspects of Game Rendering
RENDERINGAspects 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
