Cosa (chi) è texture mapping - definizione


Texture mapping         
  • For rectangular objects, especially when perpendicular to the view, linearly interpolating across a quad can give a superior affine result versus the same rectangle split into two affine triangles.
  • Examples of [[multitexturing]]:<br/>1:&nbsp;Untextured sphere, 2:&nbsp;Texture and bump maps, 3:&nbsp;Texture map only, 4:&nbsp;Opacity and texture maps
  • [[Doom engine]] did not permit ramped floors or slanted walls. This requires perspective correction only once per each horizontal or vertical span, rather than per-pixel.
  • Because affine texture mapping does not take into account the depth information about a polygon's vertices, where the polygon is not perpendicular to the viewer, it produces a noticeable defect, especially when rasterized as triangles.
  • Mapping a two-dimensional texture onto a 3D model
  • Screen space sub division techniques. Top left: Quake-like, top right: bilinear, bottom left: const-z

Texture mapping is a method for defining high frequency detail, surface texture, or color information on a computer-generated graphic or 3D model. The original technique was pioneered by Edwin Catmull in 1974.

TERM
Texture-mapping unit; Texture mapping units; Texture samplers
In computer graphics, a texture mapping unit (TMU) is a component in modern graphics processing units (GPUs). They are able to rotate, resize, and distort a bitmap image to be placed onto an arbitrary plane of a given 3D model as a texture, in a process called texture mapping.
