|
* \subsection anisotoverview Overview
|
|
* The RpAnisot plugin is used to extend an \ref RwTexture with a maximum
|
|
* anisotropy value that will be used when a particular texture is drawn.
|
|
* When textured polygons are viewed nearly edge on, for example when looking
|
|
* dowm a road or a football pitch, distant pixels are not sampled very well
|
|
* by trilinear mipmapping and the texture looks smeary.
|
|
* Anisotropic sampling takes additional samples, resulting in sharper looking
|
|
* textures. Higher numbers of samples will produce better quality results but
|
|
* run slower, so should be used in moderation.
