Texture Filter Selectors

A drawing engine may support a texture mapping filter mode that determines how a drawing engine performs texture mapping. You specify an engine's texture filter by assigning a value to its kQATag_TextureFilter state variable. The default value of this variable for a drawing engine that supports texture mapping is kQATextureFilter_Fast.

#define kQATextureFilter_Fast          0
#define kQATextureFilter_Mid           1
#define kQATextureFilter_Best          2

Constant descriptions

kQATextureFilter_Fast

The drawing engine performs whatever level of texture filtering it can do with no speed penalty. This often means that no texture filtering is performed.

kQATextureFilter_Mid

The drawing engine performs a medium level of texture filtering. You should use this texture mapping filter mode when you want to perform texture mapping interactively.

kQATextureFilter_Best

The drawing engine performs the highest level of texture filtering it can. This mode may be unsuitable for interactive rendering.
