| Texture Minification Filter, Object Texture Minification Filter|
The texture minification filter element is a logic switch. If it is on, then the texels (i.e. texture pixels) are interpolated in a linear way, when the texture gets minified. Thus the texture is smoothed during the minification. If the switch is off, then the nearest pixel is used when drawing the minified texture. Thus sharp transitions between texels are visible on the texture being drawn. It is recommended to switch off the texture filtration when using a software driver, because the software filtration slows down the rendering process considerably.
If the faraway texture filter
switch is on, then the individual stages of the faraway textures are interpolated when the minified texture switch is on. When the minified texture switch is off the nearest stage of the faraway texture is used (the texture refining changes abruptly when the distance is changed).
The texture minification filter can be switched off in any object and texture stage separately by the object texture minification filter
command (for an active object
and an active stage
). If the texture minification filter
switch is off, then the texture minification filter is off in all objects, independently on the position of the switches for texture minification filter of the individual objects. The default setting of all switches is ON.
