Texture Maps
Textured materials use the same properties as above, and additionally define texture maps. Below is an example of a common material file. See the full wavefront file format reference for more details.

Texture map statements may also have option parameters (see full spec).

Famous quotes containing the words texture and/or maps:
“The verbal poetical texture of Shakespeare is the greatest the world has known, and is immensely superior to the structure of his plays as plays. With Shakespeare it is the metaphor that is the thing, not the play.”
—Vladimir Nabokov (1899–1977)
“And now good morrow to our waking souls,
Which watch not one another out of fear;
For love all love of other sights controls,
And makes one little room an everywhere.
Let sea-discoverers to new worlds have gone,
Let maps to other, worlds on worlds have shown,
Let us possess one world; each hath one, and is one.”
—John Donne (1572–1631)
