	    Texture Mapping as a Fundamental Drawing Primitive

	Texture mapping has traditionally been used to add realism to
	computer graphics images.  In recent years, this technique has
	moved from the domain of software rendering systems to that of
	high performance graphics hardware.

	But texture mapping hardware can be used for many more 
	applications than simply applying diffuse patterns to polygons.

	We survey applications of texture mapping including simple 
	texture mapping, projective textures, and image warping.  We 
	then describe texture mapping techniques for drawing 
	anti-aliased lines, air-brushes, and anti-aliased text.  Next 
	we show how texture mapping may be used as a fundamental 
	graphics primitive for volume rendering, environment mapping, 
	color interpolation, contouring, and many other applications.
