-
- ABSTRACT: 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.

-
- ABSTRACT: Generating images of texture mapped geometry requires
- projecting surfaces onto a two-dimensional screen. If this
- projection involves perspective, then a division must be performed
- at each pixel of the projected surface in order to correctly
- calculate texture map coordinates.
-
- We show how a simple extension to perspective-correct texture
- mapping can be used to create various lighting effects. These
- include arbitrary projection of two-dimensional images onto
- geometry, realistic spotlights, and generation of shadows using
- shadow maps. These effects are obtained in real time using
- hardware that performs correct texture mapping.

- ABSTRACT: General-purpose computer graphics computer workstation
- technology is rapidly displacing more traditional "black box"
- image processing solutions. One core computer graphics technology
- that is driving this trend is "texture mapping."
-
- In recent years, the technique of texture mapping has moved from
- the domain of software rendering systems to that of high
- performance general-purpose graphics workstation hardware. A
- graphics pipeline incorporating a texture mapping (image
- resampling) engine is a state-of-the-art geometric image
- transformation engine.
-
- Shown here is how an advanced form of texture mapping, called
- "projective texture", can be used to interactively perform a full
- range of traditional geometric image processing tasks as well as
- enabling a wide range of new techniques. These include arbitrary
- projection of two-dimensional images onto geometry, realistic
- lighting/transmission effects, and generation of shadows using
- shadow maps. These effects are obtained in real time using
- hardware that performs correct projective texture mapping.

- * Accelerated Volume Rendering and Tomographic Reconstruction Using
- Texture Mapping Hardware
- * compressed PostScript format
- * uncompressed PostScript
-
- ABSTRACT: Volume rendering and reconstruction centers around
- solving two related integral equations: a volume rendering
- integral (a generalized Radon transform) and a filtered
- backprojection integral (the inverse Radon transform). Both of
- these equations are of the same mathematical form and can be
- dimensionally decomposed and approximated using Riemann sums over
- a series of resampled images. When viewed as a form of texture
- mapping and frame buffer accumulation, enormous hardware enabled
- performance acceleration is possible.

- As of today, texture mapping is used in visual simulation and
- computer animation to reduce geometric complexity while enhancing
- realism. In this report, this common usage of the technology is
- extended by presenting application models of real-time texture
- mapping that solve a variety of visualization problems in the
- general technical and scientific world, opening new ways to
- represent and analyze large amounts of experimental or simulated
- data.
-
- The topics covered in this report are:
-
- * Abstract definition of the texture mapping concept
- * Visualization of properties on surfaces by color coding
- * Information filtering on surfaces
- * Real-time volume rendering concepts
- * Quality-enhanced surface rendering
