# Environment Mapping and Other Applications of World Projections

@article{Greene1986EnvironmentMA, title={Environment Mapping and Other Applications of World Projections}, author={Ned Greene}, journal={IEEE Computer Graphics and Applications}, year={1986}, volume={6}, pages={21-29} }

Various techniques have been developed that employ projections of the world as seen from a particular viewpoint. [] Key Method Surface shading and texture filtering are discussed in the context of environment mapping, and methods are presented for obtaining diffuse and specular surface illumination from prefiltered environment maps. Comparisons are made with ray tracing, noting that two problems with ray tracing¿obtaining diffuse reflection and antialiasing specular reflection¿can be handled effectively by…

### Real-time environment map interpolation

- Computer ScienceThird International Conference on Image and Graphics (ICIG'04)
- 2004

This paper presents an approach that sparsely samples environment maps of a moving object and rapidly interpolates them for high performance, and two techniques are introduced for fast environment map interpolation without computation of scene shading.

### Environment Mapping for Efficient Sampling of the Diffuse Interreflection

- Computer Science
- 1995

Environment mapping is introduced to reduce the amount of computations involved in tracing secondary rays during rendering, instead of tracing the secondary rays all through the scene, values are taken from the maps for the rays that would otherwise hit distant objects.

### Spherical environment maps for image-based rendering

- Computer ScienceDefense, Security, and Sensing

### Light field rendering

- Computer ScienceSIGGRAPH
- 1996

This paper describes a sampled representation for light fields that allows for both efficient creation and display of inward and outward looking views, and describes a compression system that is able to compress the light fields generated by more than a factor of 100:1 with very little loss of fidelity.
