What is environment mapping?
In the real world, at each point in a scene, light arrives from all directions (not just from a few point light sources).
Environment mapping is a scheme that improves on the mapping techniques of chrome and refraction mapping. It is useful because of the fact that in a reflective ...
Also called reflection mapping. ○ First proposed by Blinn and Newell 1976. ○ A cheap way to create reflections on curved.
Visual artifacts are common. □ Sphere mapping is view dependent. □ Acquisition of images non-trivial. □ Need fisheye lens. □ Or render from fisheye lens.
A mapping between the reflection vector and a circular texture. • Contains the whole environment around a point in a single.
Since environment maps represent directional informa- tion as a 2D texture, it is necessary to decide for a map- ping from directions to texture coordinates in ...
An "environment map" is a "360 deg" RGB image of a scene, defined on the unit sphere centered at some scene point. We denote it E(rx, ry, rz) where r is ...
