texture mapping technique used to simulate reflection or refraction
by modelling the background environment.
texture stores the appearance of the distant environment surrounding the
object. This is typically implemented as
a cubemap texture
, which consists of six images
arranged on the sides of a cube (like a skybox)
- In reflection
simulate the reflection of the light off the surface. Example:
Shiny guy in Terminator 2.
- In refraction
texture coordinates simulate the refraction of the light through the
