Environment Shaders
- Environment_map_angular
- Maps a texture to a sphere. This mapping is also known as the "lollipop" projection and is analogous to the way in which a wrapper covers a spherical lollipop. The texture looks like a wrapper that has been unwrapped from a single point.
- Environment_map_ball
- Maps a texture to a sphere. The mapping corresponds directly to the view of the environment when a camera is pointed at a chrome ball. It is slightly unintuitive, but a chrome ball reflects the entire environment.
- Environment_map_cubic
- Maps a texture consisting of six squares to a cube. This mapping is one of the most common environment mappings.
- Environment_map_fisheye
- Corresponds directly to the results of taking a picture of an environment using a fisheye lens. Since the camera cannot see behind itself, fisheye mapping can only map at most half of the environment.
- Environment_map_spherical
- Maps a rectangular texture to a sphere. It is the mapping that can be obtained by pricking a sphere at the north and south poles, cutting a straight line from north to south pole, and laying the result out flat. This mapping is one of the most common environment mappings.
