Fog drawing information for use in GLKit rendering effects.
- iOS 5.0+
- macOS 10.8+
- tvOS 9.0+
These properties are specifically designed to mimic the fog calculations provided by OpenGL ES 1.1.
When fog is enabled, the fog component is calculated and clamped to a range from
1.0. Then, the fog value is used as a blending factor between the computed fragment color and the fog color.
Choosing the Fog Mode
var mode: GLint
The algorithm used to compute the density of the fog applied to the fragment color.
var start: GLfloat
The minimum distance in eye coordinates before fog is applied to the fragment color.
var end: GLfloat
The distance in eye coordinates where fog completely covers the color fragment.
A mode that describes how the fog component is calculated for the fragment.
