Cogl.FogMode
The fog mode determines the equation used to calculate the fogging blend factor while fogging is enabled. The simplest Cogl.FogMode.linear mode determines f as:
|[ f = end - eye_distance / end - start ]|
Where eye_distance is the distance of the current fragment in eye coordinates from the origin.
Since 1.0
- FogMode.LINEAR
Calculates the fog blend factor as: |[ f = end - eye_distance / end - start ]|
- FogMode.EXPONENTIAL
Calculates the fog blend factor as: |[ f = e ^ -(density * eye_distance) ]|
- FogMode.EXPONENTIAL_SQUARED
Calculates the fog blend factor as: |[ f = e ^ -(density * eye_distance)^2 ]|
