Fog

Fog - setup of fog (depth cueing)

Fog ( off | exp | exp2 | linear ) expr expr expr

Set fog mode and parameters. The first argument selects the mode (off, exponential, squared exponential, linear). The second argument selects the density for both kinds of exponential fog. The third and fourth argument give the start and end distance for linear fog.

Negative values for any of the numerical arguments will leave the value unchanged, this is useful for changing only one value if the command is put on a slider.

Not all fog modes are supported on all hardware.

EXAMPLE
