3.1.3 Fog
- Method on
mglGraph
(C++, Python):void
Fog (float
d,float
dz=0.25
) - C function:
void
mgl_set_fog (HMGL
gr,float
d,float
dz) Function imitate a fog in the plot. Fog start from relative distance dz from view point and its density growths exponentially in depth. So that the fog influence is determined by law ~ 1-exp(-d*z). Here z is normalized to 1 depth of the plot. If value d=
0
then the fog is absent. See section Surface in fog sample, for sample code and picture.
