LightingAngle
LightingAngle
is an option for
ReliefPlot
and related functions which specifies the angle from which simulated illumination is taken to come.
MORE INFORMATION
Angles are measured in radians, counterclockwise from the positive
x
direction in the final image.
LightingAngle
->{
,
}
takes the effective illumination source to be oriented at angle
out of the image plane.
LightingAngle
->
is equivalent to
LightingAngle
->{
,
Pi
/4}
.
