The ColorSweep 
Node
Example file burntCheese.smls is the same
as twoSineTugs.smls with a ColorSweep
node added. The ColorSweep node is set up to USE the land Part
node.
This simply means the ColorSweep node is set up to color the Part
land. The ColorSweep node is set to a straight
vertical (default orientation) color sweep
from 1 1 0 (yellow) to 1 .5 0 (orange) with a distance
of 7.5 meters between the colors. In the 3d
window we should now see an image of nearly burnt cheese on toast, an image
I have been trying to achieve for most of my life.
The ColorSweep node has 4 different modes of operation, straight,
mirror,
cylindrical and spherical but
for the time being, only straight and spherical
work.
sphericalColorSweep.smls is the same as
burntCheese.smls with another ColorSweep
node added set up to operaste in spherical
mode. The second colorSweep node is located at -39 0 40 and starting from
the center of the sphere with the color .5
.5 1 (light blue) moving out to a distance of 15 meters with this same
color and for the last 10 meters it is set
to fade out to yellow the same color as the
background.
twoSphericalColorSweep.smls is the same as sphericalColorSweep.smls with another spherical color sweep added located at -12.5 0 55.
There is a problem whith the color sweep fading out to yellow where
it crosses over into blue from the previous color sweep
Example twoSphericalColorSweepOpacity.smls solves this problem by instead of fading the color out to yellow for the last 10 meters, it has all 3 colors set to light blue but has the opacity field set to 0 for the last 10 meters. This results in the light blue color for the last 10 meters blending in with what ever the background color is.
And there we have it, land for a world that is made from a few simple techniques. We can of course make it more complex by adding more sine tugs and more spherical color sweeps. This tutorial is complete however for showing how to do this. It should now be possible for anyone to experiment with endless combinations of different values.
