Hum... I don't have a global solution, but you may set a color for each vertex
with something lile :
color = (highColor - lowColor) * ((altitude - minAltitude) / maxAltitude) +
lowColor;
I apologize but I am still inexperienced.
I have a HeightField associated to shapeDrawable (this because if I use
Locator and GeometryTechnique I succeed in visualizing the alone ground
"GEOCENTRIC"),
therefore if I use
shapeDrawable - > setColor (Vec4);
I don't know whether to plan the values of the Vec4 with the formula
that you have sent me
besides of what type it is color?

You can allso do it in HSL coordinates (instead of RGB).

Hi!
does a way exists to color from the tallest altitude of a ground to the
lowest with gradations of color?
thanks
Aurora
