In an attempt to write something about that feature, I noticed strange
behaviour of the global_settings number_of_waves parameter.
#include "colors.inc"
camera {location <3,4,3>*4 direction z*2 look_at <0,0,0>}
plane {y,0 pigment {waves color_map {[0 YellowGreen][1 OrangeRed]}}}
global_settings {number_of_waves 12} //default is 10
light_source {<400,500,300> White*1.5 rotate y*50}
This simple scene shows very different results from one compile
to another. Official POV-Ray works as expected, but any MegaPOV
I tried acts differently (MP7, POVMan, and MLPov), giving different
result from one render to another, sometimes plain color, often
with noticeable plateaus in the waves.
Fabien.
