Howdy all !

    I have a question about the wave and ripple patterns that
are used in POV-Ray. It is evident that both use a concentric
method of implementation. That is to say they form like drop
rings in a pond.

    This is great for modeling fish ponds and swimming
pools but really makes it difficult to accurately model straight
line waves as would be produced by a boat or the typical
wave/swell pattern in the ocean. Certainly you can argue that
the ocean has a multitude of cross patterns and I won't argue
with you. But there have been days when I was out fishing
on the ocean and the swells were very smooth and seemingly
very straight.

    Is there a wave form now available in Pov that I have missed
that will allow a straight sine wave type pattern ?
    I checked the docs and if it's in there I somehow missed it.

If it's not now available should it be added ?

Would it be difficult to implement a normal pattern like this ?

See below for a list of supported pattern types I compiled from
the docs.

Seeking your answers, impressions, and opinions on this topic.

This list contains what I believe are all 25 wave forms and
normal/pigment patterns available in POV-Ray.

Have I missed any ?

Patterns List:
Agate     Checker   Hexagon   Quilted   Spiral2
Average  Crackle   Leopard   Radial    Spotted
Bozo      Dents     Mandel    Ripples   Waves
Brick     Gradient  Marble    Scalloped Wood
Bumps     Granite   Onion     Spiral1   Wrinkles

Thanks

Ken
