Can any one suggest how I can produce REALISTIC versions of the following:

a) Sky with clouds.
b) An animated lake with moving water.
c) Pine trees (Maybe that can be animated to simulate blowing in the wind).
d) Short green grass.
e) A wheat field (That can be animated to simulate blowing in the wind).

Some or all of the above will be included in a 3 minute animation that will
be included on a new POV-Ray user site.

Please e-mail any suggestions to me and I will give you a mention on the
final animation credits.

Thanks in advance
Mickey

Skies.inc that comes with POV-Ray plus you can look at the following
tutorial. How to make it animated is left to the creative artist...

The POV-Ray objects collection has an include file called xtree.inc by
Remco DeKorte that makes a very realistic Pine tree.  Animation will again
be an exersize left to the creative artist

A Grass include file can be found here -

See answer to d. Change color and height of grass patches. Animating
this will be an exersize for...

There is a tutorial available on this subject -

Me? I've thought of animating the grasspatch, but I have no idea how to apply
consisent transformations to all those splines...

Hmm, if it uses MegaPOV, then you might be able to do something with 
vtransform(), vturbulence(), eval_pattern(), eval_pigment(), or any 
combination of these...

I suspect those are above my head, the problem is that grasspatch makes a
whole bunch of individual splines. I can move all of them uniformly, but
it probably won't look as good.

Actually, they are pretty simple:
    The first function, vtransform(), just applies a transform like 
scale, rotate, translate, matrix, or a sequence of these in a transform 
{} block to a point vector, moving it as they would an object.

    The vturbulence() function applies turbulence to a point vector. If 
you used this in the calculations for the grass positions, it would be 
the same as turbulating the grass.

    The eval_pattern() function takes a point vector and a pattern, and 
returns the value at that point(between 0 and 1 for most patterns, 
although there are exceptions).

    The eval_pigment() function does the same thing, except that it 
takes a pigment instead of a pattern and returns a rgb color vector. If 
you use position vectors in the color_map of the pigment and use the 
result of the function in your calculations for the grass, you could 
simulate things like waving grass.
Or you could use a combination of these, like vturbulence() with 
eval_pattern() controlling the amount of turbulence.

eval_pattern() scanning a ripples or waves pattern should make a good ripple
effect in the grass.
