The light on the grass is simply fantastic!

Indeed? I would need to test how it looks back-lighted. What I did now
to the - basically - Poser textures, is add some transparency and a
small amount of back light diffuse. I did this also for the tree leaves
in the background.

The effect is of wet grass illuminated by the sun, and I like the
contrast with the shadow zone.
If you have time to waste, you can try to add a path.

Oh yes, great image, nice foam and foreground this time ;)

Beautiful. I am such a hack in comparison....
May I ask some technical questions?
The mountains in the distance (love the layers) -- How did you do that? It
doesn't look like a simple heightfield; maybe a hightfield on another? (or a
heightfield turned sideways towards the viewer?)
The trees (or vegitation) on the mountain foothills -- they look more 3d than
textured on it. Did you loop a trace() and place green objects there? What
sort of objects?
Similar question about the far trees across the misty valley -- how detailed did
you make them to have them come out looking like that? (Obviously, you don't
need to model them to the leaf level at this distance).
And the close grass -- I've tried to make it with a bunch of triangles. They
were all the same color, though. How do you get all the colors? You don't
model them individually, do you?
Thanks!

The author probably used some isosurface. Add to that some clever
texturing. Add a bit of turbulance to break the regularity of the base
pattern.

Not textures nut actual objects, probably some mesh.
Mesh are very effecient: One mesh can be placed thousands of times and
only reside in memory once. Add some random rotation, slight uneven
scalling mean that only 2 or 3 meshes can make a very beleivable forest.

Those don't need much detail. Some low triangle count meshes can do the
trick.

You can create grass patches as mesh proceduraly. Have a ground with
varying colouring, apply some pattern to the grass colour, maybe use
some short grass patches and some longer ones.

Of course.

The mountains consist of one single height_field made in GeoControl. It
is mirrored and copied a number of times to fill the panorama. The
layers are produced by a texture using a slope/altitude pattern.

The trees are one single POV-Tree object exported as mesh{}. There are
200,000 of them from the far background to the middle foreground. They
are traced on the combined heigh_fields and randomly rotated, scaled,
and textured to different green hues. Obviously, I first saved a file
with trace positions. You only have to do that once as it takes some
time to calculate; then you only need to include the file and read the
locations which is very fast.

Same tree, one single bunch of trees over the whole image ;-) As they
are instanced from one single mesh there is very little memory needed.

Individual grass patches are originally Poser props. There are eight of
them, textured and uv-mapped and exported as mesh2. Using the same
technique as for the trees, they are randomly chosen, rotated, scaled on
the foreground heigh_field. The latter has a basic slope pattern texture
to put some green under and between the grass patches.
