But... (always a but...)
One thing that's been bothering me with all your fern-images, is the lighting...
The shadows are too dark.
Try something like this:
//begin
#declaren main_light_location=<insert location here>;
light_source {
main_light_location
rgb 1
}
light_source {
main_light_location
rgb <.5,.4,.3>
shadowless
}
light_source {
-main_light_location
rgb <.4,.5,.9>
shadowless
}
//end
cu!

camera{location-z*3}#macro G(b,e)b+(e-b)*(C/50)#end#macro L(b,e,k,l)#local C=0
;#while(C<50)sphere{G(b,e),.1pigment{rgb G(k,l)}finish{ambient 1}}#local C=C+1
;#end#end L(y-x,y,x,x+y)L(y,-x-y,x+y,y)L(-x-y,-y,y,y+z)L(-y,y,y+z,x+y)L(0,x+y,

Hi,

Thanks.

I expected that :-)

> The shadows are too dark.
Yep. Pretty hard shadows since I haven't set up radiosity yet and don't use
any ambient at all. (Speed reasons, at least for the radiosity stuff). The
last image uses a area light (but only 3 x 3).

Ok, I'll try this as well. Since I have the fern as a file (116MB) it is
parsed within 6 minutes :-))
thanks for feedback,

Gosh!! :o) Well, pardon me if I missed something in previous threads but
wouldn't it be a good idea to reuse some leafs? I know you have coded a
good way to control details, but 116 MB is still .... *raise eyebrows* :o)
But good work!

Hi,
this is the result with your lighting. I had to remove the background plane
since it would have blocked the backlight.
Looks a bit washed out IMHO.
Next test will be with radiosity.

Hmmm. Hardly. The whole fern is a single mesh. Doesn't help to reuse
triangles, at least you have to move them to their proper place *gg*
> good way to control details, but 116 MB is still .... *raise eyebrows*
:o)
Well... it is large of course. On the other hand: the LOD settings are quite
young and not yet properly arranged. Additionally the number of triangles
per leaf isn't set up correctly yet. I think I can cut down the file size to
the half without loosing details (in the front).
And: don't forget that the main wings are 50cm in length and have more than
80 leaves each!
> But good work!
Thanks. As you know: it took long enough.

SY

no it wouldn't... it's a shadowless light_source, it doens't get blocked :)

I like it!

Will be much slower and the results won't be much different I think...

Aha? I must admit that I use shadowless lights rather seldom (not really
realistic). I thought it just doesn't cast shadows but can be hidden by
other objects. I didn't know that it shines -through- objects.... funny.

It's yours ;-)

Slower for sure.
What I can see up to now (1/3rd) doesn't really differ from your
version.....

to be complete:
this is the radiosity version.

The few differently colored leaves look still a bit strange, but apart
from that it looks good. Maybe try some more leaves halfway between the
standard and the dried ones.

I think the fern is looking quite nice.
it looks better with this lighting, BUT with lighting like this it would
look more like a showpiece in a museum than a real potted plant sitting
in a home.

Yes, of course. The lighting is very important and these posts are only
tests and concentrate on the model rather than on a nice scenery.
The final scene will cast some shadows in it, some parts will be lit
extremely by runrays..... we'll see.
thanks for feedback,
