Some tree

This is a very interesting idea to make vegetation. The grass (if it's indeed clouds) looks quite convincing. You sometimes have these soft fields of flowering grass. Can you elaborate on your procedure? I would guess you don't need much detail to produce the 'grain', hence it wouldn't take ages to render. Would it be possible to have a field of grass like this follow a hill?

I really like it ... cool stuff :)

Thanks!

One little crop against the sun:



@ Dune:
It is indeed clouds, if you doubt it, then maybe the method is useful.
Although the idea to make this image came from some problems with my trees leaves, I never intended to use clouds as real substitute.
I wanted it to look like clouds, and hence used at least medium quality settings.
I used 7 cloud layers (far mountains,hills, far bushes,two layers of "grass", the yellow "flowers" and the tree) and distance shaders, the planets surface is disabled.
I am sure there is some way to make the clouds follow the terrain, maybe dandelOs metaclouds could help. His grass-shader definitly rendered faster than my clouds.
I would rather have it look more like real clouds in the shape of a landscape than looking more "realistic"

Looks like you've discovered an effective watercolour technique using low sample (noisy) clouds. Great initiative.

I hope I realise I don't exist before I apparently die.

Nice work! Very inventive. 8)

Dune, Hetzen made some very nice clouds which are bound by a heightfield shader. http://forums.planetside.co.uk/index.php?topic=10582.0
And there was also an older thread by mhaze named 'clouds follow terrain' here too... Actually, the continuation thread was better... http://forums.planetside.co.uk/index.php?topic=5307.0

Thanks, Martin, re-found those posts... brain clicking... working on curly waves again now... maybe...

No clouds today- at least no green ones.
The clouds in the skye are by Matt, Altocumulus on page 8 of the cloud library

I had the first of three days of my final exams today
-it went well, and now its gone!
two to go.

This is a more postworked Pic.
I should do more postwork in future. Work is to hard.
I still had some problems with my leaves, but the outcome reminded me of a tree full of glowing bugs like I saw in bolivia.
Tried to emphasize the effect.



here is the unchanged version, I think the "bug" was sitting in my opacity image.

Hi Jan,

very interesting Point and Field of view ... and I really like the overall colours.

One thing that comes into my mind right now ... it looks like that you use some higher contrast settings, like I do.
Therefore you might want to try some extravagant colour settings inside the tree ,-)
