today, i was experimenting with functions, trying to understand what functions are for and how i can use them. :-\
After reading some of the tutorials, clicking in the node network, doing some settings and after many many many test renders i got an render image and my first thought was "Ahhh ... what's that". It was not the result i want to get (i was looking for same typical dunes "waves" for a desert image). So you can see, I don't understand this functions really :(
perhaps for the most of you 'hight-levels' this will be nothing new, but i've been very suprised and i think it looks funny - like dry grass or an endless grain field - what do you think?
In this sample the base of all are the Snow shaders of Lucio http://forums.planetside.co.uk/index.php?topic=753.0 (http://forums.planetside.co.uk/index.php?topic=753.0). But i think, you can also use a normal surface shader.
Instead of white snow i used yellow sand in different colours (perhaps i should try it with several green colours).
The functions for the 'grass' you can see in the snapshot below:
The settings are:
constant vector 01: 1000 1000 1000
constant scalar 01: 800
displacement multiplier in 'Sand Basis': 1000
Camera position is very high! 3100m!
Render quality of the sample: 0.5
Render time (500x350 px): 1:13:35
This does look pretty good. I want to experiment.
Wow, nice work for sure. I've been trying to do this myself, and was successful, but it took ages to render, so I abondoned it.
Very good result, thanks for sharing.
Can you tell if there's any difference in how much RAM this takes up and how much RAM is used in a grass population? This could potentially be a good replacement for use in those scenes with billions of blades of grass.
It's a very interesting idea!
