Scatter Tests

Fewer, better fibres.

*ahem* Nick, please make sure nobody sees this on your screen while it's rendering...

Everybody would see it, as soon as you provide them with the option. The topic was the shape of the fibers, and it was improved indeed compared with the previous render :/

Hmm, I mean, it looks a little... uhh... just copy another one of those hairy balls next to it...

Thanks for proving inception can be done... plargh

I'm missing two points in one thread x_x'

BTW could someone paint decent beard maps for the infinite head ? like: density, length... colour ?

Oh rofl just got ya lyc oh lol woops. One point left.

Did a little more work on grass scattering and material:

I like it !

I like it !

Thanks. It's surprisingly difficult to make realistic grass.

DON'T TELL US ARCHVIZers!
Wonderful job Ono!

..have you found some spare time to think about the camera shift "abnormality" I pointed out some time ago?

What was that? Linky?

Did a little more work on grass scattering and material:

Looking cool! Is it possible to control density with BW textures? The way to get good, random grass in Blender is to give it a Group (list of objects) from which to pick objects to scatter. The more objects, the more random / natural it can look.

Can we get some ISL samples for this kind of stuff? Off on vacation for the next while, but will get back into the swing of things after that...

[StompinTom]

Would it be possible to get some of that scattering ISL code to play with? I'm keen to work past Blender particle export -> Indigo as it is very very slow

hello
I tried scatter function in animation with a static camera.
unfortunatly this is not always correct...
as you can see in this animation test, blocks scattered on the terrain have some vibrations du to variation's scatter function. the first part is correct, no vibration, the second part is vibrating...differences in scatter's result, of course the scatter settings are always the same, I run 6 sequences and got 3 sequences with differences
5 sec. Animation

instead of the camera if a world zero reference point was available for scatter generation, animation could be possible

[zeitmeister]

Yes, access would be awesome!


Cheers, zeiti

it works !!
including scatter function in animation with static camera is working if evenness is 0.0
so i put these values

Code: Select all

		<seed>1</seed>
		<view_culling>false</view_culling>
		<orient_normal>false</orient_normal>
		<scale_std_dev>0</scale_std_dev>
		<height_std_dev>0</height_std_dev>
		<evenness>0.0</evenness>

and render again the same previous vibrating sequence and all is fine
yesssssss EDIT : it's 98% perfect



if an option for world's zero point could be use for reference instead camera, moving camera in scattered environnement might be possible.

Edit2 : an other try with 2 scatters,

one with 6 protos using material restriction area function and second scatter with one object everywhere, it's 800x600 around 35spp per frame.

animation of the world around a satic camera :
<evenness>0</evenness>
<view_culling>false</view_culling>
but still some differences noticeable in the foreground
2 scatters in action :
one with 6 protos using material restriction area function and second scatter with one object everywhere, it's 800x600 around 51 spp (3 mn on my hardware, laptop i7 2.4GhZ) per frame. I denoised via photoshop.
