Instancing in indigo

solo

Frederik,

I can model a component in SU and import straight into Vue6 xstream (it imports .skp) or I can use the tree/plant maker within the app, or use xfrog, onyx or tree generator trees and instance them. I can either duplicate, spread and smart drop them or I can paint them onto a terrain with the airbrush tool.
I can choose the scaling, assorted sizing, rotating and twisting too. I have collision control if I need it or allow overlapping, I have the fascillity to decrease the quality with distance leaving only the ones in the foreground in full detail.

Pretty cool.

20 000 trees, 208 million polygons, render time 7m24s

this is really impressive solo! in that short time!

I should definitely have a look at vue!

more please!!!

Amazing!

With best regards

thanks for the idea, Whaat. I messed arround with tree proxies and was soon at 10 000 instances. took an awfully long time to export

I pushed the use of proxies a bit further and wanted to find out, if nested proxies are possible (proxies within proxies)

well, obviously they are - what a wonderful tool! so you can create immensly detailed and complicated models and still be able to work fluently in SU? Great!

I then created some simple buildings (based on the same component), assembled these to building blocks and created a nice city area.
unfortunately my pc (Core2Duo @ 3.0 Ghz, 2 Gb Ram) can't cope with it anymore.

indigo, as well as the skindigo exporter seem to break down, if it gets too complicated (I wouldn't have expected differently).
now I would very much like to know, if the possible complexity depends on the power of the machine or on indigo itself.
I did a short test of a reduced city model (1/20 of it's original size). still took a long time to export...

it would be great if one of you guys with the incredibly powerful monster computers (like Coen) had a try. thus we knew, if it solely depends on the machine - and I have to save a lot of money to buy a new one

here is the file (the whole city with 1920 buildings is only 200 kb):

this is exceptional, any chance you could do a quick tut on this, inc. how you get it to instance in indigo, as i'm having mega trouble doing it, and also with finding out how to do it!

loving your work

It's quite easy.
I will take the example of a tree component.

Just make 2 components:

the high poly component named e.g 'tree'
the dummy component ( a box or a surface )named 'tree_dummy'

Copy around the dummy tree component as much as you like.
Hit render. You will see that the dummies will be rendered as full trees.

this is soooo amazing!!! we need that for SketchUp!!!

okay, finally gave it a go, VERY VERY impressed i must say.

used the drawhelix.rb, tube_along_a_path.rb, component_spray.rb and indigo renderer.

each one of these springs has nearly 3000 faces (sorry i didn't check the file size.) yet using all these rubys, and the instancing technique, i was able to produce the image below on my crappy work computer.

only left it to render for 10m 54s, with no settings changed (other than the spring material.)

I'm grinning from ear to ear!

a beautyful collection of springs. somehow they really seem to tell a story.

simply extend the ground plane beyond the screen borders and leave a high-res version of the image cook for some hours and we will have a real beautyful "still life", soon to be found in the tade...

that's really an impressive example of what is possibe with the combination of several rubies...

thank you plot, though really all the hard work was performed by those people who code these wonderful rubys, i just point and click.

oh just so you know, i have a high res, render (with the extended ground plane) cooking as we speak, going to let it run over night and i'll post it up tomorrow.

thanks again

cool - now I really have something to look forward to

I am way behind the curve with proxies. I understand the general concept and downloaded the city model to play with. Is the replacement of the cubes with the building models an automated process or do you have to remove the cubes and then reinsert the proxy one block at a time?

Does it have to do with switching the names of components?

remus

No need to replace the proxies (cubes) by hand, the rendering engine does it automatically. If i remeber correctly, its all to do wit the name for indigo.

plot-paris

you beat me to it, remus.

the only thing you have to do is to make this happen is to give the detailed component a name (for example "Component1") and then create a very simple component of about the same size and call it "Component1**_dummy**".

that's it. indigo will replace the "_dummy" with the "" component.

pav_3j

hey there plot,

got into work this morning and my computer had crashed over night and thus the render was not completed to a standard i would have hoped.

here's what i have though, think it rendered for about an hour.

going to try again today.

loving this instancing!

pav

plot-paris

well, thats a proper instancing - nice one pav. thanks a lot for posting.

that is unfortunate, that your computer crashed. that leads me to a question I wanted to ask for a long time:

how precisely does the resume function work and which files do you need to export out of SU to be able to do that?
I never succeeded in resuming a render (always got an error message).
would be such a cool thing. if your computer is unoccupied... just give him some old images to render them a bit further

pav_3j

yeah i had the same message when trying a resume. might just start to from the beginnning.

i must say that i am getting more impressed with the speed of indigo, especially with the instancing. i've not been as hot with my render practices recently, but now i have kerkythea, and indigo to mess about with i'm defo going to be hitting it up.
i had been using the latest version of artlantis, but as simple as it is to use (and as expensive as it was) i'm finding the functionality and variables in a league below these two free renderers.

oh well, guess i'll save for v-ray so i can compare that too.
