Lighting Plugin for Sketchup

AdamB

This looks very promising Adam !!
What is the maximum face number in the present demo?

Hey thanks!

There isn't a hard limit in the demo. However, the demo has some crash bugs in it (now fixed internally), some incomplete features (eg support for Groups and Components which is now fixed internally) and more importantly used some Ruby methods to extract geometry information which is very slow.

It is this latter issue which means for larger models you have to wait an inordinate amount of time. We know how to fix this and it will be for the next released version.

Short answer is LightUp is aimed at large models.

Great!
Thanks
will be resolve feature for user with limited rights(non-admins...for windows)?

^^ Brings tears to my eyes...

If only SU would handle large models better... (nudge-nudge, wink-wink GSU developers)

Yes saw your post. I'm a bit unclear what the problem is here because LightUp isn't doing anything that requires special permissions. Its just some Ruby and some C++ running as a plug-in to Sketchup.

Any more info you can provide would be really appreciated. And I'll try and get a repro here.

Thanks.

what happened to the lightup forum? even logged in i cannot seem to find it?

I did some tests.
To get rid of the psychedelic effect, I had to either explode groups, or make sure there are no groups in groups or modify the group, like add a line in the group.
Adding a line at universal level did not correct the problem with the group.
Also, (to contribute);
There is light behind the feet where there shoud not. The dog looks above the platform.
Some faces of the "dog" are somewhat transparent; see the corner of the platform that should be hidden, for instance.
And edges appear somewhat chunkier then model really is. (maybe because of the unwanted transparancy)

The test model has 2 groups, the dog and the platform
The transparent effect is gone if I explode the group.

Well, I guess, this SCF is it now.

Edson

when someone sits on my work-place, I do to create 2 profiles(ohh...there were problems with mutanteded virus-bodies at flash-drives) and sometimes forget to switch to admin...so at "guest" i have always shutdowns of sketch...only when i try to start light simulation
all ruby-scripts work fine...

This is called "bleeding". Its because the platform continues under the feet of the dog so the interpolation incorrectly continues underneath too. You can fix it by changing the model to not go under the feet, also you can reduce it by increasing the Resolution of the lighting. I may add some code to LightUp to try and reduce the artefacts when it detects this.

Yes, the demo has a few bugs related to groups/components. Probably simplest to avoid using them for now by exploding the model.

... that is a LightUp component called an Irradiance Cache. It is discussed in the getting started document.
Adam

In my humble opinion, the Getting started document would be much more easier to view as a seperate PDF file.
It would much less intefere with the flow of work.

Edson, the LightUp website has a forum at http://www.light-up.co.uk/forum. Until we get the full version of LightUp out, I've not been able to devote as much time as I would like to it. But please feel free to post questions etc.

[And I haven't forgotten your request for a video showing exterior rendering in LightUp! ]

Interesting and noted. Thankyou.

BTW If you want the pdf it lives on Windows at:

and on Mac OSX at:

I have posted a video on youtube. LightUp-Bar

A test. It raised many questions.
One not resolved is why the sofa won't render properly. That checkered effect is wrong, the dark areas should not be.

Hi Adam,

I have loaded the program into pc, all going ok until I click on the tour tool - everything closes down? I'm on SU Pro. Is there anyway I can use this software?

Thanks

ilay7k

after playing with 3dvia shape(Thanks to Chris and Daniel for link and new gui of 7skipy ))
can you add support of dds-shader(Or something like symbiont from darksim) to lightUp for realistic materials? ...it's not so necessary but...i know that Pixero has some examples, i have

l.frisken

Will there ever be a freeware or at least cheaper version of this software that can encourage younger users like me to buy it rather than revert to the more complicated and time consuming rendering software?

remus

I.frisken, i think your best bet would be to send adam a PM and see what he says. He always struck me as quite a reasonable chap so he might be able to make you an offer.
