Sure TIG. As shown in the video, its just an extension that opens a window so that when you execute Ruby:
DevLog.info("Hello world")
It shows in the log window. You can filter on log level and there are:
DevLog.warn("oo, something might be bad")
DevLog.error("oo, this is an error")
DevLog.fatal("oo, I cannot continue")
When you close SketchUp, the entire log file is saved to %Temp%
USP: Its around 4000x faster than puts
Hi,
DevLog v1.0 is a high performance logging extension for SketchUp. Its built from the ground up to be very fast - currently can handle around 2,000,000 log lines per second. I built it because puts really isn't made to handle lots of logging that you often need when debugging during development.
RBZ attached below. Let me know your thoughts!
Here is a short vid explaining a bit more::

RBZ installer attached
To install LightUp for older versions of SketchUp without .rbz Extension support, you'll need to:
LightUp supports SketchUp 8,SketchUp 2013, SketchUp 2014, SketchUp 2015, SketchUp 2016
Back in 2010 when LightUp was first launched, SketchUp had no support to install Plugins and Extensions. This meant LightUp had to have its own installer to copy files to the correct locations.
Starting with SketchUp 2015, there is now a built-in Extensions Installer that offers a simple method to install plugins via .rbz files. It lives in Preferences->Extensions->Install Extension
We have started to transition over to using the SketchUp Extensions Installer system for LightUp. Initially it will be for the free 30-day DEMO on WIndows. Website www.light-up.co.uk

New tutorial for LightUp 4.4 http://www.light-up.co.uk/index.php?t=tips
Just released the Android player for SketchUp models lit with LightUp.
You can navigate your lit models in realtime, use any Scenes you've set up and take measurements from your model.

THANK YOU!
I've updated the German text with what is suggested.
As you will have seen, we have been updating the website. How is it best to express in German the new English text?
Adam
May be better to simply have a single rectangle of glass material behind this material.
The LightUp website has been spruced up for Spring, check it out: https://light-up.co.uk/index.php
Also updated iPad LightUp Player available with improved performance and fixes.
Get it here: https://light-up.co.uk/index.php?t=player
New Android LightUp Player is nearing completion and looking great.
Last but not least, a new version of LightUp for SketchUp released (v4.2e) that has improved realtime Section Planes for Poche effects, and continuous 2-point Perspective mode which is very handy when doing flybys.
Adam
FREE to develop, yes. But Its 5% royalties on shipping applications.
LightUp builds atlases internally, so you could export using LightUp using Autodesk Filmbox format (FBX) and choose 'Single Layer' and 'Dynamic Resolution' to get what you want - and you could export the Ambient Occlusion at the same time. 
LightUp also has an Editor script for Unity that makes dual layer imports very simple.

Also be aware that many raytracing tutorials use 'time-lapse / fast-forward' to avoid long delays in the video - are you sure it was really 3 seconds of elapsed time?

I've made a simple model to help understanding.
Open it and you'll see a single face, but its actually rhomboid with the "sides" facing toward the camera direction.
You can't do a worldspace test to determine visibility in a non-orthonal projected space.
EDIT: well thats not entirely true, but you need more than camera.direction.
Pretty, but whats the use case?
@tig said:
In code you can also paint the same material on every face's back as it is front.
So for example iterating all faces to make sure any ones using a transparent material, then have the same material on both sides...
faces.each{|face| face.back_material=face.material if face.material && face.material.alpha < 1.0 **&& !face.back_material** }
The part at the end -&& !face.back_material- only paints the back of a face if it is in already in the default material, BUT omitting it forces every face which has a transparent material to have that material on its front AND its back sides.
And of course this ignores Group materials that override any face with the Default material. So you can't just check when face#[back_]material is nil 
@tig said:
In code you can ensure a face's normal is towards the camera [get angles between the view direction and the face.normal], if >180 you are looking at the front !
TIG, strictly this is only true for a parallel projection. Its broadly correct for perspective projection, but not for all cases.
Based on some great feedback, we've released LightUp iPad Player v4.1. Its just been accepted by Apple AppStore.
Its got lots of user-experience polish and also a new screen to manage your downloaded .luca files.
Hope you like it.
Adam
Saw a 3dsmax render of a proposed bar and I thought I'd have a go recreating it with SketchUp.
SketchUp 2014 + LightUp v4
10 min lighting, realtime render
I'll try and post the luca file so you can fly around it.

120 seconds x 30 frames per second = 3600 images with a duration of .033 each (1 second divided by 30)
Correct
@pmolson said:
Lets say I have 20 scenes and the animation settings are set to 30fps
My scene transition settings are set at 2 seconds (just because that is what it was set at)I know from past experience that this set up generates 1142 images.
20 x 2 = 40 seconds animation @ 30 fps = 1200 images
@pmolson said:
f I want a video that plays at 30 fps and I want that video to be 2 minutes long...
120 seconds x 30 frames per second = 3600 images with a duration of .033 each (1 second divided by 30)
OK, better to say 120 seconds / 20 scenes = 6 seconds per scene transition.
So set the transition time to 6.0 seconds and for 20 scenes it will be 120 seconds long. Job done.
@pmolson said:
does changing the scene transition time change the image output per scene?
Yes because video is output at 30 frames per second. More seconds, means more frames.
