[Plugin] ShadowProjector

Hi TIG
How many smart tools from you I haven't tested? a bunch of them I guess: it's a pity (but they are carefully bookmarked
).This one one more time, is full of potential

Perhaps it's my Christmas Present to SCF...
I've been working on it for some time... and I finally got a moment to polish if up for its release... -
Hi, TIG:
Another great tool from you. -
-
Cool idea, TIG!
-
fantastic!!!! a great help for architectural drawings instead of cheap renderings
thank you

Neat TIG!! DO you ever get time to work for money???
This is a little like GOH's 1001Shadows, right?
http://www.1001shadows.com/en/index.html
Not the same thing, this shows shadows cast on selected faces by objects, I don't have that tool but I think 1001shadows projects all onto the 'ground' [of course if you have a ground-plane face selected my tool does the same]. My tool also has options of displaying the shadows - from a line, to a face, to a face with statistics...
That's pretty cool, TIG.

Something cool about this but not sure how someone makes use of it. Is it only so you can export a polygon and use it in a CAD rendering (2d)?

It's as useful as you think up uses for it...
For example, checking the % of solar shading on some selected glazing at a certain Date/Time.
Getting the area [sq'/sqm] of perhaps some selected glazing or a solar-panel that's receiving [or not receiving] direct sunlight...
Because faces using a translucent material don't show normal shadows you can now use this tool to add a visible translucent 'gray' shadow-group face [with no edges] onto selected window-glass etc, to fake these shadows in a Sup render...
DAE files etc don't contain shadow info but you can now include a faced snapshot of the shadows if desired.
I only invented the tool - you lot need to come up with uses for it... -

That was exactly what I wanted to experiment: colored glasses and their colored shadows...
Glasses and bottle are drawn , but
I can't make to "ShadowProjector" draw their shadows.. Probably too complex shapes.

Simon,
what scale are you trying at, is it a small triangle issue... just a thought

Hi John
You are right in the way I never take enough care of the scale !!!
In this occurrence, the scale is not too small but too big: a glass of 135cm width !! You may be thirsty

Is the orange face 'reversed' - view in Monochrome mode to see.
Shadows are only cast onto front faces.
Also there is an issue with tiny faces/holes and groups/instances placed exactly onto a face and casting a shadow.
I'm doing a fix now... -
Here's v1.1 http://forums.sketchucation.com/viewtopic.php?p=371243#p371243
1.1 20111214 Addressed issues with tiny faces/holes and group/instance sitting on face whilst casting a shadow. -
Hi TIG
This tool is a great idea ++
I'm very sorry The updated rb doesn't work at all and anymore for me (and the first version is overwrited arghhh!).Please can you pick an eye on my following SketchUp 7 model ?
Sorry for trouble

I can get it to work with reduced complexity [removing the 'glass']...
[attachment=0:12he1z9c]<!-- ia0 -->Capture.PNG<!-- ia0 -->[/attachment:12he1z9c]
I don't have v1.0 either [lost it!]
I'll investigate...

Me too
I'm going to test the ShadowProjector with incremental complexity models...
thank you for your patience and kindness

Hiding the glass, or putting it onto an 'off' layer work too...

As I can conclude , ShadowProjector not only take in account the geometry casted by the shadowed selected face, but also the entire geometry of the model.

Alas ShadowProjector is stopped by the first model

Simon.
PS1: I am not happy to be the one who show the tool limitations

You are right.
It would be better/quicker if it found only the objects potentially casting shadows on the face...
BUT the algorithm to do that robustly is beyond me [at the moment].
So at the moment it checks everything that's active for shadow casting even when it doesn't even cast a shadow on the face.
So I suggest that keep the 'active entities' simple [using temporary grouping?] and do small sets of shadows...
