[Plugin] ShadowProjector
-
I'm working on a fix...
-
Here's v2.0 http://sketchucation.com/pluginstore?pln=TIG_shadowProjector
It is completely rewritten to be faster ad more robust... -
Here's v3.0 http://sketchucation.com/pluginstore?pln=TIG_shadowProjector Along with ignoring Hidden faces/objects and those assigned OFF Layers, it now respects transparent faces [<70% opacity] which won't cast shadows, and similarly faces with the default-material faces within a container that itself has a transparent material and which doesn't then cast a shadow etc.
Objects with cast/receive shadows 'unchecked' settings are now fully respected in the shadow analysis.
Faces which shade themselves [because they face away from the sun] are automatically assigned 100% shading with no further analysis...
A glitch with report writing if type was 'lines' is now resolved. -
Latest version installed. Get this in console when trying to run the tool.

Obviously it shouldn't do that
Did you have a face preselected ?
I'm on to it...
-
I did have a single face, correctly oriented selected. I tried it first on a chair model I was working on at the time when I got that message. I quit SU and restarted. Then tried it with a simple box in a component and an ungrouped face. Same result.
-
Here's v3.1 http://sketchucation.com/pluginstore?pln=TIG_shadowProjector
It fixes a glitch caused by a simple typo.
The test for 'receive-shadows' for a container being unchecked was inadvertently being run even if the selected face were in the model entities, which of course cannot have that set !
Now resolved.
Thanks Dave for feedback... -
Glad to help, sir. I'll give it a try when I get home from work and let you know.

I tried it on a simple box and face. It worked fine. Tried it on a slightly more complicated model and it splatted, twice. I can send you the SKP if you wish.

Please PM me the SKP[s] that splatted.
I have taken pains to minimize this kind of thing, so I'll be interested to see what's up.
I know that very tiny edges can cause issues as they won't intersect with the face to form an 'edge' - but from your modeling I'd expect no such issues
-
I'll send you the SKP when I get home from work. Sorry for the delay.
-
Here's v4.0 http://sketchucation.com/pluginstore?pln=TIG_shadowProjector I have completely recoded it.
It works with Dave's example SKP [PM'd] and all others that have had issues in the past.
It has so far worked faultlessly.
It is now faster and more robust too...Feedback please...
-
It works!
Excellent work, sir. Thank you very much.

Inspecting mirrors is a thing I could easily see myself doing.

Still getting fairly consistent crashes on a large and moderately complex (29,500 faces on an area of interest of about 55 acres) model. It seems to get through a few steps, though, as it never crashes until a few minutes in. Is there a log file somewhere that might show what is causing the splat, or at least what stage it's happening at?
-
I suspect this is just too complex, sorry.
Have you tried splitting it into smaller parts...
-
I did at one point, and one relatively small section (2-3 buildings, maybe 1/2 acre) still crashed it every time. Will try to reproduce that and post the file to see if there's something squirrelly going on with the geometry in it.
-
Since 'shadow-projection' is usually relating to 'massing' studies, have you considered making some simple massing blocks [grouped] on their own layer[s], then switch off those layers belonging to the complex parts of the model you no longer need, and then retry shadow-projection ?
Use scene-tabs to help with this...You must appreciate that if there are many thousands of edges and faces, then there are millions of calculations need to get the potential shadows on each face, these go up exponentially as the amount of geometry increases...
This tool is based on Ruby which is inherently slow.
Faster based C tools would be faster, but you must also notice that SketchUp itself becomes sluggish when you have shadows on and try and navigate around such a ginormous project ? -

Can we get this result? A sketchy line hatch parallel to the rays?

You'd need to apply suitably textured material.
You could edit the shadow-projector's material to have a texture.
Or apply a new material onto the grouped shadow-faces.
You'll also need to rotate its texture's pattern to suit the sun's direction...
If you have a number of regularly used sun-directions - say 2x 45° angles then make 2 materials and use those ?
Here's a quick 'botch-up' material...
