      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.

        I take the slow, deliberate approach in my aimless wandering.

              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. 👍

                purpose/expression/purpose/....

                  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...

                                        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.😒

                                          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...

                                            It now limits its purview to potential shadow-casting objects and is therefore quicker... 😲
