Re: Toggle visibility INSIDE grouped items

I don't think I have fully grasped all the subtleties of the comment hierarchy here yet. My intention was to comment upon mazoolas reply to me, but for some reason I can't get my comments to be addressed to the right person.

Well...

Re: Toggle visibility INSIDE grouped items

@Ceciliabr

I have so far never seen any trace of an object after applying this texture to it.


Nor have I seen a 'visible invisible' texture after applying a fully transparent PNG as a material -- but some folks have. My guess is, as OK said, it has to do with SunFlow's handling of surfaces -- which, my recent experiments suggest,* is a surprisingly complicated topic.

My suspicion, though, is that it has less to do with calculation of surface normals than with glossiness; that is, I suspect a glossy invisible surface, besides being an oxymoron, would be more likely to display artifacts than a matte invisible surface. Applying an invisible texture to an entire object might also lead to different results than applying the same texture to individual components of the object.

All this is pure speculation, though, as I've not tested my hypotheses -- something I'll no doubt do the next time I have something far more important to put off doing. wink

* I should note in passing it was your recent post that sent me down that particular rabbit hole. While for most of my life I made my living as a technologist of some stripe -- and even once contributed about half the pages to a book on programming in Pascal, available in English and German wherever painfully obsolete computer texts are found -- I'm actually an English baccalaureate whose last math or science class was in high school; I'm definitely, as the idiom has it, 'punching above my weight.'

Of course... writing the address. Why didn't I think of that?

And the "quick reply"- button must be for people with great haste – but you still have to write the address – right?

I think I've got it now... :)
