Method or plugin for subdividing like this sample
-
I tried the new code and it's better but for other non perpendicular faces it still gives some weird results.
A cylinder for example.
I have attached another example of that below. Hopefully it's possible to get it right for these cases also. -
-
But the code was so useful I couldn't help myself wanting it to work on more types of objects...
...what if I say: please?
-
I see a lot of possibilities here.
Fake beveling at render time?
Please Sam?

Sorry guys but I see no possibilities. In fact it is impossible. Why, because the 'offsets' only work if all the angles at a 'corner' are the same. Plus, what do you with 'concave' angled corners?
-
In Thomthom's EdgeTools there is a script for manually diving faces called "Divide Face".
It have some clever ways of getting the "splitting edge" to match the face's surrounding edges.
Maybe if you took a look at how he does it there it might be possible to implement into your code? -
Guys,
This is what Roundcorner does in the first place. So doable, but the code is not exactly concise and straightforward to catch all topological situations, especially those where the offset line don't meet at corner edges, as highlighted by sdmitch (just take an elongated pyramide for instance). Not mentioning concave corners and other complex geometry...

@fredo:
So, when will your new version with all quad face corners be ready?
I believe you posted a sneak peak some time ago. -
That's a pity, but thanks fo the explanation. When rendering an architectural subject bevels make a lot of difference in image results and realism. However when working they are too cumbersome and when sending to Layout or CAD to document the building and dimension it, they become even moreof a nuisance.
Having some kind of temporary bevelling that you could toggle, loke subd, would solve the issue.
I guess a lot of us would find that an incredible tool and I thought, for a moment, it would be possible...
Even so,thanks for your time gentlemen!

Hi guys
This is what I came up with a few months ago, but it fails when curves or inner loops exist.
Also it uses the offset.rb from Smustard(TM).
By using this combination of soft and smooth you are able to put correct dimensions in both SKP and LO
If you need to get rid of the changes the plugin Fix101 takes care of it.Any ideas to improve this?
#CSR create soften edges for renders
ss = Sketchup.active_model.selection
Sketchup.active_model.start_operation("test")
old_edges = []
new_faces = []
ss.each{|e|old_edges.push e if e.class == Sketchup::Edge}
ss.each{|s|new_faces.push s.offset(-0.0625) if s.class == Sketchup::Face}
old_edges.each{|oe| oe.smooth = true}
new_faces.each{|nf| nf.edges.each{|nfe| nfe.soft = true; nfe.hidden = true}}
Sketchup.active_model.commit_operation
-
After adding offset.rb it worked.
However the old edges are hard and the new ones are soft. -
Can anyone convert it to a plugin?
-
I'm trying...
I think it would work better if it only operated on edges that are hard.
How would one do that? -
And do you think it could have a method for operating at render time or is it too slow for that?
Like tag some objects and apply the effect when hitting Thea's render button and then undo it (using skatter's method)?
-
I don't know yet.
It has some bugs as it's not working correctly on for example a cylinder with soft edges. And some other things that would need solving first. -
I do this sort of thing manually on a daily basis and it is frustrating that a number of plugins come very close to automating much of the process.
A quad version of Round Corner with a subdivision mode (just adding the required loops) would be awesome.
Having more control over the addition of loops in Quad Face Tools would be very helpful. I seem to recall that this is planned for the next version.
For subdivision at render, I think that could be possible with SubD at some point in the future. I imagine that getting it to play nice with all the different render engines will be quite a big ask.

I remember Thomthom was talking with both Thomas (Jiminy) and Tomasz to make it happen. Maybe it's being developed as we speak, maybe it stalled.
Anyway what I wanted was simply to have raw geometry without bevels, so I could design easily with sketchup and some method to fake bevels so I could render realistically, but I don't want to have permanent bevels.
In the end I always sacrifice bevels so I can keep desiging but the results are always too CG... that's the best option I have for my workflow...

Yes, some Skatter wisdom would probably help to move things in that direction.

The way I envisioned that working would involve a new version of Round Corner that adds the loops needed for SubD bevelling and then assigning a SubD @ Render condition to the geometry.
Whilst it wouldn't reduce the geometry/calculations rendered, it would keep models manageable and be partly non-destructive.
Naturally the ideal would be completely non-destructive bevels, but that's not going to happen without major changes to SUp's core engine.
Personally I leave all bevelling until the last minute, when I know there won't be any design changes. Sometimes I'll save non-bevelled versions of components in my project file - just in case.
-
Don't know if it's possible but if so, running a script right before and after render could perhaps create a fairly non destructive workflow.

LOL... What about last minute changes?
The thing with rendering, in my case, is that I do it to test design and let it cook longer to show it off to my clients.
Bevels make a lot of difference but sincerelly, my clients don't give a damn about that added realism. However I've seen the work of render gurus like yourselves and get frustrated with my results.
So I want bevels, but I don't need them, but I want them, but I don't need them... I guess turning them on and off would be the ideal solution.
