Shape Bender - preview

Chris,

This is an amazing piece of plugin and I can figure out the kind of complexity of such work. Hat off! and very impressed by your talent.
So I use the dedicated smiley

Hi Chris

Bending shape with guides: surely an important improvement. I like the way we can
reverse the direction. It will simplify complex following shapes too (railways, roads,stairs..)

Cheers

If I good understand I can use your future plug for slice a box if my line is a simple straight line?

Or your fist box is yet sliced?

The script slices the model as necessary. In fact, it really mangles the original geometry at this point. So you'd better have a back-up copy of whatever shape your bending

Ps it is not a little war with the last Fredo6 Bend?

Oh goodness I hope not. My script only focuses on bending a shape from one shape to match another shape. Its really quite different than Fredo's bend tool in the incredible freescale 2.0 toolset.
I've been thinking of it as shape bending while I've been working on it, but maybe it more like shape morphing? Though morphing sounds like I'd be promising an awful lot, and I'm not

This looks very cool Chris and will be an awesome addition to my toolset

Although it could all be one-step undo-able if the code were done within a start_op'/commit_op' pairing anyway - to avoid that potential mess/loss why not have it group the shape and copy it if desired***, you'd do your slicing and bending etc and finish with the copy kept if specified first. Its probably best to group the shape anyway and leave it grouped [and its copy if specified] to avoid geometry clashes between the stuff and the rest of the model ?
***You could have 'Alt'+'select' shape [or something like it] to keep a copy or raw 'select' shape NOT to keep a copy...

Wow..this looks like one very interesting plugin.

Second that.

Brilliant!

Amazing!!!

About the last example of the video: Do you think that will work if the endline is directly into the surface? (for example using Fredo´s Line On Surface).

Or for making it easier to bend on surface, do you think that can work like the SU drape tool where you select the group and then the mesh on which you want to bend? (Of course that instead of edges it will bend the group)

geez chris, this looks great.

i sure hope you can work the bugs out of it

i'm curious if you're testing it with (or even concerned with) sharp bends as well?

[edit] well, i know arcs are basically a bunch of sharp bends so it shouldn't be a problem.. just wondering if the shape needs to be bent to an actual arc (as in - if you check the entity info, SU will know it as an arc)

solo

Great looking new attraction mate!

I hope you do not mind me making a request that i believe is relevant, I've always wanted a sweep function, like the .gif below, is this at all possible?

Very cool. here's the ICON png. (Copywright issues notwithstanding of course)

craigbic

Totally awesome! I can't wait to get my hands on this! Bending along a path with reversible start and end points is a true advancement for SU. On a side note, excellent video.

LMAO! I am such a huge Futurama fan so that icon is just PERFECT on so many levels!

Moving... too... fast...

Too... many... improvements... can't... keep... up...

Great stuff. Add my vote for the Futurama Bender Icon

WOW go to bed and wake up to a whole bunch of comments, excellent! Thanks for the support, compliments, suggestions, requests and mascots. There are 3 major bugs that I think will fix a lot of crashes.
Problems:

When the geometry is longer than the provided line
The bending is not quite accurate. I've got a small error in the calculation somewhere because it actually skews it just a bit. It just wasn't noticeable in the video.
Write in a snippet to deal with the first and last segments of the curve.

I think those 3 improvemnts will be enough to get this script ready to put it out to be played with.

Anyhow, enough with the boring details. Thanks for watching the video. I will consider and discuss all suggestions.

@Solo, I like the sweep idea. That would require me learning how regular sweeps work. And while it is similar to this script, I think it is a script of its own. Though it seems like it shouldn't be impossible to write. Its on my list of scripts I wish I had written (along with quite a few others).

@TIG, the script is actually already set to work with groups. I think the only reason I explode it was to get the vertices quickly, but I have since found .flatten! and .uniq! so I can get a clean array of vertices very quickly. So my script works with groups as long as they are not rotated - which I want to fix. I want it to work with a group/component no matter the orientation. I have not sat and thought that through yet, but I'm sure it will take some thinking to do the slicing through a component which has been rotated. It requires transforming all the calaculations, which my brain gets tired just thinking about. So ideally, at some point, the script will accept a group/component with any transformation (including scale too, I forgot about that).

All right, again, thanks for the support!

OH yeah, @Daniel, yes, it should work just fine on a line drawn on a face like in your example. I'm pretty sure that will work. The line and curve selection and reversal portion of the script is pretty stable. I put a lot of time on that while I was sitting around, completely unable to figure out the bending function

wolfy

Wow Chris, very exciting! It's awesome to see this kind of talent! Can't wait for it's release!

If you explode a group and then regroup its entities immediately then that new group's orientation is square to the world axes. If it's an instance then explode and group it's entities, ditto ?

Alternatively an instance's transformation could be applied to your cutting plane(s) (face?)...

A transformation includes the scaling ? Exploding it freezes the geometry entities with the previous scaling as if they were drawn in the world originally ??

I never tried it because I presumed that it would run into errors if the group was inadvertently touching other objects. I didn't SU to do any auto breaking and joining of edges and faces, thereby messing up my selection set. If the group is laid directly on top of the line it is aligned to, if I explode the group, will that line interfere? I'll play with it and see what kind of results I can expect.

@tig said:

Aha! I bet I could figure that out. My intent was to make it so it could occur on any axis, with any group/component. I think that I could transform the plane to be perpendicular the original line's orientation, then line it up and transform it to meet the groups transformation....Sounds do-able.

@tig said:

I think this is where I'll begin, is by trying to explode and re-group to force the component to align to the world axis. It would save me some headaches at this stage, but it would be an improvement over the current condition where the user has to do it manually.

Great ideas TIG, you've been a huge help to me with these scripts,

Chris
