[Plugin] Geom Interpolated Curve ver. 1.3.

[kirill2008]

crvsmth.rb

Description:
Plug-in, which smoothes selected curve (a kind of substitute for spline, but “crvsmth.rb” does not use any kind of polynomial functions)

How to use:
Non Interactive Way
1) put “crvsmth.rb” to “Google SketchUp 6\Plugins” folder
2) start SketchUp 6
3) draw curve or make curve from a set of edges using Rick Wilson's 'weld.rb' plugin
4) select curve, right-click on it, then choose “Geom Interpolation...” command from the context menu
Interactive Way
1) choose "Draw Geom Interpolated Curve..." command from "Plugins" item of the main menu
2) draw curve interactively (it begins to appear after the 3-rd point placing)
3) hit <Enter> key or left double-click to accept drawn curve, <Esc> key discards made changes

ver. 1.1. demo videos:


ver 1.2.
New features:
- interactive drawing of the curve is added
- control points recall across sessions is implemented

ver. 1.2. demo video:


ver 1.3.
New features:
- explanation geometry drawing mode is added into interactive control points editing tool (<right-arrow> enables explanation geometry, <left-arrow> disables)
- incremental changing of 'Iterations Count' value is added (<up-arrow> increments, <down-arrow> decrements)

Very cool, particularly like the explanation lines

[Pilou]

Funny for curious caligraphy

[Jörg]

very cool, kirill!!!!

Thank you very much!

[notareal]

I like it.

[Fletch]

good idea...

I'm concerned that the word "Smooth" is already "taken" in SketchUp... and usually applies to a specific type of edge, so if we could come up with a better name for this tool, it may avoid confusion.

may I suggest "Curve Toy" or "Curve Control" or "Squishy Curve" or "Marilyn Monroe" I don't know... something unique.

Very cool. What do you do with the explanation lines? can you manipulate the geometry with those lines? Sorry I am not with SU range.

Very interesting videos. I will have to review them again.

I agree. I like "Marilyn Monroe"
Well maybe "Geom Interpolation" (long, but close to what it really is).

What do you do with the explanation lines? can you manipulate the geometry with those lines?

Unfortunately explanation lines are only to show, how intermediate vertices were modelled (lines are practically useless and there is no way to interact with them only to admire).
Actually it is necessary to implement 2 additional 'control lines' at the start and at the end of the initial opened curve to affect 1-st and last segment curvature (the same way as cubic spline). Closed curve does not need it.

And another issue: current version does not 'remember' control points across sessions also (the same as 'ctrlpnts.rb'). I'm on my way to implement such functionality.

Thanks a lot !! Very usefull for me.

Very usefull for me to !

Thanks,

[kwistenbiebel]

Tremendously useful for me
It seems like a good plugin to make the curves as a start for a soap-skin-bubble session.
Thanks Kirill!

This is amazing and very very helpful, thank you very much for your generosity.

In the current version (1.2.) the command name to launch the plugin was renamed to "Geom Interpolation..." to avoid confusions with other commands.
And now script recalls control points after opening the file which contains curve. I'm going also to add interactive control points editing (the same way as in ctrlpnts.rb).

Kirill, thank you for this plugin.

Several I watched your videos demonstrating it and then tried to use it. I must be missing something because you seem to be able to make it do things I can't. Could you give a little basic training?

I can get the curve alright after setting the control points out. After that, I select Edit Geom Interpolated Curve... If I click on the left arrow key I get some additional points but no lines joining them to the points on the curve. Also, if I click on a control point and try to drag it, nothing happens. If I click on a control point and let go of the button, the next click creates a new point away from the first point as if placing a guide point with the Tape Measure tool. Nothing I do will let me edit the curve.

I've tried following the messages displayed at the bottom of the screen but with no luck. Could you give some guidance? Thank you.
