[Plugin][WIP][OpenSource] Bezier Surface

thomthom

Do you use Knotvectors for the patches ? Or are they interval-based type powerbasis functions ?
Edit: Ah right, they are not spline-based, (duh). So you go through the C-extensioncode right ?

It's simple bezier quad patches with 4x4 control points each. The bezier calculation is based on the bezier example script posted by @last many years ago, I just ported it to C for faster calculations. You can see the source in TT_Lib2.

How do you add Tripatch to Qaudpatch ? Possible ?

No, this was on my todo, once the quad patches was done. I removed the main toolbar button for it right before release, but forgot there was menu items and that second webdialog toolbar. I should push a new update the removes the unused controls in the dialog.

This rough test torso is less than five minutes work.

Really? I didn't expect the extension to be that useful in it's current state. I hope people do post back more picture.

Thanks you very much for the plugin!!
I installed it in SU2014 & SU2015 on Mac but the plugin didn't work, I found a conflict with smartdrop.rb and Sketchyphysics, I deleted smartdrop.rb (I use tt.raytracer now to drop components) and I have deactivated Sketchyphysics on SU2014 with Sketchucation Plugins Manager and Bezier Surface work fine now.

it looks super nice thank you but it doesn't work for me (sketchup 8 on win7)..
i suppose i installed it properly and also updated ttlib to last version..
i suspect it may depends on some conflict with tons of other plugins..

Should work with SU7 and up, I think. Any error messages?

Same here. I only had it working in 2014.

Error "defined method `force_encoding' for #String:0xb10993c"

This is "probably" and Ruby 1.8 error. I have the impression that many authors will stop supporting SU 8 soon.

Yea, with my new subdivison extension I'm certainly dropping support for anything older than SU2014.

Though this was written before SU2014 and it should work. (Though might have introduced a bug when I added SU2014 support. Can you provide the full error message and exact SketchUp version and OS?)

@panixia said:

yeah. force encoding blablabla.. getting similar message when loading sketchup

The bla bla bla bit of error message is in fact very useful for developers when debugging errors - please post all of it when reporting issues.

@jolran said:

It may have be a condition set on line 26 in the loader rb
"file = FILE.dup.force_encoding("UTF-8")"

Ah - right, I'll fix that and push an update next week.

It's just always updating...

Cannot Click or DoubleClick

and when SU opening， nothing prompt

Any errors in the Ruby Console?
What SketchUp version?

SketchyPhysics is known to clash with extensions. I think an update is coming.
Not sure about smartdrop.rb - not familiar with that one.

A quick test taking like reference the torso of Box.

i'm pretty much sure that the "blablabla" part of the message returned ad least 3 different values with different tries (that's pretty odd i suppose) the last try being: "Loading File tt_bezier_surface.rb
undefined method `force_encoding' for #String:0xec947b8no such file to load --"
hope this can help

I'll mainly focus on my subdivision extension over this one. Though I'll try to maintain small bug fixes and pull requests. I'll see after SUbD is done what I do with this project.

Btw, I have a fix for the compatibility bug with SU2013 and older. I'll be pushing an update.

I understand.

When there is incompatibility (Sketchyphysics 3, SKalp, (my case) etc...
Who is faulty ? These plugins or Bezier Surface ?

@oxer : Rodin 2

thomthom

Bezier Surface is confined to its own namespace - so the only thing I can think of would be possibly other extension clashing with observers. SketchyPhysics has been known to clash with many extensions - though I'm not sure if it's been updated recently to address that.
Odd if Skalp clashes... maybe observer fights?
Do you get any errors in the Ruby Console?

See my previous posts from here

Messages were the same that the restant on my post linked

So for have no message errors I disconnect plugins after plugins.

ok, in my case progressbar.rb is the culprit

now it's smartdrop

it changes..

Now I Know what happened
Smartdrop clash with TTlib2
something named "definition"

so I change "definition" to "a4sddefinition" @ smartdrop.rb
and it works

Smartdrop.rb

.

here's a simple introductory example.. maybe something a lot of people can use..
seamless background for rendering

1- draw the patch next to a flat plane:

2- double click the patch to enter the editing mode.. select the back line:

3- using the blue arrow on the gizmo, move the edge vertical:

4- using the red arc, rotate the edge downwards 90º (degrees will be shown in the measurement box)

5- using the blue square, scale downwards.. align the green control point with the green axis

6- change the segmentation in the measurements box (i think i used 20)
