[PLUGIN] Voronoi + Conic Curve

MattC

I've unpacked it just as at was, so icons sits in a folder Plugins/voronoi_conic.
Somehow code

cmd.small_icon = "voronoi_conic/icon0s.png"

, does not work for me (Win 7 and WinXP)
Strangely:

:

cmd.small_icon = "icon0s.png"

and 2)

cmd.small_icon = "./icon0s.png"

both works.
code 1) I understand as icons and ruby that invokes toolbar are in the sam location.
But 2) searches for icons in Plugin folder...or am I mistaken?
Does it work for You straight away ThomThom??

Haven't had time to try it - been very busy. Just monitoring the forum a little...

Hi the pjt !

Great work!

Few comments :
1/ Could it be possible to undo the voronoi generation in one go ?(ctrl Z is going back through all the steps of the generation)
2/ It does not generate the voronoi all the time. Sometimes nothing happens. Any idea ?

Thanks for making my day with those plugins!

Matt's original ruby files (could be found in the first post of this topic ) displays a dialog box that counts each step and you should verify each step by pressing OK button .. It could be good for preventing unwanted results ... ( but it was annoying for me )

also you can delete each group of resoults and doing the Voronoi command on a particular face ...

but above all I'm not a programmer Author ... I just wanted to help Matt by doing some routine steps of making an SU Extension ...

if You can post Your .skp file then I can take a look at it.

Great Plugin Matt,

However, some regions will not work for some strange reason. Snag in program somewhere.
Good start though. I wish the ruby God's will help complete this one. Its very useful for creating metal sheets with these patterns and much much more. I used the "conic curve on face" and pointed to each face.

Thanks!

sorry for the late reply, it´s a new file, no other geometry in it. if i open the ruby console i get this:

i hope you know what it is matt i would love to do something cool with your plugin.

if i don´t open it i get this:

If I may add one wish : The tab options for the conics should remember the last options chosen.

Here it is.
By the way I'm using pjt's plugin. Thanks for looking at this!

Hi Matt ... please post the toolbar (my work )to the first post ... copyrhight ? !! feel free .. it's our plugin .. not my" plugin . and I also posted PSD icons for you ..
ICON folder path ? .. I'm surry for this bug .... but I myself tested it on my 2 computers with windows 7 and 8 (SU8) .. and It was fine for me .. ... but if there is a problem please repair it and use my works in future versions ...
good luck

MattC

Hi,
I will do it as soon as I correct bug that nectares reported.
Also I already adressed some things from a wishlist.
So stay tune.
Also , evereyone that is using pjt's wrapped wersion with toolbar, please report if You can see icons, I don't know if it is only me that have this problem ??
I don't want to fix things that are ok.

In general Stat tuned. Version 1.1 is coming.

Same thing for me.

Also Tab key does not open dialog box (Macbook pro), for me.

TIG

On a MAC the TAB a onKeyDown method doesn't work [known bug!] - you need to use a onKeyUp method to spot the press of the TAB-key for MAC AND PC.
Also note that TAB key-mapping will differ between PC and MAC - if key==9 || key==15... DON'T use key 48 as that is only TAB on some Linux setups [I think] and causes issues with mainstream users [== 0 ?] - an error is some of my older code that should be fixed in MY scripts

The regional differences might be caused because there's a ',' as a decimal separator rather than a '.' ?
If dialog values are taken as 'float' or 'length' then this should be accounted for automatically by Sketchup ?

Use inputbox rather than UI.inputbox as it checks user inputs better...
[include a require 'sketchup.rb' in the first line of the script to ensure it's available to you]
Don't use @@dek.to_mm you've already predefined it as a 'length' as @@dek=25.mm - later you mess with it again .to_f.mm - because you first set it as a length then the user's current units will be used instead anyway - there's no need to restrict it to 'mm' at all - just use 'Offset:' as the prompt... similarly the other inputbox values can only be what you set them as so if it starts as a float the user's input must be a valid float so typing 3 returns 3.0 anyway...

Hi MattC

Still unable to use your plugin. Here's the error message and file...

Error file

Error message

TIG

It's possible to have two 'lines' that don't intersect and produce 'nil' as the result, so the code needs to trap for the existence of the point and only proceed with it if it's not nil...
That should be a relatively simple 'trap' to construct...

MattC

True TIG
I already implemented this trap, but also encountered another case that is a bit problematic.
It is geometry limitation of Sketchup.

I will update script when this will be solved, in a meantime if anyone also has non-working combination of points, post it here.
I will have more material to analyse.

Matt

TIG

Putting the code inside a begin...do_point...rescue...end structure will allow the code to fail on the point without a crash ?
But a simple intersect_lines...if point...do_stuff...else...next_point...end would suffice here...
Something like:
if **int &&** (test[0]==0)&&(test[1]==0)&&(test[2]==0) intprim=int+int.vector_to(pointstable[bpntindx])+int.vector_to(pointstable[bpntindx]) points<<intprim.project_to_line([midlines[0][0],midlines[0][1]]) points<<intprim points<<intprim.project_to_line([midlines[1][0],midlines[1][1]]) els**if int** points<<int end
and
if **int &&** point_is_between(p1,p2,int)&&point_is_between(polygon[i],polygon[j],int) point<<int end
AND any other place where int is set as an 'intersection' that might fail - test for its existence before trying to use it.
Only uses int if it's not ' nil'.

MattC

Yup, second way is exactly how I changed it.
My fault was testing it on set of random points, and combination of 3 colinear points didn't occure.

Hi there,

I found this Voronoi so cool... couldn't resist posting this.
Interacting with the mouse moving over the points.

Is that code any useful to ruby Heros ?

Hi Matt
Great plugin mate... lots of potential here
But I have a little problem: you say that for this to run properly this plugin requires "delauney3.rb"
I don't have it... I only have "delaunay2.rb".
I get the Typical plugin error..."Error loading file VoronoiXY.rb no such file to load -- delauney3.rb"

But I can't find the robust version that TIG is refering to here: http://forums.sketchucation.com/viewtopic.php?t=8314

I did got the "conic curve" plugin to work and it's awesome.

Also tried to use "qhull.rb" but it's a mess! I just get flashing DOS-screen ans crashes.... It's a shame, since it would also be a super-tool...
Have you heard of any progress on that???

I'd really appreciate your help so i can start using this baby!
Thanks!

My 'modularized' version of 'delauney' [ delauney3.rb] ships as part of my 'Triangulate Points' tool - which is very much like Didier's original... BUT avoids potential clashes with common loose method names like 'triangulate' !
http://forums.sketchucation.com/viewtopic.php?p=301274#p301274
It doesn't replace the original, it just makes a 'safer' alternative for any tool that is using it instead...
