[Plugin] Sketchup Ivy

thomthom

@thomthom: I guess its expected behaviour, but if you try to classify a point on a face which is inside a group, the point is classified as not on the face. The result is this.The second problem is that some branches in the plugin sometimes manage to "break through" faces. Im not sure if this is a classify_point issue. or plugin algorithm which sometimes break, but cant solve the problem 100%.

Have you taken into account the transformation of the group? If you pick a point on a face inside a group you get a point for the current context, and then you need to apply the transformation for the group(s) which the face is within.

@sadyo: The tool code is rewritten (after shameless spying on thomthoms Selection_toys code. Hopefully i handle mouse events right this time )

For handling Shift, Ctrl etc?
I think you might want check a more recent plugin, like Select Curve: http://forums.sketchucation.com/viewtopic.php?t=31091

I'm not sure if Selection Toys does it 100% correct. I can have a look in the code and compare against Vertex Tools (which I have tested on Windows and OSX).

No I haven't. If i make a single face and grows an ivy on it, without grouping the face first, there's no problem at all. But if i group the face before growing an ivy on it, adhesion doesn't work, a consequence of classify_point not returning 1. Unless a transformation is applied to a group by the very act of grouping, transformations itself cant explain this behaviour.

Can it be that Sketchup interprets this situation as if the point not being on the face itself, but "on" the group?

I couldn't find classify_point anywhere in the code... not in the current version?

How do you obtain the point you test against classify_point, an InputPoint?

Look in livevector_core.rb. line 187.

classify_point is used to find the closest face to a new node on a branch, so the points tested against classify_point is the last point on each branch.

thomthom

When you test your point against a face nested inside groups/faces you must trasnform that point to the co-ordinates of the face's containing face.

So if you have a face nested inside a Group1 > ComponentInstance1 > Face, then you must add up the transformation of Group1 and ComponentInstance1 and apply that to the point to send to face.classify point.

Thank you, get it! But i dont understand what transformations are applied to a new group (aka what happens when you group entities)?

thomthom

When you group, or make a component, out of existing entities they get their own local co-ordinates within the new group/component. (Within the ComponentDefinition)
The group/component is inserted at the bottom front left corner of the boundingbox of the selected entities. To the grouped entities, this point becomes [0,0,0].
(Though, when you add a group via Ruby API I think the group's origin is set to the current context's origin.)

Here is an English Ivy leaf that works well.

leedeetee

This is probably a ridiculously stupied question but how do I get the ivy leafs to actually show up?! What am I doing wrong?!

EarthMover

CTRL click to bring up the red "+" symbols to indicate where the leaves will go and then SHIFT click to apply and create the leaves.

Instructions are in the last section of the User Interface.

i dont knoe why i have this

Error Loading File LiveIvy.rb
Can't insert empty component.

go to textures folder and convert skp files to version 7. That worked for me...

When I start SU it begins with this:
Error Loading File LiveIvy.rb

This is solved with replacing version 8 leaf components with version 7 in Textures folder...
but still not working:

I try to install the last two version but i still have the same problem.
This message appears when i open sketchup: Error Loading File LiveIvy.rb Can't insert empty component.
Than i'm able to use correctly the plug-in untill the last step.
If i hold click+shift nothing happens. It the same when i only click (generate ivy)

Can you help me?
thanks a lot. Very good work, great idea

sadyo

rabba the components inside the texture pluggin two of them were done in sketchup 8. download the su8 free and resaved the file to su7 or su 6 depends on what version you are using,

majid

just to say a thousand thanx to you Pierre

hi guyz
how is it do this plugin ?
I downloaded it but can not use it
