[Plugin] VisMap - Layer/Scene Visibility Map

MSP_Greg

Martin,

I don't use scenes much, but congrats on your plug-in (I thought you said it was your first somewhere.)

For loading and unloading models, you may want to use the Sketchup::AppObserver and hook the onOpenModel(model) and onNewModel(model) events.

Secondly, you might consider wrapping all your code in a module and use 'self' for the methods, and using 'private' to control for external visibility. Helps with 'namespace type' collisions.

Lastly, I put the html as a string in my rb/rbs files and load it with dialog.set_html. It's easy to change the font size in the (inline) CSS before loading it in the dialog box, and I used 'em' for all the html size/layout units. HTML needs the same kind of escaping as strings passed between ruby and javascript.

HTH,

Greg

I've done a lot with bit maps, so packing 16k bits into a 2k string is not a problem. But is 16k going to handle really large animations? Or should I find (they're there) a more capacious solution?

If you're able to pass it as 32 bits/char, you could get 256^2 bits in. That would work for what I'm trying to do (make a decent pipe system of 200+ pieces and pass it to layout), but might not pass for animation work.

Make it a pro version and a free version, pro being for animation with a different data passing technique?

The limit is 2kB in the URL: 16k bits. I'm working on the code right now to pack 6 bits per byte which you can do with the printable ASCII characters, so it should be totally dependable and give you 12k scene/layer combinations.

I like this thinking!

Thanks for all the good ideas. I'm already pretty clean, namespace wise. (Only one public var, $vismap_model).

That's a very interesting idea!

Martin,

I was referring to procedure / function / class visibility, not variable visibility.

For instance, 'Model' may not be the best unqualified name for a class. IOW, what if someone has a lot of installed plug-ins? You don't want name resolution issues...

Thanks,

Greg

This plugin has terrific potential for my work! I often have 50 or more layers and 10 or more scenes and, although "add hidden layer" is a great help, this plugin would be super for changing things later on in the process.

It worked perfectly with a small test model, but when I applied it to my current large model all I got was a blank dialog box. I tried all kinds of "open, close, scene update, save, etc. tricks", even the right click "reload".

This is on a MacPro.

Works fine for small test model

Does not work for large model (not all layers are shown)

Bob, I am also on a Mac and having a similar problem.
In my case, when VisMap spreadsheet is bigger than dialog box, one of the followings will fix the visibility issue;

Move the dialog box then size-drag to fit VisMap spreadsheet.
Go to another program and come back, then resize the dialog box.
Hope it helps.

See my exchanges w/Edson. Known Mac issue, now tracked to the Ruby code.

Edson,

Drop attachment 1 into your .../Plugins/vismap subdir, open the Ruby Console and try again to vismap "house.skp".

The result should look like attachment 2. (The addresses - :0xhhhhhhh - will be totally different, but the rest will be the same up to the point of the failure.)

Have I thanked you adequately for your help and patience? Both are truly appreciated.

Martin

martin,

no need to thank me. by helping you i am also helping myself and many others who will benefit from your plugin.

i followed your instructions. see the attached file below for the result.

Thanks, Greg. I should maybe learn a bit more Ruby. How does this work?

You click VisMap on your Plugins menu. That's a trivial program that loads ...Plugins\vismap\vismap.rb. How might VisMap stumble onto some other Model class, or some other plugin stumble onto my Model?

Thanks!

That output is perfect. Start to finish, it pulls the data it needs from your model into a correct JavaScript callback. The message doesn't get to JavaScript.

On the PC, this is what I dubbed, The Bug from Hell:

I Love JavaScript (Sometimes)

News: From Business Week Big Blue's Global Labs Building a global chain of "collaboratories." Good luck, IBM. May I loan you my copy of Fu...

(21st-century-languages.blogspot.com)

Just to be sure, there is debugging info commented out in the "rubyReturned" function in "vismap.js". (A JavaScript inline comment is two forward slashes ("//") followed by a comment, or code you don't want to run or a seafood recipe.) Try uncommenting the "// whats_in_model()" function call. Just delete the two slashes. Try Vismap again.

Expected result: nothing. Ruby's callback doesn't call back. Took a week to figure this out on the PC. Why should the Mac be different? (It should be different because it's a Mac, but this is Google code, not Apple code.)

Possible result: you get a pop-up, center screen, detailing "whats_in_model()". Then we have something to work with. Otherwise, ...

The current version now supports about 12k layer/scene intersections.

Mac issues remain.

"Monty", (I say to my pet python) "That's the dumbest idea you've ever had."

"Yeah, hotshot, you got a better idea?"

Lacking an answer, am now trying Monty's suggestion. You never know.

Buggy still, but the problem is in ruby! Here's the console dump on "send to model":

(eval);259; warning; invalid character syntax; use ?\s
(eval);259; warning; string literal in condition
Error; #<LocalJumpError; return from proc-closure>
(eval);259;in `call'

Thanks for the dump. Line 259 is my EOF comment, so I'm not sure what to make of it.

Are you PC or Mac?

If it's PC, can you UL or send me a model? (MartinRinehart at Google's mail service).

Actually, it's in Ruby, but not the Ruby I wrote. See this:

http://groups.google.com/group/sketchupruby/browse_thread/thread/17bff6988f12037b

Google search is one of the wonders of the world. That said, how to find a workaround?

MartinRinehart

Thank you, markozeta, for your pipes! (A big model w/lots of scenes and layers, most helpful for finding the Ruby bug workaround.)

A new version is up. Tested on the PC. Monty, my pet Python, thinks it might work on the Mac, too. Let me know.

Just a heads up, I downloaded the most recent version and got an error hitting the button 'get data from model'

line 157, char 2, error expected '}', code 0

which causes nothing to happen after I continue to run the script on the page.

I haven't read all the posts before this so maybe someone brought it up already but I figured since this was a new version, its a new problem.

markozeta

New to add to documentation:

Only update Vismap with sketchup closed. Updating with sketchup open is bad.

New version works, even on my bigger model!

Now about that alphabetical layer sorting I asked for...

It helps when I can check vismap with a nice straight diagonal for these large maps, since I can just make sure that it works perfect.
