Roassal Scalability

Hi

 

I have Roassal as speed with 30,000 elements as with 1,000 elements.

But still I have to udpate the view when resizing the window and translating the view.

Does anyone know how to send the view an event when I resize the view ?

 

Regards

Mathieu

Cool!!!!!

You can do this with event, but I have the impression that the camera should trigger the update of the view.

Cheers,
Alexandre

Hi

 

I think I've understood how events work.

It's very speed, with 30 000 nodes it's very nice, and even with 12 000 nodes and 12 000 edges (Object with all subclasses) it is fine more fluent than before.

I'll commit something so that you can try.

 

Regards

Mathieu

The solution here is to draw only visible elements, we keep them in a list which is regularly refreshed ( zoom, drag ...).

I have not yet measure the speed gain, but it is obvious.

 

The gain is during the visualization, not during the layouting.

Hi!

I have a problem when I load the RoassalScalability package. I cannot open an easel anymore.

If I define the following method:

ROViewStack>>viewDo: aBlock
        views ifNil: [ ^ self ].
        views do: [:v | aBlock value: v ].

Impressive, check this out:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
| rawView view |
rawView := ROView new.
view := ROMondrianViewBuilder view: rawView.
"-------------"
"-------------"
view nodes: (1 to: 400000).
view gridLayout.
"-------------"
"-------------"
ROEaselMorphic new populateMenuOn: view.
view open
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

It takes a couple of seconds to opening it, but it moves well!
400 000 elements. Wow...

Apparently, the examples are not visible anymore. Maybe something wrong with the intersections? Do you consider children elements or something?

Cheers,
Alexandre

I still can open easel, it's weird, or maybe I forget to put ROViewStack>>viewDo:  in the proper package (it must be that).

And examples still works, just they disappear at certain positions, I will have a look at it.

It's just like minimap, it does not act as a cameraTranslated, but it is so...

 

And another point, I cannot create a view with more than 50 000 nodes, my VM crashes (I'm under Ubuntu 13.04), so 400 000, sounds like utopia.

 

Regards

Mathieu

It is a question of refreshing camera information, because since you have resized the window (dragging one corner) then it displays examples properly.

Examples work well, I corrected the problem.

But know there is something the minimap. It seems that the minimap draws exactly the same thing as the view so, as we only display visible elements, we only draw what is visible on the view on the minimap.

We should find an other way of drawing the minimap.

Ok, minimap fixed.

Load this:

Gofer new 
	smalltalkhubUser: 'MathieuDehouck' project: 'RoassalAlgorithm';
	package: 'RoassalScalability';
	load

And try examples or anything you want.

If there is a problem tell me.

Regards

Mathieu

I use OSX. Maybe some limitation of the memory?

It works well.
Apparently, when you maximize a window, things they weird. For example, maximize the easel window, and press the examples button
Can you reproduce this?

Excellent work!

Cheers,
Alexandre

Solved.

This problem raised because in ROViewStack>> replaceFirstBy:   the size of the camera was not updated.

Now, the size of the old camera is given to then new one.
