Pajarico,

Is Population the number of objects sprayed out over a specific amount of time?

• Tony

It is a way of controlling the number of sprayed items. But I'm not sure how to tackle this. Having time as a way of measuring the scattering of the items has a problem: depending on how long drawing the stroke takes, the density (that's items/unit of surface) of the stroke will vary. Let's say you've Population=50 items/s, if you draw two strokes in 1 second each both will have in total the same number of items (50), but the fact that both strokes were drawn in the same amount of time doesn't grant that they are of the same lenght, so in practice a longer stroke would have a lower density than a shorter stroke.

Now that I think this behavior would imitate more realistically a spray can, since moving the can faster would lead to less paint density (e.g: fever paint dots).

But in other scenarios the ability to set a constant density (regardless of the time it takes to make the stroke or its lenght) could be more valuable. So ideally both modes should be made available ;)

And there could be a third and fourth player: Population controlled by the background lightness and tablet pressure.

Your thoughts?

this is a fantastic blueprint.

I think the SVG representation is obvious but do you mind filling that area in with any further specifics you might want to add ?

either way, i'm a fan. Thanks

Andy

Thanks Andy ;) BTW, apparently you sent the message to me only and not to inkscape-devel, so I'll answer you here. What specifics should I add? The SVG doesn't need anything new, everything created by this tool is already present in Inkscape so is a matter of implementing the tool itself.

PS: I forgot in my starting message about something. When using clone mode, SHIFT+D should point to the item that was first placed on canvas on that stroke. Unless you have something against it.

Regards.
