[Bf-committers] Fwd: knifeless.blend animation

[Bastien Montagne]

Hi all :)

I’ve started working a bit on knife tool last days (reading code, 
playing a bit with it…), so here’s now my proposition about that tool:

*Current state*
Right now, you start it by hitting K and drawing (while K still pressed) 
a lasso gesture (modal part). When lasso is validated, knife cut is done 
(and modal part is finished).

So basically, it works nice and smooth – there are just:
— Some UI tweaks to be done in its panel (to hide “internal” properties 
like cursor or gesture curve, really easy to do).
— Corner-cut pattern to re-enable (works fine for me, so again this is 
not a problem).

*How it should work IMHO*
I’d like to have knife behaving somewhat like transform tools, i.e. hit 
K enters modal, then you can switch options through a modal keymap, if 
you need it, and then draw your cut (either lasso with LMB, or 
straightline with MMB), and cut is done on gesture validating, like 
currently.

IMHO, this would increase usability of the tool (esp. when you have many 
cuts to do, if the default settings are not good for you, having to use 
the UI to set them each time after the cut is painful).

I’ve been playing with this idea, but I have problems, in that gestures 
are designed as “whole” modal funcs (they add a modal handler, have 
their own keymap [well, lasso/lines have none, btw], etc.). And it seems 
quite difficult to have a modal over (or inside) another modal… So I 
guess I’d have to find a way to have gestures without their “modal” part 
of code…

In fact, if we want to have back things like snap to vertices, I might 
as well handle the whole gesture stuff inside knife cut code – which 
means  I’d need acces to some lower-level gesture funcs…

Anyway, I’d like to have your feelings about that proposed workflow 
first! :D
