[...] Fun with Krita: Spray I coded some funny stuff for a paintop called spray. The idea behind it was that I wanted to add a “killer” feature to krita — spray that behaves like MS Paint spray. But then I added support for anti-aliased pixels, then I added support for shapes and it started to be fun, so I added more features. [...]

I just want all these variables to be able to be hooked up to tablet pressure.

That is all.

@maninalift: Good ones, I will try some of them

@Svempa: Could perhaps be neat if one could use random colours
I have got already code for it, but I need to find out how to integrate it into spray

Could perhaps be neat if one could use random colours (like, “I want the hue (or red component, or whatever) to change randomly within a span of X%). Or maybe not. I have some trouble visualizing the results.

> It would be cool if rather than merely specifying “radius” you could select a distribution for your spray, then set the parameters. e.g. “Gaussian”, then set [std deviation] (spread) (or better a general 2D Gaussian: set [angle of major axis], [eccentricity] and [standard deviation]), or “uniform rectangle” then set [angle] [length] [width], “uniform ellipse” etc.. You could even have a spray that spits out points according to a monochrome bitmap ( )

> You could also have a selectable functions for the orientation of particles.

> Particles themselves are just a thing rendered at a given point at a given angle (at a given intensity ?) and so I guess could be rendered with (any?) krita brush

There is loads that could be done. fun fun fun.

Oh… also you could add global randomness / variation… a flexible way to do this is to make it so that any variable that you can modify can either be “static” i.e. you just input the value as normal or you can select from one of a set of dynamic options (sinusoidal, memoryless random, constrained diffusion… )

aaaaaaaaaaaaanyway

ZBrush looks more like a 3D sculpting tool. You may be interested in Blender, they have some similar tool available called Sculpt tool. See http://www.vimeo.com/1221926
Krita is for 2D painting. Maybe with 3D brush in future

It would be cool if Krita could do brushes like ZBrush http://www.pixologic.com/home.php

How difficult would this be do you think?
