Ideas and mentors

[Francisco Fernandes]

Hello everyone!

Francisco, any new way to paint creatively in Krita is welcome.

That's seens very nice! I will think of ways to use your idea to emulate
this effect.
I'm still looking for papers with similar effects, but I believe that most
will use some
gaussian noise and gradient in the direction of the movement of the mouse
to emulate
the spread of the sand, although I think some experiments will be needed
first.

I'm already trying to do some random things in the code-in paintop
template, although
I didn't accomplished anything yet. I'll try to show up in the IRC channel
today so we
can discuss this better. :D

Thanks! :)


Yes, it's a pretty cool idea and since we try to have at least one very

My laptop doesns't have one GPU, but I have access to a computer with a
nvidia graphical card
in my university. Perhaps I can try the knowledge base
tutorial<http://community.kde.org/Krita/OpenCL_knowledgebase>s
there. I believe that will reduce
the gap before the real project begins. :)

Anyway, thanks for the reply! Any news about the idea I'll post
here in the mailing list.

See you around!

Att.
