Pé de Pinico: Particle persistence with Krita Annotations
http://pedepinico.blogspot.com/2012/07/particle-persistence-with-krita.html
Particle persistence with Krita Annotations. Since we can add grains with physical properties, we can start to work on the hard part: particle selection, collision and animation. However, to do that, we need a way to make the objects created in a stroke to be persistent, since after the paintop is done all objects created during the operation are destroyed. For instance, given a image, its associated grid is created by taking the canvas width and height and dividing each by the number of rows/columns dis...

Pé de Pinico: Granular particles at sight
http://pedepinico.blogspot.com/2012/06/granular-particles-at-sight.html
Granular particles at sight. This week was a little rough, since I had some health issues, but nothing that could stop my coding. :). The simulation had a huge improvement when I changed the integrator. I was using the fifth order Gear's predictor and corrector integrator. Since most of the people in real-time applications says that the fourth order Runge Kutta integrator is the most effective, I implemented and saw what they where talking about: it's really fast! When most of the previous errors and dra...

Pé de Pinico: A more dynamic pouring
http://pedepinico.blogspot.com/2012/07/more-dynamic-pouring.html
A more dynamic pouring. Another news is that we can't use the QGraphics Framework due to performance issues. The framework make the selection and collision more easy to handle, but it's really slow for what we had in mind, so I will work on my own code for that. Great job Francisco. Were back on track, blogging regularly, and the brush is starting to come to shape, I have no doubt it will turn out great =). Great Chicão, muito foda! Assinar: Postar comentários (Atom).

Pé de Pinico: Granular particles update!
http://pedepinico.blogspot.com/2012/05/hello-again-ive-been-fooling-around.html
I've been fooling around with my granular particles repository these past days before do a real coding into Krita. I'm trying to optimize my simulation through a series of modifications in the code I wrote last week. My first attempt to run this granular particles simulation was quite a big failure, since it was really slow and full of errors. I correct some small things this past weekend and during this week I implemented a neighborhood restriction to the collision detection between particles. I know it...

Pé de Pinico: Some news of the sand brush
http://pedepinico.blogspot.com/2012/07/some-news-of-sand-brush.html
Some news of the sand brush. It's been a long time since my last post. Lots of things happened since then: I got sick, start a chapter in my university project, finished my short experience as teacher, saw family and friends. and kept working on the sand brush (just forgot to blog about it :P). The project changed a few things for the sake of simplicity. Since the brush have some similar aspects with games, I'll use the Qt4 Graphics Framework. Oh, Krita has nodes?

Pé de Pinico: Performance improvements :)
http://pedepinico.blogspot.com/2012/08/performance-improvements.html
For the first time, I accomplished good performance improvement in a code after refactoring and commenting the code. This kind of practice really helps to clarify an implementation. The KisSandPaintOp reads and writes all the particles from the annotation ans save them as the SandBrush add new particles. There are some other things that is missing, but is easy to be done:. Have to add the "mouse particle" settings, mostly the physical properties like mass, friction and dissipation. The grid customiza...

Pé de Pinico: GSOC 2012: Pencils down
http://pedepinico.blogspot.com/2012/08/gsoc-2012-pencils-down.html
GSOC 2012: Pencils down. Today we have the final pencils down for the Google Summer of Code 2012. It was a wonderful experience do this work along with an awesome team such as the Krita developers. So much learning, and yet so much to be learned, that only a summertime it's not enough. I described some of the implementations we made so far and what is yet to be done. I put a few links to past blog posts that described some of the features developed in more detail. The problems concerning the Pouring.
