Hi! I’m Iván Yossi,
I can’t believe I was selected for the Google Summer of Code program for working on Krita. The proyect I’ll be working this summer is on optimizing Krita’s brush mask to work with AVX instructions. These instructions will be coded using the Vc library, a “zero overhead C++ types for parallel computing” that enables to efficiently transform the mask’s generator code to SIMD instructions for vectorization.
Brush masks is a core process in the painting task as it creates the shape it will be imprinted in the canvas. This, depending on brush settings, can be done as much as thousends of times per second. Having this optimized will greatly improve painting enjoyment keeping the brush stroke responsive on bigger sizes.
You can see more details of the proyect here
I’ll keep you posted as te proyect advances.
See you soon :]
