Ideas and mentors

[Francisco Fernandes]

Hello again!

I just read a email sent by Teo Mrnjavac just a couple hours ago talking
about filling the
ideas page and remembered that I didn't added my idea to the GSoC 2012 page
yet.
Should I do that or the written project should be enough to submit ?

>> Since you don't seem sure how to go about realizing this project, let
>> me tell you that you can implement an effect like this with our
>> infrastructure without need to add a new type of layer to support the
>> particles.
>>
>> Our layers, as you obviously know, store the color channel of each
>> pixel separately, and treats the canvas as a big group of pixels (like
>> any other raster program does). If you think of the canvas as a panel
>> of sand, then you can imagine that in a grayscale layer (which has
>> only 2 channels fer pixel, the black-white channel and the alpha
>> channel) the black-white channel represents amount of sand, and alpha
>> channel is as always just alpha channel.
>>
>> Imagine of ways to simulate your effect using pixels as they are
>> normally used in raster programs. If you can do it this way, you don't
>> need to create new types of layers and you can make your brush work
>> with nothing more than a new brush engine.

>> If you want online assistance you can find me online in the afternoons
