EDIT : Splitted from Mischief Software topic.
Their technology is quite amazing. I was impressed by the performance of the infinite canvas.
One software that really impressed me lately (for animation) is a specialized bucket tool pretty much. It’s called lazy brush
Whats great about it is that it is using a new type of algorithm to figure out how to fill lineart. Their approach takes care of all the laborious tasks when dealing with a standard bucket tool.
The author posted the paper with the algorithm publicly
Some gmic developers saw it and made an implementation called comics colorize
then Krita devs also noticed that and decided to implement support for gmic
The gmic script is nice to have, but it’s still behind the original implementation, missing the ability to do “erase/corrective patches”
Also the original has some nice features specifically designed for dealing with colouring a sequence of images
