Im trying to remember the history of TVPaint, given your link, as teh copyright on the bottom of the page says 1997. Im wondering if it was a Windows specific attempt to first replicate, then exceed the capabilities of Deluxe Paint V.
I saw an article the other day about the return of 2D animation, and they were saying, to learn how to draw on a computer, you first have to be able to draw with pencil and paper. Well, I dont know which heap of junk software theyve been using, but being able to draw a perfectly smooth 3 point nonlinear curve for a cartoon character, is a lot easier on the computer, than it is on paper with bad hand eye coordination and minor trembles. Paper is real time, computers allow you to remove the real time requirement, unless you are using real time effects like airbruush, in which case I return to making a toal mess once more.
This is why I am in such awe in anyone who can use a computer in real time.
Now all we need is more research onto convolution matrices for painting styles, material textures etcetc, so they can be dropped in existing convolve code, and then sent to the GPU in a standard harware acceleration wrapper.
