Many of the textures were created using arcane techniques such as simulated annealing, Voronoi tessellations, and non-linear Fourier-domain filtering. All these methods had to be made suitable for applying to a wrap-around topology. If I were really on the ball, I would have kept the recipes around and made sure that all the textures could be reproduced. But as it is, I think each one gets its own article in the Journal of Irreproducible Results.<br /><br />--Mark<br />Markhttps://www.blogger.com/profile/05314130812566991108noreply@blogger.comtag:blogger.com,1999:blog-8334018989882702842.post-15464734098283963232013-05-07T05:26:34.537-07:002013-05-07T05:26:34.537-07:00Hey Mark.

It never occurred to me you would design your textures algorithmically. That's extremely cool.needlyhttps://www.blogger.com/profile/18009181421142829149noreply@blogger.comtag:blogger.com,1999:blog-8334018989882702842.post-12244233870914317742012-03-03T14:11:14.946-08:002012-03-03T14:11:14.946-08:00Photoshops original Layers implementation was appr...Photoshops original Layers implementation was approximately equivalent To Painters flatters implementation about 15 months earlier. I think we probably came up with very different non-destructive editing capabilities about the same time. Ours had stuff like refraction. Theirs were more like shadows, which we had from the start, but it was an applied effect, unlike photoshops attribute-based method.<br /><br />Great minds think alike, but not always.<br /><br />I chronicle the layer competition in the blog post The Most Useful Painter Feature. There is more in another pat. Just search my blog for Alvy Ray Smith. He, Porter, and Duff were compositing geniuses at Pixar long before I started doing it, of course.<br /><br />Boolean Polygon Operations are a real drag to implement. I think I started in 1976 and continued until 1993 until I got it right.Markhttps://www.blogger.com/profile/05314130812566991108noreply@blogger.comtag:blogger.com,1999:blog-8334018989882702842.post-89004020479406225302012-03-03T00:55:52.199-08:002012-03-03T00:55:52.199-08:00P.S.

I read <a href="http://relativisticobserver.blogspot.com/2012/02/miracle-of-paint-can.html" rel="nofollow">The Miracle of the Paint Can</a>.<br /><br />When I was debugging low-level Painter code, I often didn't know what algorithm the code was supposed to be doing. I had to figure it out just by looking at (tersely or undocumented) code, which was sometimes assembly language. I remember one bug in (C code for) a deeply nested recursion of unraveling the grain (or something) that I nailed just because I recognized a pattern in the code, even though I really didn't know what the code was doing in the overall scheme of things. So I am very interested in reading about the algorithms I was debugging ;) And generally interested in your clever algorithms.<br /><br />I do believe having to reverse engineer algorithms, improved my skills as a programmer. It was an exciting time. Also, the internet was just blooming mid-1990s.shelbyhttps://www.blogger.com/profile/04192118408905938326noreply@blogger.comtag:blogger.com,1999:blog-8334018989882702842.post-7984148592407040532012-03-01T11:41:59.638-08:002012-03-01T11:41:59.638-08:00You are totally welcome!

It was a very busy time for about ten years there, working day and night to continue to keep it cool for the users of Painter. Funny how, even with the turbulent times (IPOs, mergers, acquisitions, obnoxious board members, skeptical venture capitalists) we were able to forge on. It always seemed to me that the only ones outside the company who got what we were doing were the artists and designers.<br /><br />I got a big charge out of showing stuff for the first time. I'll see if I can find some pictures of how it was to actually demo this stuff to giant crowds. Never a dull moment!Markhttps://www.blogger.com/profile/05314130812566991108noreply@blogger.comtag:blogger.com,1999:blog-8334018989882702842.post-1801638378788451152012-03-01T09:14:53.295-08:002012-03-01T09:14:53.295-08:00I an enjoying your site immensely.

I didn't know about Painter until around the middle of 2008, but I love the program. I wish I had known it back in the early days. Thanks for sharing.Anonymousnoreply@blogger.com
