Thank you for your comment :)
In the ne...Hi Mr.ED,<br /><br />Thank you for your comment :)<br />In the new Pencil Sketch 4 effect, I have already put a fixed number as the seed for the pseudo-random number generator. You can test this by running the effect twice on the same image, with the same parameters. You will get the same result every time. However, if you move one of the sliders, you will likely get a different result, so you will lose time-coherence (which will indeed produce flickering if you're doing animation). Sorry about that, but due to the way my algo works this is unavoidable.<br /><br />Best regards,<br /><br />David Davidhttps://www.blogger.com/profile/11093317483619075072noreply@blogger.comtag:blogger.com,1999:blog-4977258159897467226.post-23241604053152859262014-03-31T17:28:02.594+02:002014-03-31T17:28:02.594+02:00I was wondering if it is possible to apply the bru...I was wondering if it is possible to apply the brushes in a predictive way (same seed for the random number generator). This would make a series of image stable (would not flicker). <br /><br />I don't know how the brushes are implemented internally but it would be great if this was possible. <br /><br />Great work David, I really enjoy using your program !<br /><br />Mr.EdAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-4977258159897467226.post-44265347331617375952014-03-28T16:17:37.545+01:002014-03-28T16:17:37.545+01:00Thanks, Ari :)Thanks, Ari :)Davidhttps://www.blogger.com/profile/11093317483619075072noreply@blogger.comtag:blogger.com,1999:blog-4977258159897467226.post-61144766759691449272014-03-28T16:07:39.598+01:002014-03-28T16:07:39.598+01:00This comment has been removed by the author.Anonymoushttps://www.blogger.com/profile/13600799901612904652noreply@blogger.comtag:blogger.com,1999:blog-4977258159897467226.post-55449763024367565532014-03-27T19:50:33.172+01:002014-03-27T19:50:33.172+01:00Nice idea.

I'm still adding new ideas, so a little curviness in the dark areas is a possibility.<br />Cheers,<br />DavidDavidhttps://www.blogger.com/profile/11093317483619075072noreply@blogger.comtag:blogger.com,1999:blog-4977258159897467226.post-21367005542885317452014-03-24T23:49:35.763+01:002014-03-24T23:49:35.763+01:00That's wonderful!
