sibarrick Posted April 22, 2007 Share Posted April 22, 2007 Does anyone recall there being a stamp cop, way back when? I think it was in the old compositor. Is there a replacement for it, or anyone know of a way to reproduce the effect? The only thing I can think of would be birthing particles based on an image and then using sprites or something and doing a render. All I need is to copy a solid circle to each point in an image where the brightness goes over a threshold. Using the defocus cop kinda works but I want per point control over the radius based on a couple of mask channels. Quote Link to comment Share on other sites More sharing options...
malexander Posted April 23, 2007 Share Posted April 23, 2007 The defocus COP has "Per Pixel Defocus" which should control the radius based on the mask. You can use a Limit COP to remove any pixels below a certain value threshold. You will probably want to either make the source pixels floating point with rather large values, or adjust the boost parameters in the Defocus COP so the circles aren't dim. A contrast COP / limit COP afterwards should be able to make your circles solid and in the 0-1 range. The only other COP do so something like stamp is convolve, which is fairly slow and won't get you the variable radius. Quote Link to comment Share on other sites More sharing options...
sibarrick Posted April 23, 2007 Author Share Posted April 23, 2007 No plans to resurect the old stamp cop? or did i totally imagine that it even used to exist? Quote Link to comment Share on other sites More sharing options...
malexander Posted April 23, 2007 Share Posted April 23, 2007 Yes it did exist. But no, no real plans to resurrect it in the near future. Quote Link to comment Share on other sites More sharing options...
