breadbox Posted February 7, 2013 Share Posted February 7, 2013 (edited) I'm trying to delete points based on a gradient. I create a green gradient and then delete points based on $CG < 0.4 this creates a hard line where I need to create a kind of gradient, so it would be something like: delete a probability range of $CG less than 0.4 and greater than 0.2 What I'm looking for is basically the multiplication of probability factor in the scatter sop which allows you to scatter points based on an attribute, but want to delete them in a delete sop. this hip might explain it better.

acey195 Posted February 7, 2013 Share Posted February 7, 2013 (rand($PT)*$CG)<0.4 or something like: pow((rand($PT)*$CG),20) < 0.0000001 if you want something in between. change the number around a bit to your taste Quote Link to comment Share on other sites More sharing options...
gui Posted February 7, 2013 Share Posted February 7, 2013 (edited) I do this all the time using distance and probability. See the attached images. If u plug a ramp param in the fit output, you can bias the distance... Edited February 7, 2013 by gui 1 Quote Link to comment Share on other sites More sharing options...
breadbox Posted February 7, 2013 Author Share Posted February 7, 2013 totally rad examples. The Vops method is giving me really clear straight forward results. I tried messing around with powers and exponents for a while, although it does work its pretty abstract and sensitive to control the ranges, the vops is pretty straight forward and I can also remap based on point color instead of distance. COOOL! Quote Link to comment Share on other sites More sharing options...
