R_cyph Posted March 7, 2014 Share Posted March 7, 2014 hey, I was checking out your site. You've got some really nice work! I stumbled across your flow field renders and I'm dying to know how you rendered this. I didn't realize you could render non divergent velocity fields! please, do tell http://www.popkafx.com/etc/flowfield03.jpg Quote Link to comment Share on other sites More sharing options...
ikarus Posted March 9, 2014 Share Posted March 9, 2014 You could have PM'ed me this question That render is the result of advecting points a huge number of steps through a base fluid sim's velocity field and sampling the resulting trails into a density volume for render. Volume trail does the job quite nicely, though if you want the high resolution you need to generate a great number of trails to fill the volume adequately. I ended up having a feedback system that would generate a new set of trails and repeatedly add it to a base volume with varying seeds. Colors are just false color based on density. 2 Quote Link to comment Share on other sites More sharing options...
