Volumes 101 - Point Advection
Added 2017-11-24 10:25:16 +0000 UTCAs a quick interlude before we're gonna dive into the ins and outs of wrangling volumes in VEX and OpenCL, here's some relaxation for our eyes: Building abstract line art using point advection.

Interesting that @name=="vel" works correctly in the Velocity VDB parameter but @name=='vel' with single quotes does not.

I lost a lot of time to find issue. I am confused and don't understand why vdb analysis necessary needs port 1 and vdb from polygond port 2. vise versa does not work. Thank you!

2019-04-11 05:33:09 +0000 UTCSimply bad (or good?) habit I guess. I'm used to working in VEX and I am mostly confronted with reading volume values from different inputs, so that's what I tend to use. Haven't checked performance wise, might make a slight difference - please let me know when you have any info on that :) Cheers, Mo

2018-04-02 16:42:50 +0000 UTCHi there, out of curiosity: why do you keep volume sampling your first input in the Volume VOP while a simple Bind with proper naming imports your data right away and save the calculations from the Volume Sample ?

Pretty standard :) Cheers, Mo <a href="https://www.dropbox.com/s/ksng7vtsix0wntx/gradient_plus_curl_trails_015.hipnc?dl=1" rel="nofollow noopener" target="_blank">https://www.dropbox.com/s/ksng7vtsix0wntx/gradient_plus_curl_trails_015.hipnc?dl=1</a>

2018-03-11 08:22:02 +0000 UTCMo, to say your tutorials are blowing my mind would be an understatement. Question: What did your render setup look like for this? Thanks!
