elecstorm Posted July 28, 2014 Share Posted July 28, 2014 Hi! I want to calculate gradient field in dopnetwork. It works perfect, when I do it in gasFieldVop using volumegradientfile node. But when I do the same gradient using gasAnalysis in gradient mode, I have some artefacts on the border. How can I solve this problem?

elecstorm Posted July 28, 2014 Author Share Posted July 28, 2014 This artifact appears with border type "repeat" of the source volume (I use sop scalar field to get it from sop). With mode "streak" it's ok, but I need to infinite repeat this volume to use it in the simulation(. Quote Link to comment Share on other sites More sharing options...
edward Posted July 29, 2014 Share Posted July 29, 2014 I'm not sure I understand. These "artifacts" are the result of computing the gradient using the repeated boundary. So they're basically the "right" gradient values for a repeated volume, and you've indicated that your purpose is to get a infinitely repeated volume. Maybe just want to make sure that the borders of your volume to "wrap around" nicely? Quote Link to comment Share on other sites More sharing options...

It is strange, because source volume in SOP level also has repeate border type (and volumegradientfile sample it correctly). Hip: https://www.dropbox.com/s/22z2wccgjbbfhx9/gradient.hipnc It's hard - with locked volume. Now I use two fields: one with repeate border for sample this field out of it's boundary. And the same volume with streak border to calculate the gradient field. But I want to understand why it's happeinig.
