  1. Surface Curvature

    @petzThank you very much. File is work perfect!
  2. I have 3D scanned Model to work in Houdini. I use Meshlab for make smooth form and find Curvature. If I want do it only in Houdini I can use Smooth Sop but Curvature is problem because Measure Sop give very wrong result. If I use method from this post from Petz - http://forums.odforce.net/topic/26380-vdb-curvature-flow/?do=findComment&comment=152998 - it works good but only if surface is closed. It is not work right on open surface because it use VDB. Is there better way to find curvature direct for Surface as in Meshlab? Thanks!
  3. Thank you Petz! This work perfect for me!
  4. Make Curve In VEX

    Thank you very much Konstantin and Petz! Your method work perfect!
  5. Thank you eetu! I think you are right but how to find exact Position?
  6. Make Curve In VEX

    How can I make curve in VEX? In Documentation I found spline function but I do not understand how to use. I would like to make smooth blend-curve between many lines. Thanks!
  7. I have curve from external Software and I must cut it at very special position. Is there a method how I can find point that is 90 degrees to given plane? I did add Tangent to curve with polyframe SOP but how to find special position? Thank you in advance!
  8. Wire in Node Graph

    Thank you Noobini, that was it!
  9. How can I make wires in Node Graph Window make look like in old Houdini like in Picture? Is it possible in Houdini 16? Thanks!
  10. wrapping geo like Wrap3

    This is very very good File! Thank you Petz. I did not know it is possible with Houdini.
  11. Flow lines

    @petz Thank you very much! This is very great Method and exatly what I needed!
  12. Flow lines

    @Atom Thank you Atom! I will have look at your link. @Gavin Thank you Gavin! I think you are right. It is similar to magnetic vector field. Will look at blog you mentioned.
  13. Flow lines

    Is it possible to make something like Picture in Houdini? Must I use DOP or Particles for simulation? Thank you!
  14. Advanced Math for Houdini

    Thank you eetu and petz! @eetu I did search for Texture Synthesis and found it very informative but i do not know how to translate it to Houdini . Do you have good link or advice where to start? @petz I did first think it is possible to deform mesh as you did in example to get texture follow Vector field. I did not know how complex it is. To much Divergence, Curl, Poisson I do not understand. Thanks again!
  15. Advanced Math for Houdini

    Thank you! I do not understand method but it does sound very complex I try to understand after more reading in math book
