michael Posted March 2, 2009 Share Posted March 2, 2009 have you looked at the Ripple solver? http://www.sidefx.com/docs/houdini9.5/nodes/dop/ripplesolver Quote Link to comment Share on other sites More sharing options...
edward Posted March 3, 2009 Share Posted March 3, 2009 A simple version of this from long ago: http://forums.odforce.net/index.php?s=&...ost&p=31426 Quote Link to comment Share on other sites More sharing options...

ykcosmo Posted March 11, 2009 Share Posted March 11, 2009 I used to use the texture to do the displacement with moving the texture for the wake.... hope this helps... Quote Link to comment Share on other sites More sharing options...
ssh Posted October 9, 2012 Share Posted October 9, 2012 Check the attachment for the simplest case. This is done with vex sop that deforms points of incoming ocean geometry. ssh_kelvin_wake.hip 1 Quote Link to comment Share on other sites More sharing options...
ssh Posted October 15, 2012 Share Posted October 15, 2012 More complex(and slower) model. This one takes boat length, width, speed and draught into account. boat_wake.otl ssh_kelvin_wake.hip 3 Quote Link to comment Share on other sites More sharing options...
MisterP Posted August 27, 2013 Share Posted August 27, 2013 (edited) Hi SSH, thanks for the fantastic boat_wake otl and example. I've got a bit of a weird problem in H12.5 where I cannot edit the otl's vex code (it shows up empty). Is there any chance you could paste the more complex vex here? Thanks MisterP Edited August 27, 2013 by MisterP Quote Link to comment Share on other sites More sharing options...

Thanks MisterP I don't think it is a problem, it is probably "locked" like that deliberately. Quote Link to comment Share on other sites More sharing options...

angelous4x Posted July 7, 2016 Share Posted July 7, 2016 hey shhh sorry to be a bother, but i was looking through your tool, but there seems to be an error for the otl you created. something about the vex could not find shader or something. any help Quote Link to comment Share on other sites More sharing options...
ssh Posted July 1, 2017 Share Posted July 1, 2017 Made an updated version for Houdini 16, should work for H15 as well. Wake deformation done as point wrangle. Get the scene file here: http://www.shlyaev.com/files/hip/ssh_kelvin_wake.hipnc To see source code look onto point wrangle node. 3 Quote Link to comment Share on other sites More sharing options...

Hi Sergey, pretty cool job, did you use any paper to get the formulas or did you figure it out? in case you use any paper, would you mind to share them to check them out? Thanks very much.

kan2211 Posted July 1, 2019 Share Posted July 1, 2019 (edited) @ssh I'm trying to do this set up but unfortunate the link you provide to your site is not working and open ver 12.5 give me error (I'm using 16.5 nc). So if you still have the file could you upload here or anyone in the topic have the file could re-upload, it would be great. Thank you Edited July 1, 2019 by kan2211 Quote Link to comment Share on other sites More sharing options...
ssh Posted July 1, 2019 Share Posted July 1, 2019 (edited) Sure. Attaching file for Houdini 17. This should work in Houdini 16 as well. Let me know if something does not look right. ssh_kelvin_wake.hipnc Edited July 1, 2019 by ssh 3 Quote Link to comment Share on other sites More sharing options...

polterizer Posted April 8, 2020 Share Posted April 8, 2020 hey sergei nice job that, how could you puit them as disappering by age distance or something instead of generating infinity waves? thanks and good job! cheers Carlos Quote Link to comment Share on other sites More sharing options...
ssh Posted April 10, 2020 Share Posted April 10, 2020 Hi Carlos, As far as I remember this geometrical model assumes infinite waves. However, for practical reasons it's good to have it disappearing. I've made updated version, check "Max Distance" parameter. ssh_kelvin_wake_v02.hipnc 7 Quote Link to comment Share on other sites More sharing options...
