AntoineSfx Posted May 5, 2020 Share Posted May 5, 2020 (edited) Here is the relevant portion of the documentation: Coordinates Normally you will use this operator in the viewer and simply click to indicate coordinates; however, if you need to you can also use a space-separated list of coordinates in this field to specify points. Coordinates can be specified in the following formats: x,y,z Absolute 3D coordinates, with a default weight of 1. x,y,z,w Absolute 3D coordinates and weighting factor. @x,y,z 3D coordinates relative to the previous point in the list. My coordinate list: 0,0,0 -1,1,0 @2,0,0 @-1,-1,0 2,-2,0 @0,-1,0 @-2,0,0 Can someone confirm that it's not working as expected when two relative coordinates are used in a row ? It looks like the algorithm is ignoring the @ sign in the previous coordinates when computing a relative coordinate, which is kind of ironic.

Noobini Posted May 5, 2020 Share Posted May 5, 2020 yeah, seems it's got a mind of its own... Quote Link to comment Share on other sites More sharing options...
Noobini Posted May 5, 2020 Share Posted May 5, 2020 (edited) try this: 0,0,0 -1,1,0 -1,-1,1 @1,1,1 p3 @1,1,1 with the p3, the last point is correct, without the p3.....wut? so maybe the workaround is to punctuate consec @'s with current point, then fuse later Edited May 5, 2020 by Noobini Quote Link to comment Share on other sites More sharing options...

Which I'm doing right now. 1 Quote Link to comment Share on other sites More sharing options...
AntoineSfx Posted May 7, 2020 Author Share Posted May 7, 2020 (edited) This is fixed in Houdini 18.0.460 (basically next daily build) "The Curve SOP will now handle multiple relative references in a sensible fashion."

AntoineSfx Posted February 2, 2021 Author Share Posted February 2, 2021 There is now a "Build Using relative points" in the contextual menu of Curve while building one. Not sure when it appeared, but it could not have existed before they fixed the first bug I mentioned in this thread. Quote Link to comment Share on other sites More sharing options...
