Make line length match width of object directly underneath Oct. 24, 2019, 1:56 p.m.

Thanks for the pointers! Actually, I did not want the line to intersect, just to change its length accordingly. Also, the reference shape was a lumpy riverbed, not just a flat plane, so intersection was possible. What I ended up doing (based on some other pointers from odForce–and not unlike some of the pointers above) was to resample the hell out of my line, ray it down onto the riverbed, use intersect analysis to create points, used an add to create a line from those points, sorted the points, and then used a wrangle to kill everything but the first and last points. That didn't keep the line above the riverbed/reference shape, but at that point it was easy enough to throw a transform there and lift it back up.

There are some points above that are new to me, so I'll dig in now. Thanks again!

Make line length match width of object directly underneath Oct. 21, 2019, 1:29 p.m.

I have a line hovering above another object (in this example, it's just a grid, but it's more irregularly shaped in what I need). I would like it so that the line length matches the width of the object directly underneath, without reorienting the line, and preferably without actually snapping it to the new point (in y).

Ideally, if I could extract a bbox D_XMIN (/MAX) (or a getbbox min.x), but only at the point in z where the line is, then I could just translate the points to that location. I'm sure this is super-simple, but I'm not quite sure how to go about it.

A ray SOP gets me in the ballpark, but presents some problems, as in the pics.


Help/F1 now just pulls up Google Oct. 7, 2019, 11:56 a.m.

I usually hit F1 for help. I just hit the question mark in the upper right hand corner for the first time, and now “help” no longer pulls up “help,” but a tab that searches Google instead of the Houdini help. Since that happened, now it does the same for hitting F1. I've shut down and restarted and it's still doing it. (The tab also tells me it's using an older version of Chrome, which my outside-of-Houdini browser is not.)

How can I get Help to start showing, well, Help again?

I'm running Houdini Indie 17.5.
