  1. Hi all i am currently making my graduation project in Houdini which is a tool that should be able to create a city procedurally. I am still quite new in this area so i am not sure how to solve this problem. I have created points by using a scatter with color as density so the point positions resembles the roads i want to make, next i have made polylines depending on the distance of the points and i have been able to clean most of it with a fuse. My problem is that i want to delete the last polylines that doesn't belong to the road curve but i do not want to delete corners. Thank you in adwance. roadCurveFromPoints.hipnc
  2. Hello! I'm messing around with bullet constraint networks and I can't figure out how to connect a bunch of points to a single point... basically one source point and multiple paths from it towards each packed piece. Connect adjacent node doesn't have this behaviour. The idea is to connect a fractured packed geo with many points/parts to a non fractured packed geo that has just 1 point/part. I know this will requre some kind of wrangle & coding is not my strong point :| ... any help woud be appreciated! Thank you for your time I appreciate it! Attatched a simple scene, it's just missing the 2nd constraint network. polyline_constaint.hipnc
  3. Hello to all! I am currently writing a wrangle-thing in which I'm hoping to generate a random "hair" on every point and make it face the normal of said point. The way I planned it is as follows: 1. create the hair w/ random params on 0,0,0 2. rotate the hair to Normal of the point that it's "generated on" w/ rotate(matrix,angle,vertex) function 3. Move the hair to @P I'm not a hero with vector math, otherwise I'd generate the whole hair thing along a normal. I wonder if I somehow can construct a identity matrix, like one would do with the ident() function, and use that to transform the prim. Is there a way to simply rotate a primitive using something simpler than extreme vector math? sgamhar.hip
  4. Hi I have a straigth line, created by the line sop, and I want to create some Normals for its points. I tried by typing: v@N = @N in a wrangle node, or by using the poly frame sop, now this would normally work, but it seems like the normals cant be created if the curve is completly straigth, those methods works only if the curve has some kind of curvature (not straigth). Why?
  5. Delete inline points

    Good day, I'm looking for a way to delete inline points from a polygon line. Thank's,
