  1. animate line offset on copies

    konstantin magnus replied to jonidunno's topic in General Houdini Questions

    Hi Jon, the sweep node gives you lots of control here. I've linked the first point on the sweep's scale ramp with the carve value. Hit play. grow_lines.hiplc
  2. Detail wrangle: string grps[] = detailintrinsic(0, 'primitivegroups'); foreach(string g; grps){ addprimattrib(0, g, 123); }

  3. Split an object by class attribute into separate geometry nodes in Python

    konstantin magnus replied to DHartleRyan's topic in Scripting

    Hi Daniel, maybe this thread could get you started:

  4. How to adjust the width of a point multiple times

    konstantin magnus replied to kenneth0322's topic in Modeling

    Hi Ken, set up a line with zero length, initialize transforms using rig doctor, and shift point positions in a rig wrangle: int class = 0; class += i@ptnum > 23; class += i@ptnum > 87; float spacing[] = array(1.0, 2.5, 5.0); pretranslate(4@localtransform, set(0.0, 0.0, spacing[class])); spacing_dots.hiplc

  5. How to create a pyramid from a point an a grid?

    konstantin magnus replied to catchyid's topic in Modeling

    Triangulate2D node with "restore original point positions" activated.

  8. Textile , Patchwork and Stitches

    konstantin magnus replied to Valentino's topic in General Houdini Questions

    Another variant using some more recent nodes. 00_patchwork.hiplc

  9. Scatter Jittering

    konstantin magnus replied to hanchunghee's topic in General Houdini Questions

    Hello han, the scatter SOP has output attributes (prim num and prim UVW) the can be read by the attribute interpolate-node. Make sure to freeze time after scattering to avoid re-calculation. stick_points.hiplc

  10. How to snap an object to another precedurally?

    konstantin magnus replied to raincole's topic in General Houdini Questions

    Hi rain, isolate the closest point and apply its offset vector to all other points. vector pos = point(1, 'P', 0); vector rest = point(1, 'rest', 0); vector delta = pos - rest; v@P += delta; object_snap.hipnc

  11. Naked eye 3D video - how to?

    konstantin magnus replied to nemsi's topic in General Houdini Questions

  12. How to snap an object to another precedurally?

    konstantin magnus replied to raincole's topic in General Houdini Questions

    Add a point underneath, ray and match its position. match_ray_top.hiplc

  13. Copy geo to connecting edges of a mesh.

    konstantin magnus replied to jlrvfx's topic in Modeling

    Hi @Thoi, you could try to either stick soft bodies to the other mesh surface using Vellum or possibly project curves that deform the squabs using KineFX or a combination of both.

  14. grouped prims on a plane

    konstantin magnus replied to stonegrange's topic in Modeling

    For non-overlapping tiles there are interesting examples on shadertoy like this: https://www.shadertoy.com/view/3styzn tiles_variegated.hiplc

  15. grouped prims on a plane

    konstantin magnus replied to stonegrange's topic in Modeling

    To get overlapping tiles, you could measure and randomly multiply the straight distance to random positions. tiles_overlapping.hiplc

  16. Distance Based Connect Adjacent Points

    konstantin magnus replied to UltraRenders's topic in General Houdini Questions

    With SOPs: Connect adjacent pieces-node, activate length attribute. Blast node set to primitives, group field: @restlength<0.02 With VEX: float radius_min = chf('radius_min'); float radius_max = chf('radius_max'); int pts_max = chi('maximum_points'); float dists[]; int pts[] = pcfind(0, 'P', v@P, radius_max, pts_max, dists); foreach(int i; int pt; pts){ if(dists[i] > radius_min){ addprim(0, 'polyline', i@ptnum, pt); } }

  17. Gradient patterns

    konstantin magnus replied to Librarian's topic in General Houdini Questions

    Extrude inwards and put a sine wave on vertex colors. int pr = vertexprim(0, i@vtxnum); float offset = rand(pr, 123) * M_PI; float shade = sin(@Time + offset) % 1.0; vertex_colors.hiplc
