  1. Volume density based on point position and/or depth

    konstantin magnus replied to TheDude123's topic in General Houdini Questions

    You could remap a signed-distance field. f@density = fit(f@density, 0.0, -0.2, 0.0, 1.0); f@density = chramp('density', f@density); volume_fall_off_test_km.hipnc

  2. Scatter without selfpenetration

    konstantin magnus replied to Maciej's topic in Modeling

    The UV layout node can do this for meshes, eg. from top. pack_2D.hip

  3. Growing geometry

    konstantin magnus replied to RTHMan's topic in Modeling

    Hi Robert, it seems he animated a Voronoi diagram: int pts[] = nearpoints(1, v@P, 1.0, 2); vector pos_0 = point(1, 'P', pts[0]); vector pos_1 = point(1, 'P', pts[1]); float d_0 = distance(pos_0, v@P); float d_1 = distance(pos_1, v@P); float d = d_1 - d_0; d_0 is the distance for driving the growing circles and d is the distance to the cell boundaries. https://procegen.konstantinmagnus.de/voronoi-diagram-reveal voronoi_reveal.hipnc

  5. Pointgroup for Clip Sop Edge

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

    Is there any way to make the clip SOP not fuse both parts? Or do we have to deal with splitting up its above- and below-groups each time?

  6. Dividing cube into smaller ones

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

    Sorry Matt, I accidently set it to 'draft'. It should be available now. It's just a for loop iterating over the vdb resample-node.

  7. [SOLVED] Use Heightfield Erode Node on Regular Geometry Polygon Mesh?

    konstantin magnus replied to bentraje's topic in Modeling

    Hi @bentraje, you could map the surface curvature to the height field. The erosion of the landscape can then be transferred back for displacement. https://procegen.konstantinmagnus.de/height-field-erosion-on-meshes

  8. Dividing cube into smaller ones

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

    Iteratively resampling a voxel field and visualizing the VDB tree as cubes might also be an option: https://procegen.konstantinmagnus.de/cubify-meshes
  9. Hi Vincent, it seems to work on my side. Did you fill the image paths?
  10. Hi Burton, I've attached a more intuitive non-VEX solution. It's basically the same thing. Let us know if you have any questions. laser_cutting_SOPs.hipnc
  11. You could create a curveu attribute and add the primitive number to it. This does not consider varying curve lengths though. ap_km_etch_font_into_grid_u.hipnc
  12. Hi Burton, you could also use the clip node driven by the distance towards the curve along with a time mask for cutting: https://procegen.konstantinmagnus.de/plasma-cutting-along-curve

  13. How do you apply xform attribute info from oriented bounding box?

    konstantin magnus replied to bentway23's topic in Modeling

    Hi Mark, attribute copy + transform by attribute should get you there.

  14. Best way to modelise Microscopic Hair

    konstantin magnus replied to nemsi's topic in Modeling

    Hi Naim, you could displace grids and stick them to a sweeped curve: hair_microscopic.hip

  15. Mesh outlines

    konstantin magnus replied to konstantin magnus's topic in Finished Work

    I've just posted a written article explaining the same technique: https://procegen.konstantinmagnus.de/render-cartoon-outlines-in-sops

  16. UV cubic map procedurally

    konstantin magnus replied to Mzigaib's topic in Modeling

    I have just published the same article on my procedural generation page: https://procegen.konstantinmagnus.de/cubic-uv-projection-in-vex
