  1. Orient noise pattern along vectors

    Potential flow * curvature -> Color Advection @vinyvince This has changed from the original agenda, so I think you need to start a new thread.
  2. VEX: add point to prim

    @csp Indeed. I've made it even more robust. But this may not be perfect yet. addvertex_v2.hiplc
  3. VEX: add point to prim

    You can add vertices to any edge by converting a polygon to a polyline and then sorting it using Intrinsic UV. addvertex.hiplc
  4. How handle this mushroom shape procedurally ?

    I tried. I couldn't think of a clever way to do it, but I hope it helps. Mushroom.hiplc
  5. Randomly scale down particles with a linear field

    Distance from Target SOP -> Target parameter to Plane. fo.hiplc
  6. How to group prims by similar curvature

    I use a lot of VEX for that example. I recommend trying GroupSOP's "Min Edge Angle" first. sy_Measured Partitioning_test.hiplc
  7. Polybevel, how to round to an actual circle arc ?

    This is the link of HDA I made in the past, how about this? https://www.orbolt.com/asset/ynkr::polylinebevel
  8. Mestela's method was simple and clever. https://www.sidefx.com/forum/topic/62486/#post-277704
  9. If Mass attribute is 0, point will be pinned. So you can do this by controlling Mass attribute. Pin to Target sy.hipnc
  10. Copy and Transforming in COPs

    Random placement using Cellular noise. cop_random_tiling_v2.hipnc
  11. Copy and Transforming in COPs

    It is way to do with Vop cop. cop_tiling.hipnc
  12. If it is a curve extracted from the surface, you can determine the direction with the inner product of the original N and the new N. I am sorry if it is a misunderstanding. perpenticular_tangent_polycut_sy.hipnc
  13. It is another way. However, this method does not work unless it has a structure that can be converted to a mesh. perpenticular_tangent_sy_2.hipnc
  14. constraint orient problem

    Like this? rot_constraint.hipnc
  15. If you connect Transform SOP to Prev_Frame, It scales Linearly. linear_scale.hipnc
