  1. Vellum Super Rigid Constraints

    http://www.sidefx.com/docs/houdini/dyno/plasticity.html Note It is difficult to make very stiff material in Vellum, such as sheet metal. For very hard materials, use Bullet Soft Constraints.
  2. from time to time i have that problem, I've been burned once and now I don't really trust the spreadsheet's order I always order by another column to force a refresh and have it working correctly again. if you managed to make it reproducible maybe is a good idea to send it to sidefx so they can take a look.
  3. Houdini grooming tools parting lines

    i tried to put the parting lines in the guide groom, (and create a rest sop or it will complain later) and it seems that the hair gen picks it up and part it correctly.
  4. Fusion vs Nuke

    because what applies to you doesn't necessarily apply to everyone else. If cops is enough for your work that's great, someone else might have different needs. (Rotoscoping, tracking, speed.. )
  5. Dense cloud shader (wdas cloud hype)

    to get dark edges you need to use forward scatter in the shader and many bounces of light. even with 8 bounces you can see the effect of dark edges. the more the bounces the brighter it gets because it more likely that the ray bounces back into your eye. From what I can see the math is already there and working, but is a bit slow. Does redshift support multiple volume bounces? is it capable to simulate internal volume scattering?
  6. Intersect VOP gives the coords on a surface, reading the help it seems to me more like dot(a,b)/length(b) https://en.wikipedia.org/wiki/Dot_product wiki calls it "Scalar projection" Never used softimage tho.
  7. local minimum in 3d

    I would say is the laplace operator https://www.khanacademy.org/math/multivariable-calculus/multivariable-derivatives/laplacian/v/laplacian-intuition
  8. Alembic geo not working with Boolean

    have you unpacked the geo and converted to polygons?
  9. Strange VDB bounding box rendering

    have you checked the background value?
  10. Rant about parameter expression syntax

    i think you SHOULD RFE to sidefx, they might come up with some clever idea to simplify or make it more accessible, you never know..
  11. Immersive Linear Algebra

    i know about this university http://www3.math.tu-berlin.de/geometrie/Lehre/SS17/MathVis/
  12. Recompute topology after projection on a plane

    boolean is not doing that?
  13. Houdini 17 Wishlist

    i would love that when you load an alembic file it put the point where the pivot was, not only on the centroid or at the origin
  14. How to avoid double walls created by convertVDB

    i tried this road but i'm stuck: i am trying to find the borders of the mesh with an attribute (I tried with the curvature and with another silly method, both gives the same results in this case) and primitiveSplit them so in my mind i would have the big face on one side, the faces at the borders, and the other side of the mesh. The problem is that this method is very dirty and i would need to create a clean seam line. Once you can separate the 2 big faces you can choose the one you prefer based on some parameters (like occlusion maybe?) and reproject it more or less in the position where the original scattered points were. The problem is to find a cleaner border edge to use to split the prims. maybe there is a good way to find the borders of the original scattered points, I usually count how many neighbours in a radius and use a treshold to filter those particles.. but is not always great, and use those border points to create a line, then extrude and boolean the mesh to split it. I attach the file if you want to have a look... :/ I'm pretty sure there must be some mathy way of finding those features. findBorders.hipnc
