you have normalize(@ptnum - p0) @ptnum is the integer id of the point, not its position.

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.

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.

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.

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.. )

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?

What XSI|ICE "Project a vector" equivalent on VOPS?
MENOZ replied to rod.vfx.td's topic in General Houdini Questions
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. -
I would say is the laplace operator https://www.khanacademy.org/math/multivariable-calculus/multivariable-derivatives/laplacian/v/laplacian-intuition

Alembic geo not working with Boolean
MENOZ replied to Fireandsmoke's topic in General Houdini Questions
have you unpacked the geo and converted to polygons? -
have you checked the background value?
-
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..

Packed fracture/alembic settings for hierarchy grouped geo
MENOZ replied to flourish's topic in General Houdini Questions
any luck with this? -
i know about this university http://www3.math.tu-berlin.de/geometrie/Lehre/SS17/MathVis/

boolean is not doing that?
-
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
