  1. Organic shape

    I found that using an attribute promotion hack could help to get clean edges, im not sure in every case but seems to work
  2. Organic shape

    Oh i don't know this file, i start from scratch and using few method I have experimented before. You could see mùy details, and i wwill show if i made it work flow around but fit the face curve, not as random and open me more freedom that some method i used before. Your picture, looks like a tribal mask, look as well pretty cool, you could apply some of our Chop magic here , what did you see that article @Librarian? could not find a link to it Boolean method actually have clean edge if you handle it well, just naively thought polycut should also output something cleaner
  3. Yeah, you could also put a cluster point before the voronoi , kind of similar idea @konstantin magnus
  4. Probably as you are kind reseeding no ? @Noobini
  5. FIND NEIGHBORS OF PRIMS HOUDINI

    Thanks @konstantin magnus. Totalyl agree with you on your comment, sadly here the clustering is not based on the voronoi diagram, i know already these tricks but i can't apply it here. Even with clean geo, it could creat some small pocket areas you may not want. Basically how i see will be to loop to eachpiece, if the area or stretch value is under a certain value, look around (point cloud ) to find the neighbour cluster, pick the best one, and change the cluster attribute value of the considering unwanted area. I guess there is not need to shift the cluster value as some will be missing in the total amount. Now will be to vexify this method. Sam thing coudl be apply to merge small group actually. A second probably more tricky point is, how to define "stretched area"? One with quite different ratio? Not easy in a non planar space... At least when you have an artistic approach

    @konstantin magnus @caskal Somethin i found annoying with the polycut is when you want it to use with edge not extract from the existing mesh via voroinoid, cluster or so. Like using curve on the UV space. So far i only to use the same xyzdist(1, v@P) to define the cutting attribute, blur it, and when set to "cut" and "edge" the cutted piece result and edge are not clean at all. I tried to filter with point neighour count to isolate the unwanted point and only get a clean outiline, but it's not working in all case, not really working If when using Konstantin clever wrangle to deform the mesh using a mask between two polycut value, result seem clean, picture 2 but display the edge boundary and you will see the issue... Fuse doesn't solve all Do you guys see what i mean? ________________________________________________________________ Vincent Thomas (VFX and Art since 1998) Senior Env and Lighting artist & Houdini generalist & Creative Concepts http://fr.linkedin.com/in/vincentthomas
  7. FIND NEIGHBORS OF PRIMS HOUDINI

    Building from myself some hardsurface procedural methods, one issue i have.. Is it possible to filter generated clusters? Merging small cluster which area is too small or area too stretched to the most adjacent cluster? Off course, it's also hard to know if the cluster has to be removed or not . I mean in mure term of design, the size should not be the only element to take into consideration, but that's off couse another more complex question Might i ask if that speak to you ? Thanks you ! @Wooshum @3dome @f1480187 @petz @konstantin magnus ________________________________________________________________ Vincent Thomas (VFX and Art since 1998) Senior Env and Lighting artist & Houdini generalist & Creative Concepts http://fr.linkedin.com/in/vincentthomas

    Everyone own few beers to Konstantin, @konstantin magnus you get drunked all you life and one more
  9. Seamless NURBs UVs?

    I misunderstood your problem. If you unchecked imperfect box in the sphere primitive, it will fix your issue vincent.
  10. Another daily houdini experiment. Not much my cup of tea, but Sop Solver with VEX from a grid, no Simulation ________________________________________________________________ Vincent Thomas (VFX and Art since 1998) Senior Env and Lighting artist & Houdini generalist & Creative Concepts http://fr.linkedin.com/in/vincentthomas
  11. Seamless NURBs UVs?

    Nurbs surfaces never have to be seamless.You could just make the parametrisation to be as uniform as possible and because nurbs surface are mathematicaly define , you don't need to project or unwrap to creat UV. To seam in U and V is a totally different thing...
  12. particles along surface: surface moves??

    That should work, try something like this instead and be sure to ever creat a wrangle with vel pointing to x only and define this in the source input. One interesting this is when using the minpos() and grain, some particules here like you could see in my stupid test are sticked to the left, struggle to find their way. only when usin grain but they follow correctly the terrains, stop . Then using attribute interpolate, previous setup same scenario but you get that second picture now... ________________________________________________________________ Vincent Thomas (VFX and Art since 1998) Senior Env and Lighting artist & Houdini generalist & Creative Concepts http://fr.linkedin.com/in/vincentthomas
  13. Inside Out Geo (again)

    Not sure i understand? So you want to reverse the normal the right selection of face isn'it? If you are not able to extract that group before reaching this point or separate and compare the 2 surface area and keep the largest one you could maybe use the intersect function. If you normal are correctly oriented, then if a ray hit another prim then the prim has to be inclluded in the inside group? ________________________________________________________________ Vincent Thomas (VFX and Art since 1998) Senior Env and Lighting artist & Houdini generalist & Creative Concepts http://fr.linkedin.com/in/vincentthomas

    Quote for Emmy award winning cinematographer Andy B Casagrande IV #lava "Here is the Fagradalsfjall Volcano that melted my drone yesterday in Iceland. You’ll notice the drone’s camera sensor slowly melting as the optics degrade near the end of the sequence, slowly going out of focus. I really wanted a straight down shot of the molten lava erupting directly into my lens, but unfortunately all of the drone’s flight sensors had melted by this point. The drone tried to auto-execute a kamikaze emergency landing, literally inside the volcano. I immediately throttled the joystick full speed upwards, but it was just too late. I lost all connection with drone, monitor screen went blank, no signs of life, it was gone. I was super bummed, but accepted the fact that an Icelandic Volcano had eaten my drone & taken back the lithium-ions. Volcanoes are excellent sources of lithium, so I justified the loss as part of the circle of life. But, to be honest, in the back of my mind, I never really gave up & I kept pushing the throttle stick full speed upwards. And then… 77 seconds later the blank screen suddenly came to life & started displaying the drone metadata, and I couldn’t believe it, my drone was ALIVE! I had no visual image transmitting from the drone, but thanks to the flight metadata, I was able to fly blind & navigate VFR style & we got it back!" lava - Copie.mov lava.mp4 lava - Copie.mov
