  1. @caskal That could be usefull? //The match function return 1 if the string attribute match a string, else is 0 int i = match("name", s@group); After if you could keep thing simple my friend if you start by the choosing the background color, you could define a limited random limited range of color from that, picking the opposite for example (reverse the color) or at least offset in hue for the Hat and i guess the other pig element too. Excepted if you want a black pib on a black background with glowing eye , that might be the coolest I might do some NFT one day i have to ask you few things about, look like fun and, here's it might be a good break from film or TV serie work i did few more research by the way in my spare time, have a look https://www.linkedin.com/pulse/some-my-houdini-procedural-design-research-vincent-thomas/?lipi=urn%3Ali%3Apage%3Ad_flagship3_profile_view_base_post_details%3BuMEv5v6bRTiIcDy%2BQu2%2FLA%3D%3D ________________________________________________________________ Vincent Thomas (VFX and Art since 1998) Senior Env and Lighting artist & Houdini generalist & Creative Concepts http://fr.linkedin.com/in/vincentthomas
  2. Hi ! @Atom maybe you know this one... Im trying to identify which nodes make the size of a file huge, is it possible to loop to all parent node and subnetwork child and look for stashed or locked nodes in python? give back the absolute network path for example... Cheers, vincent* Watched Matrix trailer yesterday and makes me want to play with the primitive sphere a bit...

  3. MOPs v1.5 now available

    Doesn't MOP reorient compute a better bounding box orientation that the one generate the Sidefx bounding box? Which is non correct...
  4. MOPs v1.5 now available

    Yes, this is not a trivial isn'it Henry @toadstorm? Especially if you need precision and stability to handle that procedurally Here one example
  5. MOPs v1.5 now available

    Impressive all you have accomplished with MOPS ! @toadstorm Talking about axis, matrix, edge, orientation pivot something MOPS have built many tool, might i ask you, what will you do yourself to orient resulting pieces of a 3d voronoi fracture (clustered piece or not) so for example if i select every N piece of then, they will find the right edge to rotate, rotate around with the local matrix built? Have you ever have to face that Henry ?
  6. This is an example of what i haven't fun with personally... Looks like mostly everyone is only considering Houdini for FX or scene assembly, a pity no? sorry for the Opengl capture, no power or time to make a beautiful render here No uv , only input is this glorious female mesh ________________________________________________________________ Vincent Thomas (VFX and Art since 1998) Senior Env and Lighting artist & Houdini generalist & Creative Concepts http://fr.linkedin.com/in/vincentthomas
  7. Oh my task for this studio is completed Tesan, i refused a couple of jobs, las t one yesterday as i need to rest a bit or i didn't feel exited The example im using is the one used in this forum , just noticing the tangent orientation could go CW or CCW for the curves where the winding have been solved, after on some complex case, i have a bunch of 3d curves in space which will like to orient all in the same direction. in 2d space , you could use a circle or cyl mapping to order then and polyframe, but in 3d space, i haven't found out. Just looking at the I don't have the math.library, What's this line is supposed to do? p@orient;
  8. Trying to have all complex curves network i have to deal with be oriented properly to be able to use a signed distance to cut my mesh precisely without having to increase the mesh density, for this is need to orient my curves properllu. To what i could see in your simple example, while the orientation of the close curves are not correct, the tangent vector are oriently not uniformly in the same consistent direction, like for the mouth . I try to sort but didn't solve , any idea? @petz
  9. Custom Raytracer in COPs

    Sexy fish @konstantin magnus Something i have been thinking, is to be able to sample in 3d space all decals or texture bombing stuff so the mesh will inherit the normal from then, and dynamically update build its normal map or eight color from that.. Do you see what i mean @konstantin magnus? I know i could sample the color and so in point space, but obviously everyone will prefer not to have a very high density mesh to get correct sampling result, so i picture this more on the shader based context... Am i right ? ________________________________________________________________ Vincent Thomas (VFX and Art since 1998) Senior Env and Lighting artist & Houdini generalist & Creative Concepts http://fr.linkedin.com/in/vincentthomas
  10. Extracting Isosurface as Curves

    Now come the same problem to for example compute the gradient. Knowing you could only compute one direction gradient, how will you combine the 3 directions, in a like triplanar way or spherical way (my suggestions above).. that's the hard part, maybe it's also hardly make sense, i though its was What Rival wanted no? @konstantin magnus
  11. Extracting Isosurface as Curves

    Here we go, Rival you own Konstantin's a beer
  12. Extracting Isosurface as Curves

    I was trying to slice the VDB inside its depth and do booleen but can 't get for a now a nice result in a quick way. In the second case, i clip the sdf Im sure there are some way . The two other way i was thinking were - Render a spherical cam inside using depth image, import it in COP and trace the image slice by slice with a solver - work in a flat 2d voxel heighfield base and wrap back ... @konstantin magnus suggestion are always great
  13. Juraj's playground

    The axis doesn't match the bounding box orientation, is it expected ? Also Juraj, The python code seems to fails working with python 3 version, any idea how to fix it? The result is not is so much better and accurate than the oriented bounding box from sidefx ! thanks! @Juraj
  14. Organic shape

    @thui One key of success is in procedural in to start simple. There are plenty or tutorials and example around , after it will depend how much time you would like to spend on it to learn the fundamental without jumping steps and considering houdini like imported a setup and using it as a plugin preset like in any other software... Myself I had to be patient before i start to get some result which i was not fully ashame, as houdini and the way to think was radically different from what my professional carrier path in my life. But im addicted now, and i refused all jobs which is more or less related... I still consider myself like a student, but at 45s, after 23years, i consider myself in everything like a young kid at the school . Honestly you don't need to go to pay tutorial. I never paid any course and follow any school myself, i didn't have to, job cames without . There are already plenty of examples, after it will be easier for you to find your way when you have learned the base than trying to follow someone 's step... At least it's how it works for me, i don't pretend to hold the world truth... The houdini community is one of the best, or just the best. That's also why i survived
