  1. VDB Analysis (Laplacian, Divergence)

    @kuvaka here you have some Fine stuff.. https://www3.math.tu-berlin.de/geometrie/wp_padilla/on_bubble_rings_and_ink_chandeliers/
  2. Surface from 2D imported (DXF) shapes, issue...

  3. "Banding" effect on pop sim

    More Experimentos if you change in POINT SOURCE( SOP SOLVER) Dive inside and change first Wrangel in SOPSOLVER #include <voptype.h> #include <voplib.h> int npts = ch("npts"); int seed = ch("seed"); float frame = ch("frame"); int firstpointcount = ch("firstpointcount"); int firstprimcount = ch("firstprimcount"); for(int i = 0; i < npts; ++i) { float r = rand(vop_floattovec((float)i, frame, (float)seed)); int sourcept = (int)(r * firstpointcount); sourcept = clamp(sourcept, 0, firstpointcount-1); int newpt = addpoint(geoself(), sourcept); setpointattrib(geoself(), "sourceptnum", newpt, sourcept); } for(int i = 0; i < firstprimcount; ++i) removeprim(geoself(), i, 0); for(int i = 0; i < firstpointcount; ++i) removepoint(geoself(), i); middle change with this.. and have this outside i@birth = int(10.0 * @Cd.r); for(int sourcept = 0; sourcept < firstpointcount; ++sourcept) { for (int j = 0; j < point(geoself(), "birth", sourcept); j++) { int newpt = addpoint(geoself(), sourcept); setpointattrib(geoself(), "sourceptnum", newpt, sourcept); } } Just found somewhere this HM Fun..file to have FUN test1.hipnc

  22. The Book of Shaders in Houdini Vex

    Hi People! this has a lot of potentials I think sources ---- https://github.com/JosephFiola/BookofShadersHoudiniVex https://thebookofshaders.com Joseph "While Houdini does support GLSL code to render shaders into the viewport, I have not implemented this yet. For now these examples are only visible in the render view using the Ray Tracing render engine." We have examples for 2 and 5 chapters .....if you plug inline-code in CD on Point Vop, you can see everything..and its easy to manipulate.. I am interested to know some process ( Just what to change ) and appreciate help with this. converting rest of some chapters like patterns for example to inline code https://thebookofshaders.com/09/ https://thebookofshaders.com/08/ Thanx
