  1. Comodo: 42 CVEs tracked — 6 critical/high severity. 100% unpatched with Trust Score C. Top weakness: XSS (CWE-79) at 30 instances. Default-deny isn’t enough if patching lags. #Comodo #cybersecurity #infosec

  3. Working on nested triply periodic lattices. Here a Gyroid levelset image is created and two interwoven/complementary surfaces are obtained by constructing isosurfaces for the same positive (white) or negative level (red). In the animation the levelset level is adjusted so the surfaces "shrink away" from each other.

  4. Working on automated quasi-structured hexahedral meshing of branched structures in .

    My current solution features a lot of fun tricks, e.g. ray tracing, distance marching, surface smoothing, Bezier splines, lofting, thickening etc.

  5. Was working on surface closure methods, and was using a torus as a test surface (since it has two "periodic" mesh directions to close over).

    Son: "What yah making papa?"
    Me: Oh I'm using this doughnut to..
    Son: That is not a doughnut! That is the wrong color.
    Me: Okay, let me render it brownish and..
    Son: No, you need to add chocolate too, and sprinkles of all colors!
    Me (15 min later): Got it!

  7. And truncating these (cutting the spikes off) is fun too.

    Here I cut so the upward edge lengths are the same as the equatorial edge lengths. It produces rather pleasing pentagonal rings.

  8. Meet the n-trapezohedron.

    Recipe: put 2*n points around the equator, and 2 more for the poles. Now form n top faces and n bottom faces (all quadrilateral). Now alter the points so that all faces are planar.

    High n-values give spiky diamond like things. But the special case with n=3 produces the humble cube!

    Nice set of equations describing the shapes:

  9. Meet the "Pyritohedron", named after the shapes seen in the crystals of the mineral pyrite.

    These shapes are involved in the Weaire-Phelan bubble structure:

    I am working on these as I am implementing various foams and lattice structures in

  10. Working on mesh edge angle analysis in . Left is the @FreeCAD model, right is the mesh edge angle analysis. This will enable surface feature segmentation, e.g. top, inner, sides etc.

  12. Comodo Free Antivirus includes many high-end bonus features, but independent antivirus testing labs have little to say about it, and it fares poorly in our own hands-on tests.

  14. To Comodo’s free antivirus, Comodo Internet Security Pro adds a malware protection guarantee and a full-featured firewall. You don’t get a lot, but you also don’t pay a lot.

  16. And before you know it we have like parametric fillet definitions!

  17. Creating a round on an edge or curve is common in and is often referred to as filleting. The below animation is work in progress to fillet arbitrary curves in 3D space. The local edge cross product helps define the local plane orientation. The local edge lengths in turn help define the maximum radii possible.

  19. Working on extruding or "thickening" meshes from surface elements to layers of solid elements. Here the test mesh features quads (left) which are thickened to produce hexahedral elements (right).

    This is especially handy when one wants a high quality structured mesh of a thin structure. For instance meshing of blood vessel like structures.

  20. Generalised for any surface mesh type now too, e.g. quadrilaterals.

  21. Extending #Comodo to include lattice structure capabilities. First up, "dual cladding". Step 1 here is to shrink each face towards its centre, step 2 is to add new faces connecting the edges that "shrunk away" from each other.
    In the limit where the face is fully contracted to a point, the connections become lines and we obtain the dual graph of the input surface.

  22. Working on adding "non-linear lofting/sweeping". Like with #CAD a section is pulled along a guide curve (sweeping) and the section may change shape (loft).

    Handy for making custom pasta shapes too.
