Geometry

  • The new release of solidThinking Inspire 2016 introduces new technology that is reported to get optimized, generative designs back into CAD more quickly for manufacturing.
  • ZJ Wang (Univ. of Kansas) announced the launch of meshCurve, software for elevating the polynomial degree of meshes.
  • Here’s a nice overview of 3D-CAD in STAR-CCM+ v11.02.
  • Looking for cloud-based, 3D modeling software based on subdivision surfaces? Check out Vectary, currently accepting applications for their early access program. [Now if only someone would explain the magic of Sub-D surfaces to me.]
  • Cyborg3D is new 3D modeling software that combines Sub-D and NURBS.
  • Kubotek reports back from the Design 2 Part event [held in the DFW area] and cites a battery-powered dog pooper scooper as best design.

A Little Bit of Everything

Events

  • The 25th International Meshing Roundtable will be held in Washington, DC on 27-30 September 2016.
    • The call for papers is open and full manuscripts are due 30 May 2016.
    • The IMR is introducing a new Software Track (in addition to their traditional Research Track) for which applied meshing papers are solicited.
    • The IMR is again holding a meshing contest. [The IMR meshing contest is fun and if you’re doing computational work you should enter.]
  • The 12th International Conference on Fluid Dynamics will be held 19-20 December 2016 in Cairo.  [Edited to correct conference name.]

Let There Be Light – And Tetrahedra

When I say “artists who work with light,” the first two names that immediately pop into everyone’s mind are Robert Irwin and Dan Flavin. [That’s who you thought of, right?]

The work of James Nizam is profiled on Colossal under the title “the immateriality of light.” In that article you’ll find examples of how Nizam is able to shape light into geometric forms despite its lack of materiality. See the tet embedded within two pyramids in the image below.

The geometric parallel with meshing is obvious. But the immateriality of light also translates into meshing, not because the mesh itself is a virtual/digital construct, but because it’s the eventual CFD flow solution that’s made material through visualization.

Be certain to visit the artist’s website for more examples of his work.
