🌟 GLVis 4.3 Released

[tzanio]

Dear GLVis community,

Version 4.3 of GLVis was released on August 7, 2024. Some of the new additions in this release are:

• Visualization of quadrature data (QuadratureFunction in MFEM) in three modes available via the Q key:

  • Piece-wise constants on a low-order-refined (LOR) mesh (the value in each LOR element is given by the unique quadrature point in it)
  • Interpolation (use the quadrature point values as degrees of freedom of an L2 function)
  • L2 projection (compute an L2 projection from the given values)

  See the new Visualizing Quadrature Data section in the Options and Use page for more details.

• Improved auto refinement algorithm which now takes into account the order of the data (mesh and grid function). For more details, see the Auto-refinement section in README.md.

• Added option to specify the floating point number formatting in GLVis axes (key Alt+a) and colorbar (key Alt+c). Formatting can also be specified in socket stream or GLVis script with axis_numberformat or colorbar_numberformat, followed by a C-like formatting string, for example colorbar_numberformat '%+06.1f'.

• Support for scalar integral finite elements.

• Support for 1D elements embedded in 2D and 3D.

• Added a building option for setting the default font size.

• Significantly improved memory usage.

• Various other bugfixes and improvements.
