![]() ![]() I think that I’ve screwed up one of the stride related parameters to my putVar call, and I end up with x+z transposed in the axes labels when visualized. If you look carefully at the images above, you’ll see that the axis labels are wrong. You can also see some of that detail if the opacity of the rendering is turned way down: Here’s a slice taken close to the z=0 plane (but far enough that the “CN tower” portion of the set is not visible) It’s interesting that much of the characteristic detail of the Mandelbrot set is not visible in the 3D volume, but if we slice that volume, you can then you can see it again. Versions: 9.0, 8.4, ice, devel Build Dependencies: cmake, gmake, ninja, qt, qwt, paraview, mpi, netcdf-fortran, blas, lapack, scalapack, mumps, hypre. Paraview has tons of filters available, and experimenting with them is pretty time consuming, but here are some initial screenshots of the 3D Mandelbrot set: Last time I animated slices of the 3D set, but after a whole lot of messing around I managed to save the data for all the interior points of the 3D set in netCDF format, and render the solid using Paraview. To get the usual 2D Mandelbrot set, one iterates with vectors that lie only in the x-y plane, but we can treat the Mandelbrot set as a 3D solid if we remove the x-y plane restriction. If all we require for a 3D fractal is to iterate a vector equation that is (presumably) at least quadratic, then we have lots of options. ![]() Plotting this in 3D was an interesting challenge, but showed that the Mandelbrot set expressed above has rotational symmetry about the x-axis, which is kind of boring. The iterative equation for the Mandelbrot set can be written in vector form () as: Slicing of the 3D Mandelbrot set, and analysis.Some 3D renderings of the Mandelbrot set,.Furthermore, our current application of the reader is the visualization of higher order simulation output which demands for a special representation of the data within a cell.I’ve been exploring 3D generalizations of the Mandelbrot set: We aim at parallelism to be able to process large data sets. This approach allowed us to tap into the powerful reading and rendering capabilities of ParaView, while the reader is easy to install. ![]() The implementation of the UGRID Reader has been designed corresponding to the ParaView plugin architecture. As the UGRID Conventions are increasingly popular with an important subset of the CF community, they warrant the development of a customized tool for the visualization and exploration of UGRID-conforming data. The UGRID Conventions proposed by the UGRID Interoperability group are attempting to fill in this void by extending the CF Conventions with topology specifications. is it a one dimensional network, a 2D triangular mesh or a flexible mixed triangle/quadrilateral mesh, a 2D mesh with vertical layers, or a fully unstructured 3D mesh. However, it is often necessary to have additional mesh topology information, i.e. While they allow storing unstructured data simply as data defined at a series of points, they do not currently address the topology of the underlying unstructured mesh. The Climate and Forecast Metadata Conventions (CF Conventions) have been set for many years as the standard framework for climate data written in NetCDF format. It currently supports the reading and visualization of 2D unstructured triangular, quadrilateral and mixed triangle/quadrilateral meshes, while the data can be defined per cell or per vertex. ![]() We present the UGRID Reader, a visualization software component that implements the UGRID Conventions into Paraview. ![]()
