kandi X-RAY | mesher Summary
Mesher is a novel multi-objective unstructured mesh generation software that allows mesh generation to be generated from an arbitrary number of hydrologically important features while maintaining a variable spatial resolution. Triangle quality is guaranteed as well as a smooth graduation from small to large triangles. Including these additional features resulted in a better representation of spatial heterogeneity versus classic topography-only mesh generation. The paper describing mesher can be found here.

QUESTION
In OpenVDB C++ repository, there is this condition inside VolumeToMesh.h:
...ANSWER
Answered 2020-Aug-25 at 07:20As pointed out by @molbdnilo it is a template not a single function and all the input parameters passed to the template satisfy interfaces/traits needed by template.
QUESTION
I am trying to apply Delaunay_mesher_2::refine_mesh to a set of numbered vertices (i.e. vertex class is Triangulation_vertex_base_with_id_2). I expect that any vertex created in the process should have id()==0. However it turns out to be not the case. Instead, the IDs have various positive/negative values.
I tried using Triangulation_vertex_base_with_info_2, but the result was the same.
More or less my code works like this:
...ANSWER
Answered 2019-Jul-05 at 05:53The id is not set by any algorithm. It give you only a possibility to set it for your needs.
QUESTION
I am using CGAL 4.13 to do some 2D triangulation of an outline. In my case some random data originally read from GeoJSON:
The triangulation is done exactly like mentioned in the CGAL user manual: https://doc.cgal.org/latest/Mesh_2/index.html#title14
But when I fetch the triangles out of the Mesher (via mesher.triangulation()), is do not only get the inner triangles but also some "outer" triangles:
Is there a way to get only the triangles matching to the outlines? Like this:
...ANSWER
Answered 2019-Mar-04 at 07:38The face type of the triangultation has a member function is_in_domain()
QUESTION
I try to integrate cgal library to my python program. I made some test by following diverse tutorial. And I try to do a template but I have an error when I compile and I don't know how to fixe it. I use pybind11 to integrate cgal.
Part of my mesher.cpp code :

Answered 2018-Oct-04 at 08:12My original code which you've used, above, was compiled with Clang rather than gcc. If you read this article https://www.fluentcpp.com/2018/05/08/std-iterator-deprecated/ you will see that there are differences in how std::iterator_traits is implemented for Clang. It seems my code provides sufficient type information for the Clang implementation of iterator_traits to work, but not enough for the gcc implementation.
In particular, the code for TypedInputIterator defines value_type, reference and pointer, but neither iterator_category nor difference_type. Therefore, two two missing typedefs need to be added with the other typedefs near the top of the iterator class:

...ANSWER
Answered 2018-Mar-11 at 16:00I didn't figure out how to modify the mesh to add boundary markers, but I did find a workaround to part of the problem in page 9 of this document.
The idea is to define a boundary condition for each boundary

QUESTION
Given a cubic space, this function searches for the next large empty space, places a marker there, and then quits.
However, the function doesn't even print the check message that exists prior to the loops starting, so i don't know how to debug it. The checking starts at 0,0,0 and spaces outside the voxel are returned as true, so it should default all the first loops and send messages back. The unity.exe process jams and i have to abort it.
Why doesn't it print? What else is wrong with it? Even if it is slow, i should be able to track progress within the loops? why wouldn't it?

QUESTION
I have voxel files of 1billion voxels, every voxel is true/false and is kept in a 1D boolean array.
What is a good way to copy it to disk, for example as bytes/ a 0100010101 ASCII file, where i can read the file back into memory fast and efficiently?
At the moment i can write files to disk using:
...ANSWER
Answered 2017-Mar-09 at 14:12Booleans aren't bit-sized in .NET, so they aren't a good storage for the kind of data you want. Instead, use a BitArray - it still gives you all the manipulation you need (read a single bit value, write a single bit value), and allows you to load and store the whole array in byte[] (up to eight bits per byte). This makes persistence quite easy:

Vulnerabilities
No vulnerabilities reported
Install mesher
Python 3.7, 3.8
Install GDAL development files from package manager (e.g., gdal-devel)
C++14 compliant gcc (gcc 7.3+ is good)
You might need to install vtk-devel from package manager if the python wheels for vtk don't exist on linux. Python 3.9 doesn't have VTK wheels yet on macos
