I'm a beginner in working with CGAL libraries , I tried to run a combinatorial map example qt-creator on fedora after combiling CGAL: #include <QCoreApplication> #include <CGAL/Combinato...

I'm using a library from CGAL which during the linking stage of my code compilation produces a lot of linking warnings of this form: warning LNK4099: PDB 'vc80.pdb' was not found with 'gmp-vc80-mt...

I am not sure whether there is a .Net version of CGAL? The last time I check there is only one CGAL equivalent in garbage-collected language. If would be tremendously helpful if we have CGAL.net. ...

I am trying to find the distance between two points on a triangulated surface (geodesic distance). It looks like a basic operation and is not trivial. So I am wondering if there are any libra...

I installed with brew the CGAL C++ library. After doing cmake . in the first basic example , I do make and I got a sequence of errors, the first one and most important is: /usr/local/include/QtCore...

Suppose that I have a non-simple polygon, how CGAL can help me to partition it into a set of simple polygons? For example, give a polygon represented by a sequence of 2D points: (1, 1) (1, -1)...

When I build the CGAL examples with cmake, I get this note: #pragma message: The practice of declaring the Bind placeholders (_1, _2, ...) in the global namespace is deprecated. Please use <boos...

I found the Computational Geometry Algorithms Library in my search for an algorithm to decompose a concave polygon into the minimum number of convex components. Links off the site and numerous goog...

What is the difference between the CGAL and the VTK libraries? Both incorporate a lot of the standard geometric algorithms. Can anyone list some application domains where the one is preferred over ...

Currently I try to join different parts of the Mesh, which are not connected. From the example I found this ( blobby_3cc.off ). With the keep_large_connected_components and the keep_largest_connec...

I'm trying to make a cube, which is irregularly triangulated, but virtually coplanar, shade correctly. Here is the current result I have: With wireframe: Normals calculated in my program: ...

I have run: apt-get install -y libcgal-ipelets libcgal-dev libcgal-qt5-dev libcgal-demo But when I try and compile a simple CGAL program with cmake using: cmake_minimum_required(VERSION 3.1) pro...

Using the CGAL lib, I'm trying to implement the Shortest Path methods. I've been kind of successful, but the time it takes to map a path is not nearly acceptable, taking up to 1.5 seconds running ...

I am trying to install CGAL. They describe their installation process as ever-so-simple here, section 6.1. When I run cmake-gui and then click configure, I get the following output: CMake Error at...

I am using CGAL's (the latest) KD-tree implementation for searching nearest neighbors in point sets. And also Wikipedia and other resources seem to suggest that KD-trees are the way to go. But some...

Firstly, I am new to CGAL, but program in C++ a lot. I would like to use CGAL to construct Voronoi diagram of points on the sphere. I have implemented one by myself for one of my research, but the ...

I have never used CGAL and have got almost no C/C++ experience. But following Google I have however managed to compile the example "Alpha_shapes_3" (\CGAL-4.1-beta1\examples\Alpha_shapes_3) on a Wi...

I have two polygons (Polygon_with_holes_2) how joining it into thirth Polygon_with_holes_2 I need general solution. Get any polygon_with_holes (or not if empty hole list but still polygon_with_hol...

I need to find a largest inscribed circle of a convex polygon, I've searched many sites and I get that this can be done by using Delaunay triangulation. I found a thread in CGAL discussion with an ...

for a project I need to create an executable that includes all the libraries that I used (opencv, cgal) in order to execute it on a computer that has not those libraries. Currently, this is my CMak...

I'm running into a performance problem for a task I need to accomplish. One of the bottlenecks at the moment is in getting an interpolated field value from an unstructured grid. The slow part is,...

I am looking for an algorithm or library (better) to break down a polygon into triangles. I will be using these triangles in a Direct3D application. What are the best available options? Here is wh...

I am trying to use CGAL to do some Delaunay triangulation. I used one of the CGAL samples to compute a triangulation which includes a height field attribute. The problem I have having is that I ha...

I have installed CGAL using macports. I run CMake on an example and its running fine. So I tried to create a new project and pasted the code I needed from an example. So I have not link the CGAL li...

I ran into an interesting issue when trying to mix clang (Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn, Target: x86_64-apple-darwin14.0.0), c++11 and CGAL (via MacPorts). It seems...
