Boost-Geometry Library - Use within LibreCAD

To all:

What is the level, if any, of implementation of the BOOST-GEOMETRY LIBRARY within Librecad???

I am finishing my readings in C Programming -> with Pointers, Arrays and Data Structures, will finish that this weekend.

Next I was hoping the BOOST GEOMETRY LIBRARY would be a good first step in C++, which I studied 25-39 years ago, along with C.

Look to move from GCC -> G++ -> Qt4 as my development environment.  

How does LibreCAD implement and use, if it does, the Boost-Geometry Library???

Thanks for any help.

PS  
Note that a C array cannot be the point type of a linestring or a polygon.

On account of the above, if I use the boost-geometry library, I will implement the boost array type concept.  Or use the Concept of LibreCAD.

I need to read the posts more.  I will now do a boost search on the forum. To see what is going on,  I read Dr Li's post yesterday on the plug-in issue, it was great to read.

I guess I have gotten an answer to my own question

Hi Joseph,

Currently, we do not use boost geometry in LibreCAD, and we use boost only for boost math: elliptical integrals, linear algebra. I would love to switch to boost geometry, as soon as boost geometry can handle LibreCAD entity types better (circles and ellipses).

We didn't pull in CGAL, because we want to avoid extra deps.

Qt5 is quite compatible with Qt4, so you may start with Qt5 instead of Qt4.

Qt also handles geometry and it's easier to understand than boost geometry from a user perspective. For your purpose, you may want to read about Qt classes: QRectangle, QRect, etc. We use quite lots of Qt geometry stuff, as we already have Qt in deps.

Regards,

Dongxu
