Downloaded Qt, Visual Studio C++, cloned (or whatever it is called in svn) the BRL-CAD source code.

• 05 May 2020

Fixed the errors that came up and built BRL-CAD from source on Windows, VS2019. Several bugs still remain. A debug assertion failure happens in pix-bw.exe. But I guess this won't affect my project in any way. The builds still take a long time. I guess this is because everything is compiled everytime.

I looked at the possibility of using NMake to build BRL-CAD for Windows because it would not take long as building with VS (CMake was lot faster when I was doing in Ubuntu last year). Also I need to configure CLion instead of VS.

CMake generates the NMake project successfully. But NMake does not work well. It gives an error when building TCL and TK projects. I was changing various stuff and tried to see if it succeeds.

Changing CMakeLists files of tcl and tk modules and a change to corecrt_io.h in windows 10 SDK made the errors with NMake disappear. Archer does not work. Debugging Archer displays that it crashes saying tkhtml.dll not found. Also I was trying to find a bug to solve as the patch Sean asked for. Looked at https://sourceforge.net/p/brlcad/bugs/385/. Followed some Qt videos.

I was thinking the only command line way of building using Visual Studio was via NMake. I realized that I can build via the Visual Studio IDE's native way by setting some arguments in CMake. Also realized that the build times were long when building with VS IDE was because I built ALL_BUILD when I should have built only the target I changed. Configured CLion to use VS IDE's tools to build. Everything is working now.

Worked on the patch Sean had asked for. The Create new file in MGED had a bug. It was saving without the .g extension even though .g extension was selected in the Create New dialog box (at least on Windows). I tried to debug this. I realized this was a bug (or a unusual behavior) in Tk framework and cannot be by changing BRL-CAD code.

Then I started to create the feature to open recent files in MGED.

• 10 May 2020

Finished implementing opening recent files for MGED.

The patch can be found here. https://sourceforge.net/p/brlcad/patches/542/

I did not do anything related to the project.

Qt is using qmake to build by default. But can be configured to use CMake too. I encountered several issues when trying to configure building Qt applications with CMake in Windows. I fixed those issues and built a Qt based project with CMake.

• 01 June 2020

Implemented opening a BRLCAD database and saving a BRLCAD database using coreinterface.

Used QGLWidget to display geometry using the display manager I implemented last year. Traversing world with keyboard seems to be broken.

• 02 June 2020

Bug fixes relating to displaying geometry.

Created a class to store and process multiple BRLCAD databases (to support keeping multiple documents opened inside the software)

• 03 June 2020

Implemented fetching objects list from a database using BRLCAD::ConstDatabase::TopObjectIterator. Displayed the list in a QListWidget.

However this does not still display the nested objects.
