Developing a MOOSE-based Console for arbalest: a first step to merge arbalest and qged

Organization

Abstract

This project sets out to take the initial step in merging BRL-CAD’s two in-development GUIs: “arbalest” and “qged”. The primary objective is to transfer qged’s sophisticated GED console, which works via low-level calls to BRL-CAD’s core libraries (such as libged and librt), into arbalest, while preserving the application’s distinctive clean and easy-to-scale architecture. To support this endeavor, I will also expand BRL-CAD’s new lightweight, modular, object-oriented API, known as “MOOSE”. In addition to these core tasks, I will tackle compatibility issues related to arbalest’s Qt widgets to ensure proper display across different OSs, as well as resolve various GUI-related bugs.
