What is `quarter`

Quarter is a light-weight glue library that provides seamless integration between Systems in Motions’s Coin high-level 3D visualization library and Trolltech’s Qt 2D user interface library. Qt and Coin is a perfect match since they are both open source, widely portable and easy to use. Quarter has evolved from Systems in Motion’s own experiences using Coin and Qt together in our applications. The functionality in Quarter revolves around QuarterWidget, a subclass of QGLWidget. This widget provides functionality for rendering of Coin scenegraphs and translation of QEvents into SoEvents. Using this widget is as easy as using any other QWidget. quarter 1.1.0 4.fc34 x86_64 70 k quarter-1.1.0-4.fc34.src.rpm fedora Lightweight glue library between Coin and Qt https BSD Quarter is a light-weight glue library that provides seamless integration between Systems in Motions’s Coin high-level 3D visualization library and Trolltech’s Qt 2D user interface library.
