Qt-based Cube Renderer using PicoGL’s GLBase

This example demonstrates how to create a simple cube renderer using Qt’s QOpenGLWidget through PicoGL’s GLBase class. It’s designed for legacy displays and systems that prefer Qt over GLUT.

Features: - Legacy OpenGL rendering (compatible with older systems) - Mouse controls for rotation and zoom - Colorful cube with vertex colors - Qt-based window management - Cross-platform compatibility

Requirements: - PySide6 (Qt6) - PyOpenGL - NumPy - PicoGL

Usage:

python examples/qt_cube.py
