Qt_OSG_OCC-main

This is a simple project demonstrating the integration of OpenCASCADE Technology (OCC), OpenSceneGraph (OSG), and Qt. It provides a basic 3D viewer capable of loading and displaying CAD models (specifically STEP files) processed by OpenCASCADE and rendered using OSG within a Qt application.

Key Features

• OpenCASCADE Integration: Utilizes OpenCASCADE for reading and processing CAD geometries (e.g., STEP files).
• OpenSceneGraph (OSG) Rendering: Renders the 3D models using OSG, providing efficient visualization capabilities.
• Qt Framework: Provides the graphical user interface (GUI) for the application.
• Interactive Viewer: Supports basic camera manipulation (pan, zoom, rotate) using mouse and keyboard.

Technologies Used

• Qt
• OpenCASCADE Technology (OCC)
• OpenSceneGraph (OSG)

Compilation Instructions

This project uses CMake for its build system. To compile the project, follow these steps:

1. Prerequisites: Ensure you have the following libraries installed on your system:

   • Qt (e.g., Qt 5 or Qt 6)
   • OpenCASCADE Technology (OCC)
   • OpenSceneGraph (OSG)
   • CMake
   • A C++ compiler (e.g., GCC, MSVC)

2. Build Steps:

   mkdir build
   cd build
   cmake ..
   cmake --build .

   On Windows, you might need to specify the generator, for example:

   cmake .. -G "Visual Studio 17 2022"
   cmake --build . --config Release
