GltZpr

GltZpr, developed by Nigel Stewart, is an efficient mouse manipulation module specifically designed for C and C++ GLUT/OpenGL programs. The latest version (0.4) of this free tool is a compact 380 KB file, named gltZpr.exe. This makes it an incredibly lightweight addition to any developer's toolkit. It is compatible with a wide range of Windows operating systems, including Windows XP, Vista, 7, 8, 10, and 11.

Categorized under Development Tools and further classified as Debugging Tools, GltZpr simplifies the integration of mouse-based zooming, panning, and rotation into any GLUT-based OpenGL program. The module works through the inclusion of zpr.c and zpr.h files within the application. This addition involves minimal efforts, requiring only two extra lines of code to supply GLUT callback functions for glutReshapeFunc, glutMouseFunc, and glutMotionFunc. These callback functions manage interactions seamlessly, allowing for VRML examiner-style mouse manipulation through the left, middle, and right buttons. Interestingly, the middle button can be emulated by pressing both the left and right buttons simultaneously.

GltZpr handles the OpenGL modelview matrix by responding efficiently to mouse events received via GLUT, ensuring accurate manipulation and user interaction. The initialization process is straightforward – the zprInit() function should be called after creating the window with glutCreateWindow and setting the initial scaling and orientation. This ease of implementation ensures that even those new to development tools can effectively leverage its functionality.

Download GltZpr for free and experience a user-friendly way to enhance your GLUT-based OpenGL applications with advanced mouse manipulation capabilities.
