资源说明:A simple OpenGL engine created for a Computer Graphics course
## OSG OSG - Orbital Strike Group or, OSG - OpenGL Scene Graph engine Take your pick. OSG is a simple scene graph-based engine that arose out of a project in a Computer Graphics class at the University of Wisconsin-Madison. Based somewhat on [Irrlicht](http://irrlicht.sourceforge.net/), OSG features support for render to texture (RTT), multiple render targets (MRT), and deferred shading. ### Dependencies Cg shader code, for obvious reasons, depends on the [NVIDIA Cg libraries](http://developer.nvidia.com/cg-toolkit). The Texture class uses SILLY, a part of the CEGUI library, as an image loader. This allows textures to be loaded from PNG, JPEG, and TGA files. GLEW is used to access Framebuffer functionality. ### Version History **0.1**: The result of the second project in CS 559 (Computer Graphics) at the University of Wisconsin-Madison. Essentially just a poor man's Irrlicht with forward shading only. **0.2**: A result of the third and final project in CS 559. The engine now sports several advanced features such as mesh loading from OBJ files and deferred shading. ### License (The zlib License) Copyright (c) 2012 Matt Kline and Michael Sutherland This software is provided 'as-is', without any express or implied warranty.
