<h2>Description</h2>
<p>QTCoreVideo102 is a Cocoa application demonstrating how to render a QuickTime Movie using OpenGL and the Core Video texture pipeline.</p><p>This application is the first in a series of applications demonstrating the synergy between QTKit, CoreVideo, and OpenGL.</p><p>QTCoreVideo102 advances the QTCoreVideo101 sample by introducing several reusable classes that make working with QuickTime Visual Context rendering and OpenGL Views easier and more flexible.</p><p>Base Classes:</p><p>• OpenGLViewKit - Allows you to work with OpenGLViews, interact with objects in 3D space.</p><p>• QTCoreVideoController - Request broker between the OpenGL models and the OpenGL views.</p><p>• MemObject - Memory container class.</p><p>• AlertPanelKit - Utility class for displaying alerts.</p><p>Derived Classes:</p><p>• QTCoreVideoOpenGLView - Derived from OpenGLViewKit, concrete view class.</p><p>• QTVisualContextKit - Utility class for maintaining Core Video PixelBuffer and Core Video OpenGL textures.</p><p>• OpenGLQuad - Allows you to instantiate a Quad object as a display list.</p><p>• OpenGLTeapot - Allows you to instantiate a Teapot object as a display list.</p><p>• OpenGLTeapotTextured - Derived from OpenGLTeapot maintains a texture associated with a Teapot surface.</p><p>These classes will be used throughout the series of samples - QTCoreVideo103, QTCoreVideo201, QTCoreVideo202, and QTCoreVideo301.</p>
