Quartz Composer Application

Texture                     An application that shows how to use the QCRenderer API to 

                        render a Quartz composition into an OpenGL pBuffer, then 

                        create a texture from it, and use the texture into another 

                        OpenGL scene.

Sample Requirements             The project was created using the Xcode running under Mac OS 

                        X 10.6.x or later.

About the sample                This sample asks the user to select a Quartz Composer 

                        composition for rendering. The application uses two 

                        rendering contexts. One context has the screen as the 

                        rendering target, the other has a pbuffer as the rendering 

                        target. Every time the rendering is triggered, a QCRenderer 

                        with the selected composition renders the image result into 

                        the pixel buffer. The image is then used as a texture in the 

                        first context in an OpenGL quad.

Using the Sample                Open the project using the Xcode editor which can be found 

                        in /Developer/Applications. Build the project and run.
