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
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.
