This application extends the sample "From A View to A picture", and further demonstrates hardware accelerated capture, HD color correction, and movie authoring pipeline from a view.
Again, the contents are 3D animated objects generated using OpenGL The individual (uncompressed) frames during a capture session are written into a framebuffer object. From there, starting with median white-point and color primaries provided by ColorSync for a display profile, linear transformations are computed, HD color correction is applied using a shader, and the results are captured as frames from an offscreen framebuffer using pixel buffer objects. Finally, the frames are written into a movie using QuickTime media authoring interfaces.
