I think it will cost too much performance to convert the CGImage objects to other formats, e.g. NSImage, CIImage. So I am wondering a direct way to draw CGImage to a NSView or NSOpenGLView.

Can anyone give me a suggestion? Thank you very much in advanced.

Have you considered using an IKImageView? Alternatively, have a look at CGContextDrawImage().

You might also want to benchmarking going from CGImage -> NSImage. Depending on the type of images you're working with, and how frequently you would do this conversion, it might be perfectly usable.
