Hi everyone.

This is my problem.

I have created a CIContext using OpenGL context to draw some CIImage.

It looks like this:

drawContext = [CIContext contextWithCGLContext:[OpenGLContext CGLContextObj]

pixelFormat:[PixelFormat CGLPixelFormatObj]

options:nil];

At this point, I have done this thing:

[OpenGLContext setView:myNSView];

Here , myNSView is an instance of the NSView class;

However, when I used the drawContext to draw some CIImage object, the myNSView didnt display anything. Can someone tell me what probably goes wrong here? Or under what occasions should we use the CIContext class method "contextWithCGLContext" ?

I am wondering what can we do via creating a CIContext via the OpenGLContext.

Cheers. Thanks for any help.
