# setPixelBuffer:cubeMapFace:mipMapLevel:currentVirtualScreen:

Attaches the specified pixel buffer to the OpenGL context.

## Declaration

```occ
- (void) setPixelBuffer:(NSOpenGLPixelBuffer *) pixelBuffer cubeMapFace:(GLenum) face mipMapLevel:(GLint) level currentVirtualScreen:(GLint) screen;
```

## Parameters

- `pixelBuffer`: The pixel buffer to attach.
- `face`: For pixel buffers with a texture target of GL_CUBE_MAP, this parameter should be zero or one of the following values: GL_TEXTURE_CUBE_MAP_POSITIVE_X GL_TEXTURE_CUBE_MAP_POSITIVE_Y GL_TEXTURE_CUBE_MAP_POSITIVE_Z GL_TEXTURE_CUBE_MAP_NEGATIVE_X GL_TEXTURE_CUBE_MAP_NEGATIVE_Y GL_TEXTURE_CUBE_MAP_NEGATIVE_Z
- `level`: The desired mipmap level for rendering. This value must be less than or equal to the maximum texture mipmap level of pixelBuffer (accessible through an NSOpenGLPixelBuffer object’s doc://com.apple.appkit/documentation/AppKit/NSOpenGLPixelBuffer/textureMaxMipMapLevel method).
- `screen`: The virtual screen of the receiver (if applicable) should be set to the same value as the current virtual screen you are using for rendering onscreen

## Discussion

Discussion The NSOpenGLPixelBuffer object gives the receiver access to accelerated offscreen rendering in the pixel buffer, which is primarily used for textures.
