### LayerBackedOpenGLView ### |
|
=================================================================================================== |
DESCRIPTION: |
|
The ability to render a Cocoa view hierarchy as a Core Animation layer tree opens the possibility |
of freely combining disparate types of content in ways heretofore difficult. This sample provides |
a simple example of hosting Cocoa controls as subviews of an NSOpenGLView by making the OpenGL |
view layer-backed. |
|
Enabling the "wantsLayer" property of an NSOpenGLView activates layer-backed rendering of the |
OpenGL view. The layer-backed rendering mode uses its own NSOpenGLContext, which is distinct from |
the NSOpenGLContext that the view uses for drawing in non-layer-backed mode. AppKit, working in |
concert with CoreAnimation, automatically creates this context and assigns it to the view. |
|
Additional keyboard and mouse controls: |
Press [space] to toggle rotation of the globe. |
Press [w]/[W] to toggle wireframe rendering. |
Press [c]/[C] to toggle displaying the Cocoa controls. |
Holding and dragging the mouse to change the roll angle of the globe and the angle from which the |
light is coming. |
