This extension category adds support for node-picking while multisampling antialiasing is active, by defining the interface required by that support.
- (void) closePicking |
Invoked after the rendering pass used during node-picking to restore normal rendering operations.
This implementation does nothing. Subclasses that support node-picking when multisampling is active will override.
- (void) openPicking |
Invoked before the rendering pass used during node-picking, which uses a specialized coloring and pixel-reading algorithm to detect which node is under a touched pixel.
This implementation does nothing other than log an error message if multisampling antialiasing is active. Subclasses that support node-picking when multisampling is active will override.
