I'm wondering how scalable the Core Animation layer model is. When a region of a layer-backed view is updated, does the CA system have a way to quickly identify layers for update, e.g. some sort of spatial hash, or does it simply traverse the whole tree looking for intersections? If the latter I would expect that not to scale so well to thousands of layers.
Some sort of indication about this would be a key decision point about whether to base a substantial update of DrawKit on CALayer or whether to stick to "rolling my own". There are lots of compelling advantages to CALayer, but scalability is vital. --Graham _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
