Detailed Description

This is the earth modelled as a sphere. Yes, this probably needs to be an ellipse some day, but not yet. It's a data layer, so it starts off in the layer thread by creating the earth model itself. Once that's done, it doesn't do anything else.

Member Function Documentation

- (id) initWithTexGroup:

(TextureGroup *)

texGroup

Create it like this. It needs a texture group to run. That provides the images and it will generate the geometry.

- (id) initWithTexGroup:		(TextureGroup *)	texGroup
cacheName:		(NSString *)	cacheName

Create it like this. It needs a texture group to run. That provides the images and it will generate the geometry. If you provide a cache name, we'll try to load from there first

- (float) smallestTesselation

Ask the earth layer what the smallest tesselation size for overlaid geometry should be. This is intended to avoid Z fighting
