Texture atlases - at least for the own avatar

 Description  « Hide
The SL client should work more with texture atlases to improve client performance.
Texture atlases are probably not generally usefull, because the required textures change when you move/travel. Since the own avatar (skin, clothing, accesories) is visible most of the time, and doesn't change textures often, using atlases might make sense here.

Care to explain what a texture atlas is exactly? I'm not sure I quite follow

... I don't see how this applies to SL, makes perfect sense on an old Mario game though. And animated textures already use something like this (though it doesn't seem to be being applied to animated sculpties yet).

I also get a sense that the map already uses this.

This applies to SL as follows, if I understand correctly: Right now we use several textures for our avatars. If those were merged into one texture (upper left head, upper right body, lower left legs), you only need 1 (larger) texture, that would/could/should result in less textures loaded faster.

Thinking about it, it would also be useful if you could take a linkset and make a texture atlas of all the textures used in it. People often use many textures, those all need to be downloaded each time. Even if only a small bit of a texture is used. If you could make an atlas for the entire set, you would bring down the number of textures downloaded every time.

Wouldn't work for linked-sets though, as a script can change a single texture at any time =(

That is true. Maybe a builder could specify which sides of which prims are to remain as they are and apply an atlas on those?
