Hehe, I should have be direct the first time. You are positive trolling. Your post is just spamish technical uninformative bullshits.
>> these are sent to the client separately
in different socket packets? in different ports? in different 'gameobjects'? in different 'line of caches'? in different 'structs'/'classes' or in different meshes? sorry but in this case, meshes and classes are not 'send-able' into a network...
>> merged in the graphics card
sorry but graphics cards have no "merge" function at all - I mean, it has no sense again.
The client is the WebGL application running in the user's browser. It requests the appropriate data from the Nokia's server for the area that the user is looking at. This is what I mean by "being sent to the client".
By "merged in the graphics card" I mean that the final image is composed in the graphics card.
Have a look at vterrain.org to get an idea of how these things work.
You were going to deceive people with an aggregate of technical non-senses and obviousnesses mixed with some good links.
I knew that your initial post was as empty as what you are saying now: the server is sending data (and the right one bob!) to the client, then the graphics card is composing the images (Dude!) and the cpu is executing some special instructions.
Good-Boy, right?
But.
It's a fact, people penalized me. I understand, (ultra)positive attitude is prefered over kindof technical and scientific honesty and demand. Even my bug report has been down-voted a lot =) Bugs are negative gnaaaa :>
I'd suggest that you probably got downvoted for saying things like "This is just false ... There is actually no benefit to explain why ...". Most of your responses provided very little information other than to disagree with the post you replied to.
Technical corrections can add a lot of value, but that kind of attitude overshadows any useful value you might have added to the discussion, and it makes it look like you don't intend to add any value at all. Effectively, it made your entire post look like a verbose "Nuh-uh!".
Install WebGL inspector http://benvanik.github.com/WebGL-Inspector/ and you can see exactly what batching and draw calls are used in Nokia 3D maps :-)
