Rendering large terrains

Re:Rendering large terrains by zamalek on Monday March 10, 2014 @07:32AM (#7372355)

CLOD is the underlying mesh/LOD technology used in Frostbite (BF3/4). There is a formal paper for it [1]. My coworker is currently making a toy CLOD renderer in C++ and the technology speaks for itself - he's rendering 8K x 8K worth of height-map data at some 200 FPS on some laptop NVidia chip (he will be open-sourcing it in a few months time, so watch this space).

Frostbite goes a bit further (they stream in the height-map etc.) but the bare method used is this. His reaction to me sharing this was quite funny:

> Cool! But… Javascript??! It’s like writing the bible (or your religious equivalent) in glitter and kids crayons… Loses something.

You just can't get oldschool developers away from their beloved languages :).

It's 2014 and Javascript is awesome.

If I ever do anything 3D, it will probably be WebGL. Some industry veterans have reservations against it, but so long as it doesn't look like poop smeared origami, it's OK.

>2014 and javascript is awesome

sort(1,10,5,3)

1, 10, 3, 5

Then there is this.

null == false //false

!null //true

Works as documented.

Ok, pick any other embarrassing design flaw: http://wtfjs.com/

Documented boneheaded decisions are STILL boneheaded.

Sorry, by 'javascript is awesome', I meant 'javascript performance is awesome'.

"You just can't get oldschool developers away from their beloved languages :)." - 1995 is new-school now?

1995 will be 20 years ago next year.
