Hi,

I have an 2d as3 particle physics simulation that uses lots of Math.sqrt, multiplication, distance calculations and collisions detection between 100s of circular vector objects. I want to increase this to 1000s

Is Away3d any good at these calculations or is more a platform to generate polygons quickly and the like?

Regards,
C

For math.abs you have:
private static function abs( value:Number ):Number{ return value < 0 ? -value : value;}

If you are using any kind of raycasting try this function:

(much faster than bresenheim).

Also, have a look at : http://jacksondunstan.com/articles/1217 - he has lots of optimisations on his blog…

and this one:

and don’t take their work for it - test… hope this helped…
