Curved Surfaces

I saw a post Niko on the Irrlicht news and I was wondering... how does this work?

They are simply created when loading quake 3 levels with curved surfaces in it. That's it.

Thanks

, I had to ask because a racing game just isn't right without curves in the race tracks

I'm wondering, is it a special entity thats applied to the geometry before it's compiled into the bsp? I've never worked with curved surfaces before, so I'm sorta at a loss of how to implament them into the level...

they are called 'beizer patches'

basically its a special geometry, though im not sure if its the same as an 'entity', it does require special code to handle though.

Basically (if you're familiar with Beizer Curves) there are some control points (which is what is actually stored in the .BSP file) from which you can estimate where a curved surface would go. You can create a more or less detailed curve depending on how many iterations you want to go over it with. This is generated at run-time during .BSP file loading.

Keless, thank you for that bit of info. When I get back to working with Irrlicht this will be one of the first things I look into
