arcball revisited...
« on: Jun 23rd, 2003, 12:24am »

i was working on a text-cube when v3ga published his version of arcball... it was just-in-time because i had no idea how to implement a mouse-based navigation device for my cube!
 
so thanks to v3ga for showing me the way to quaternions...
 
my version of this 18 year old guy named arcball:

I am very pleased you have used my Quaternions to build your own ! Nice stuff with the Rotate vs ApplyMatrix
As far as I am concerned, here is one of the best ressource concerning Quaternions, it's fully documented :

nice piece of documentation indeed!
 
meanwhile, i've just implemented a new example using time-driven SLERP:
