Hi there,

I want to make a function which will handle multi touch: pinch zoom and rotate camera.

I have determined that tbis is a tricky scenario. Both situations have (at times) positions which are approaching each other. The greatest difference is if they are approaching each other on the same line (will hit - pinch zoom in) or if they are approaching each other but will never hit each other as they are on opposite sides of the screen (rotate cam).

So, if I have two delta vectors, and two corresponding positional vectors… How do I determine if these two will (most likely) hit each other or not?

Hmmmmm

Calculating.
