exact point oh a rotating sphere
- by nkint
I have a sphere that represents the heart textured with real pictures.
It's rotating about the x axis, and when user click down it has to show me the exact place he clicked on.
For example if he clicked on Singapore and the system should be able to:
understand that user clicked on the sphere (OK, I'll do it with unProject)
understand where user clicked on the sphere (ray-sphere collision?) and take into account the rotation
transform sphere-coordinate to some coordinate system good for some web-api service
ask to api (OK, this is the simpler thing for me ;-)
some advice?
