The difference with Hawkeye is that a soccer ball is quite big and is virtually-impossible to completely hide from the view of the cameras that are used. Also, a ball is spherical (or close enough), so it will always be the same size regardless of orientation.
Hockey pucks frequently disappear from sight and are small cylinders, a fraction the size of a soccer ball. The centre of a puck could be 1 inch behind the goal line and either be a half inch inside the goal or still have half an inch over the red line depending on its orientation.
A visual system like Hawkeye would be pointless in hockey. Most of the difficult decisions wouldn't be resolvable because you couldn't see the puck. It could be used for offside calls because the puck is usually visible on a zone entry (or zone clear), but not for goals.
For any sort of virtual goal judge system to be useful for hockey, it would need to use sensors built into the puck that reliably provide precise location information (including orientation) multiple times per second.
The technology will probably get there someday, and probably soon, but it's not there now. Tracking player movements to send to an animation program doesn't require anywhere near that level of precision. It's not even close to the same thing.
