Setting the scene
The situation: I have 9 markers for an augmented experience showing our Sun and planets to scale. This allows you to put two markers side by side to see the size differences.
The Problem: the key for this is the scale, but because of the sheer scale changes between the first 4 planets and Jupiter it becomes difficult to see any detail of the smaller few,
The fix: when viewing the “to scale” version I will allow the user to touch the planet to grow it to a standard size to allow finer detail to be scene.
The problem, is I don’t know how to code that… and that is now the the journey for this post…..
