I found a perfectly good answer to this a few months ago, but Ive spent half an hour googling for it, and have found nothing.
I have a scene which contains content. When someone clicks (touches / taps) the scene on one of the meshes, information about that mesh is shown.
On a mobile the meshes are quite small, and it is difficult to get a touch on the mesh first time, so it takes a bunch of taps to actually hit the mesh.
I have two questions here.
the first one is that it is clear that it is possible to make a hit box or otherwise larger bounding area such that it is easier to tap on the object represented by the mesh. I know there is some kind of documentation about this, but I cannot find it, googling on this subject.
There appears to be absolutely nothing at all on “finding the closest mesh to a picking ray, when there are zero hits”. I can think of several ways to do this, but I imagine this must be an incredibly common problem, and Im wondering if I am using the wrong words to google.
luvs and light, thanks in advance for any help
