Unity Occlusion Transparent Gradient

Occlusion transparency If there is no gradient implementation method:

1, transparent objects exist in the list

2, each period of time (can each frame, but the smoothness will be reduced) the camera sends a ray to the player, out Hitinfo

3, List and Hitinfo, will be in the list but not in the Hitinfo object into an opaque, list.remove; will be in the hitinfo but not in the list transit becomes transparent, list.add

If there is a gradient, the implementation is more troublesome, the object has two states: into the transparent process, into the opaque process, add two list (intransparent,outtransparent) corresponding to the two states, then maintain two lists can:

1, not obscured, occlusion, view outtransparent, if there is an object, move from outtransparent to Intransparent,outtransparent remove ; If you do not add a new join intransparent

2, occlusion, not obscured, see intransparent, if there is this object, from Intransparent to outtransparent,intransparent remove ; If you do not add a new join Outtransparent
