3D Selection Vault

LassoGrid

The user draws a lasso around a cluster with the ray; every object inside is laid out in a grid and the target is picked from it.

How it works

Holding the trigger, the user traces a closed path around the area containing the target. All objects inside the trace, including hidden ones, are shown in a grid layout, and the target is then selected with ordinary ray-casting.
