3D Selection Vault

Grid Wall

Targets hit by a ray, including fully occluded ones, are copied onto a grid in front of the user for direct selection.

How it works

The user first points into the scene; every candidate along the ray is placed on a 2D grid wall, where the intended object is picked in a second step.
