Shows how to select (pick) 3d objects using the mouse via Axis Aligned Bounding Boxes (AABB).
Beware that AABB's often represent quite a rough fit and therefore is best used as a quick way to determine if there might be a collision and then utilize a more precise calculation to verify it.
The sample has a first person camera so use 'wasd' to move around and hold 'right mouse button' to look around.
The app can be controlled using:
Key | Result |
---|---|
O | Toggle draw oriented bounding boxes on/off |
B | Toggle draw axis aligned bounding boxes on/off |
N | Toggle draw new plane cross on/off |
F | Toggle draw far plane cross on/off |
