Bounding box

Stub

This article or section is a stub. You can help by expanding it.

The Bounding Box is a simple, rectilinear box that should enclose all the Solid and Visible parts of a model; ie. both its Render geometry and Collision geometry.

• Any geometry outside the Bounding Box (eg a Viewcone) will be regarded as NotSolid to Bullets, Line of Sight and Solid Objects.
• It is used only for crude proximity tests so that no sophisticated (expensive) collision tests need to be performed against objects which do not enter the Bounding Box.
• Confirm:The bounding box does rotate when the entity changes orientation: it is, like a hitbox, an Oriented-Bounding-Box, whereas NPC Hulls, etc do not rotate.

• The BoundingBox Constructor is a method of for defining cuboid vertices. By specifying only the "min" and "max" 3D coordinates - representing two diagonally opposed corners of the box relative to a point origin - the other six vertices are implied. This method is used to define Axis Aligned Bounding boxes, Hit boxes, NPC Hulls and Player Hull in code, and is obviously a great deal simpler than listing SMD mesh triangles.
