halfExtents
Half extents are a vector describing half the size of a rectangular box along its local axes, measured from the box’s center to each face. If a box has width W, height H, and depth D, the half extents are (W/2, H/2, D/2). The full size of the box is twice the half extents, and the box’s center plus or minus the half extents yields its min and max corners in object or world space, depending on orientation.
In axis-aligned bounding boxes (AABB), the half extents define the box’s extents from its center along the
Half extents are commonly used to represent collision shapes in 3D engines. They provide a compact description
Relation to inertia, if needed, follows standard box formulas: the box’s inertia depends on its mass and
