Detailed Description

Cache-friendly array of Aabb represented as a SoA array.

Remarks: ArrayAabb is a SIMD & cache-friendly version of AxisAlignedBox. (AABB = Axis aligned bounding box) See ArrayVector3 for more information.

: For performance reasons given the mathematical properties, this version stores the box in the form "center + halfSize" instead of the form "minimum, maximum" that is present in AxisAlignedBox: Merging is slightly more expensive intersects() is much cheaper Naturally deals with infinite boxes (no need for branches) Transform is cheaper (a common operation)

: Extracting one aabb needs 84 bytes, while all 4 aabbs need 96 bytes, both cases are always two cache lines. Architectures where the cache line == 32 bytes may want to set ARRAY_PACKED_REALS = 2 depending on their needs

Useful when you have a local AABB for an object which is then transformed.

Note: The matrix must be an affine matrix.
