Detailed Description

Cache-friendly container of 4x4 matrices represented as a SoA array.

Remarks: ArrayMatrix4 is a SIMD & cache-friendly version of Matrix4. An operation on an ArrayMatrix4 is done on 4 vectors at a time (the actual amount is defined by ARRAY_PACKED_REALS) Assuming ARRAY_PACKED_REALS == 4, the memory layout will be as following: mChunkBase mChunkBase + 3 a00b00c00d00 a01b01c01d01 Extracting one Matrix4 needs 256 bytes, which needs 4 line fetches for common cache lines of 64 bytes. Make sure extractions are made sequentially to avoid cache trashing and excessive bandwidth consumption, and prefer working on see ArrayVector3 & see ArrayQuaternion instead Architectures where the cache line == 32 bytes may want to set ARRAY_PACKED_REALS = 2 depending on their needs; ArrayMatrix4 is a SIMD & cache-friendly version of Matrix4.
