If you have an x86-64 CPU with SSE3 and AVX instructions, you might want to check my 3D engine, Orka, which provides packages for vectors (4), matrices (4x4), and quaternions. See https://github.com/onox/orka/blob/master/src/orka/interface/orka-transforms-simd_quaternions.ads. Use Orka.Transforms.Singles.Quaternions for 32-bit floats with SSE and Orka.Transforms.Doubles.Quaternions for 64-bit with AVX.
