This is a conclusion based on previous statements, that it would be good to focus the energy on improving performance (via SSE, NEON) in math3D, and the statement, that Eigen already has that. So the other conclusion is that currently we probably sacrifice some performance due to not using Eigen nor optimized classes in Qt 3D.
