We have 2 different algorithms here, which can be switched by using setFastIncorrect and setSlowCorrect The first version is faster but incorrect and changes the direction of the camera slightly The second version is correct but needs a plane, intersects it and do some Vec3f calculations, so it is slower some benchmarks for both algorithms: fast way: 70,25s user 0,30s system 168% cpu 41,902 total slow way 69,69s user 0,31s system 161% cpu 43,280 total
the default is the slow algorithm
