Title: Fix Vector3f constructor to improve performance

Don’t use optional arguments: it leads to `null` initialization of
those fields (not 0.0 initialization as it was intended).

Remove dead 0.0 initializers altogether.

Remove occurrence of Vector3f() constructor call with no arguments.
Allocated object was not used anyway.
