Beamcurve offset: the amount of height offset to apply to the projected beam to generate a smoother curve even when the beam is pointing straight.
(光束曲线偏移)：投射光束时应用的高度偏移量，就算在光束径直指向时也能产生一个光滑的曲线。

Because light travels in a straight line through the contours of space-time, a light beam will curve where space-time curves, this curving was first measured in 1919.
因为光沿时空走直线，所以光线在时空弯曲的地方会弯曲。这现象在1919年首次被观测到。

Pointer Cursor Radius: The size of the ground pointer cursor, This number also affects the size of the objects in the bezier curvebeam.
