Sao Chép Ràng Buộc Về Tỷ Lệ -- Copy Scale Constraint

The Copy Scale constraint forces its owner to have the same scale as its target.

Ghi chú

Here we talk of scale, not of size! Indeed, you can have two objects, one much bigger than the other, and yet both of them have the same scale. This is also true with bones: in Pose Mode, they all have a unitary scale when they are in rest position, represented by their visible length.

X, Y, Z

These buttons control which axes of the target scale are copied.

Power

Allows raising the copied scale to the specified arbitrary power.

Make Uniform

Instead of copying scale for individual axes, apply a uniform scaling factor to all axes of the owner that achieves the same overall change in volume.

Dịch Chuyển -- Offset

When enabled, the constraint combines the copied scale with the owner's scale, instead of overwriting it.

Bổ Sung -- Additive

Uses addition instead of multiplication in the implementation of the Offset option.

Không Gian -- Space

Sự chuyển đổi tiêu chuẩn giữa các không gian.

Ghi chú

Since scale is a multiplicative quantity, it should be combined using multiplication, and split into fractions or inverted via power. Thus the use of Power is more mathematically correct than Influence, which uses linear interpolation. The use of the Additive option is also not recommended.

Mẹo

To copy scale from one axis of the target to all axes of the owner, disable other axes, enable Make Uniform, and set Power to 3.
