geo/M2DMirror

Reflects a 2D shape across a line through the origin.

Manifold Operations

Mirrors each input cross section about the line through the origin whose NORMAL is `axis`. The default (0,1) has a normal pointing up, so the mirror line is the X axis and the shape flips top to bottom.

It REPLACES the shape with its reflection rather than adding one. For the symmetric pair, put a geo/M2DBoolean in union mode after it with the original on the other input.

The line always passes through the origin, so move the shape with a geo/Transform first to mirror about anything else. geo/M3DMirror is the 3D counterpart.

Parameters

Name Type What it does
axis Vector2 The NORMAL of the mirror line, not the line itself. (0,1) mirrors across the X axis, (1,0) across the Y axis, and anything between across the line at right angles to it. The line always runs through the origin.
