Mirror

Functionality

This node is used to make general mirroring over geometry. It works directly over vertices, not with matrixes. It offers 3 different types of mirror:

+=======================+=============================================================+ |Type of Mirror |Description | +=======================+=============================================================+ |Vertex Mirror | Based on one single point | |Axis Mirror | Mirror around an axis defined by two points | |Plane Mirror | Mirror over a plane given by a matrix | +=======================+=============================================================+

Vertex Mirror

This mode let us define a center point and a make mirror of the incoming Vertices

Inputs

All inputs are vectorized and they will accept single or multiple values. There is two inputs:

  • Vertices
  • Vert A

Parameters

Defult value for Vert A is equal to (0.0, 0.0, 0.0). Vertices need an input.

Param Type Default Description
Vertices Vertices none vertices to mirror
Vert A Vertices (0.0, 0.0, 0.0) center of the mirroring

Outputs

Only Vertices will be generated. Depending on the type of the inputs, if they have more than one object, then more objects will be outputted.

Example of usage

In this example we use Vertex mirror to mirroring an arbitrary shape. As you can see every point goes through the center point.

Axis Mirror

This mode is used to make mirroring around an axis defined by two vertices.

Inputs

All inputs are vectorized and they will accept single or multiple values. There is three inputs:

  • Vertices
  • Vert A
  • Vert B

Parameters

There is default values for Vert A and vert B. Vertices need an input.

Param Type Default Description
Vertices Vertices none vertices to mirror
Vert A Vertices (0.0, 0.0, 0.0) first point to define the axis
Vert B Vertices (1.0, 0.0, 0.0) second point to define the axis

Outputs

Only Vertices will be generated. Depending on the type of the inputs, if one or more inputs have multiple values, then more objects will be mirrored.

Example of usage

AxisMirrorDemo1.PNG

We define an axis with two vertices and use them to make a mirror. All the points reflect through the chosen axis.

Plane Mirror

This is the most common method of mirroring. We’ll use a plane defined by a matrix.

Inputs

All inputs are vectorized and they will accept single or multiple values. There is two inputs:

  • Vertices
  • Plane

Parameters

Plane has a defult value, but Vertices need an input.

Param Type Default Description
Vertices Vertices none vertices to mirror
Plane Matrix Identity matrix to define the mirror plane

Outputs

Only Vertices will be generated. Depending on the type of the inputs, if one or more planes are defined, then more objects will be mirrored.

Example of usage

In this last case we just mirror the shape over the selected plane, defined by a matrix.
