Purpose

The module MarkerListToWEMPlane generates a deformed WEM plane from markers.

Details

The module generates a WEM plane based on a marker list using PCA (principal component analysis). The basic plane is oriented such that the shortest axis of the PCA serves as the normal of the basic plane, while the longest axis of the PCA defines the size of the basic plane (Relative Size = 1).

The basic plane can be deformed by another set of markers. For both tasks, the same set of markers can, of course, be used.

Input Fields

inPCAMarkerList

name: inPCAMarkerList, type: XMarkerList(MLBase)

The markers of this marker list are used to establish the PCA, which influences the main orientation and size of the WEM plane.

For accessing this object via scripting, see the Scripting Reference: MLXMarkerListWrapper.

inDeformMarkerList

name: inDeformMarkerList, type: XMarkerList(MLBase)

The markers of this marker list influence the deformation of the WEM plane.

Visible Fields

Auto Apply

name: autoApply, type: Bool, default: TRUE

If checked, the module computes anew on a change of any fields on the panel.

Update Mode

name: updateMode, type: Enum, default: AutoUpdate, deprecated name: autoUpdate

Defines how this module should react on any input field change.

Values:

Title	Name	Deprecated Name	Description
​Off	​Off	​FALSE	​The output WEM is left unchanged.
​Auto Update	​AutoUpdate	​TRUE	​The output WEM is computed anew.
​Auto Clear	​AutoClear		​The output WEM is cleared (made empty).

Apply

name: apply, type: Trigger

When pressed, the module generates the WEM plane anew.

Clear

name: clear, type: Trigger, deprecated name: clearOutput

When pressed, the output WEM is cleared and attached modules are notified.

Overwrite label and description

name: overwriteLabelDescription, type: Bool, default: FALSE

If checked, label and description strings are set in the output WEM to Label and Description.

Label

name: label, type: String

Sets a label string in the output WEM.

Description

name: description, type: String

Sets a description string in the output WEM.

Generation Mode

name: generationMode, type: Enum, default: Quads

Defines the output WEM generation mode.

Values:

Title	Name	Description
​Quads	​Quads	​Quads are generated.
​Triangles	​Triangles	​Triangles are generated.

Relative Size

name: relativeSize, type: Float, default: 1.2, minimum: 1.1, maximum: 3

Sets the relative size of the initial plane, which is always a square.

A size of 1 means that the plane’s width and height are equal to the largest axis of the PCA.

Grid Resolution

name: gridResolution, type: Integer, default: 40, minimum: 1, maximum: 300

Sets the resolution of the grid or the number of quads per row and column.

Smoothing Passes

name: smoothingPasses, type: Integer, default: 150, minimum: 1, maximum: 300

Sets the amount of smoothing passes of the Laplacian smoothing.

Global Normal

name: globalNormal, type: Vector3, persistent: no

Shows the global normal of the generated plane.

Hidden Fields

isProcessing

name: isProcessing, type: Bool, persistent: no

elapsedTime

name: elapsedTime, type: Float, persistent: no

id

name: id, type: Integer, default: 0

shouldComputeNormals

name: shouldComputeNormals, type: Bool, default: TRUE
