Purpose

The module WEMInteract allows for drawing a contour onto the screen. The portion of the input WEM that falls into this contour is tagged. The input WEM is then split into two halves, where one part is inside the drawn contour and the other part is outside.

Usage

Add the Open Inventor output to a SoExaminerViewer and draw a contour.

Details

The contour is drawn in screen coordinates. The input WEM is projected onto the screen. All nodes that fall inside the contour are tagged. Afterwards the WEM is divided in two halves based on this tagging.

Output Fields

innerWEM

name: innerWEM, type: WEM(MLBase)

The part of the input WEM inside the drawn contour.

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

outerWEM

name: outerWEM, type: WEM(MLBase)

The part of the input WEM outside the drawn contour.

Clear: Trigger
Editing On: Bool
Generate Edges: Bool
Line Color: Color

Visible Fields

Line Color

name: lineColor, type: Color, default: 1 0 0

Sets the color of the interactively drawn contour line.

Clear

name: clear, type: Trigger

When pressed, all drawn contours are removed and the output WEMs are reset to an unmodified state.

Editing On

name: editingOn, type: Bool, default: TRUE

If checked, the module allows for an interactive editing of contours (drawing contours).

Auto Update

name: autoUpdate, type: Bool, default: TRUE

If checked, the module generates new outputs when the input WEM changes.

Auto Apply

name: autoApply, type: Bool, default: TRUE

If checked, the module generates new outputs on every parameter change.

Apply

name: apply, type: Trigger

When pressed, the module generates a new output.

Tag Nodes

name: tagNodes, type: Bool, default: TRUE

If checked, the nodes inside the drawn contour are being tagged; otherwise, they are untagged.

Generate Edges

name: generateEdges, type: Bool, default: TRUE

If checked, the module generates edges for the output WEM, even if the input WEM does not provide edges.

Hidden Fields

status

name: status, type: String, default: All is well.
