WEMExtrude

MacroModule

Purpose

The module WEMExtrude allows for drawing a contour onto the screen that is then extruded into the screen along the viewing direction to form a closed WEM.

Usage

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

Details

The contour is drawn in screen coordinates. By means of the projection matrix, this contour can be projected onto the near z clipping plane. By moving this contour along the viewing direction, a 3D shape is created: an extruded WEM. The result is only created in the close neighborhood of the scene bounding box.

Interaction

Use a SoExaminerViewer to draw a contour. Every new interaction creates a new contour and thus a new extruded WEM.

Output Fields

outWEM

name: outWEM, type: WEM(MLBase)

The extruded output WEM.

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

name: self, type: SoNode

Open Inventor scene for receiving interaction events.

Apply: Trigger	Undo: Trigger
Auto Apply: Bool
Clear: Trigger
Filter Sensitivity: Float
Line Color: Color
status: String
Subdivide: Bool
Triangulate: Bool

Visible Fields

Line Color

name: lineColor, type: Color, default: 1 1 0.600000023841858

Sets the color of the interactively drawn contour line.

Filter Sensitivity

name: filterSensitivity, type: Float, default: 0.99000001, minimum: 0.6, maximum: 1

Sets the value to adjust the extruded WEM’s coarseness.

A low value means a high coarseness, a high value means that the drawn contour is extruded without any smoothing.

Auto Apply

name: autoApply, type: Bool, default: TRUE

If checked, the module generates a new output on each parameter change.

Apply

name: apply, type: Trigger

When pressed, the module will generated its output anew.

Undo

name: undo, type: Trigger

When pressed, the last extruded WEM is undone.

Clear

name: clear, type: Trigger

When pressed, the module clears its output (the extruded WEM).

Triangulate

name: triangulate, type: Bool, default: TRUE

If checked, all resulting polygons of the extrusion will be triangles.

Subdivide

name: subdivide, type: Bool, default: TRUE

If checked, the extruded WEM is subdivided, so that no larger triangles appear.

Hidden Fields

status

name: status, type: String, default: Not enough hit points.
