WEMExtrude¶

MacroModule¶

genre	`WEMInteraction`
author	`MeVis Medical Solutions AG`
package	`MeVisLab/Standard`
definition	WEMExtrude.def

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.

self¶

name: self, type: SoNode¶: Open Inventor scene for receiving interaction events.

Parameter Fields¶

Field Index¶

`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.¶
