WEMInitialize¶

MLModule¶

genre	`WEMGenerate`
author	`MeVis Medical Solutions AG`
package	`MeVisLab/Standard`
dll	`MLWEMModules`
definition	MLWEMModules.def
see also	`WEMLoad`, `LocalWEMLoad`
inherits from	`WEMGenerator`
keywords	`initialization`, `shape`, `wem`, `surface`, `create`, `generate`, `test`

Purpose¶

The module WEMInitialize initializes a WEM at some position and with some deformation.

Details¶

The module initializes a WEM with a well-formed winged-edge mesh, representing the chosen model. This can be among others, an icosahedron consisting of triangles and a cube consisting of quadrilaterals.

However, for testing purposes, this module can also generate a corrupt WEM or an empty WEM.

Visible Fields¶

Auto Apply¶

name: autoApply, type: Bool, default: TRUE¶: If checked, the output WEM is generated as any parameter is changed.

Apply¶

name: apply, type: Trigger¶: If pressed, the output WEM is generated.

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.

Translation¶

name: initialPosition, type: Vector3, default: 0 0 0¶: Sets the initial position of the WEM.

Scale¶

name: initialDeformation, type: Vector3, default: 1 1 1¶: Sets the initial deformation (anisotropic scaling) of the WEM.

Model¶

name: initModel, type: Enum, default: Icosahedron¶: Defines the model to be used.

Values:

Title	Name	Description
Icosahedron	Icosahedron	A icosahedron consisting of twelve triangles is generated.
Cube	Cube	A cube consisting of six quads is generated.
So WEMDiagnosis Test	SoWEMDiagnosis Test	This model is for testing purposes only and should not be considered a valid WEM!
Empty WEM	EmptyWEM	An empty WEM is generated.
Tetrahedron	Tetrahedron	A tetrahedron consisting of four triangles is generated.
Single Triangle	SingleTriangle	A single triangle is generated as a polygon patch.
Two Triangles	TwoTriangles	Two simple adjacent triangles are generated.
Icosphere	Icosphere	An icosphere is generated. This is a subdivided Icosahedron. Its subdivision level depends on the field `Subdivision Level`.
Octasphere	Octasphere	An octasphere is generated. This is a subdivided Octahedron. Its subdivision level depends on the field `Subdivision Level`.
Dodecahedron	Dodecahedron	A dodecahedron is generated.

Subdivision Level¶

name: sphereSubdivisionLevel, type: Integer, default: 4, minimum: 1¶: Sets the subdivision level of the spheres (Icosphere and Octasphere).

Mirror Faces¶

name: mirrorFaces, type: Bool, default: FALSE¶: If checked, the generated faces are all mirrored so that all face/node normals point inwards.

Generate Edges¶

name: generateEdges, type: Bool, default: TRUE¶: If checked, edges are generated for the output WEM.

Triangulate¶

name: triangulate, type: Bool, default: FALSE¶: If checked, non-triangle faces are being triangulated using the Triangulation Mode.

Triangulation Mode¶

name: triangulationMode, type: Enum, default: Center node¶: Defines the triangulation mode.

Values:

Title	Name	Description
Center node	Center node	A node is inserted to the center of the polygonal face and edges are added from this node to all the face’s original nodes.
Fan	Fan	From one node (the first one), edges are generated to all other nodes of the polygon.
Strip	Strip	Nodes on opposing sides are connected by edges.

Generate Primitive Value Lists¶

name: generatePrimitiveValueLists, type: Bool, default: FALSE¶: If checked, example values are set into the LUT PrimitiveValueList.
