Purpose

The WEMSceneLoader allows for loading triangle meshes as WEM patches using the Open Asset Import Library (assimp). The meshes are automatically triangulated if they contain quads or other non-triangle polygons.

Note: The STL format support of assimp is limited to loading only the first mesh in the STL file!

If you want to join identical vertices (Join Identical Vertices) that have different normals, you need to enable the Force Normal Generation and set Generate Normals to “SmoothNormals”.

It supports:

Visible Fields

Auto Apply

name: autoApply, type: Bool, default: TRUE

If checked, the module loads anew on every parameter change.

see also WEMGenerator.autoApply

Apply

name: apply, type: Trigger

When pressed, the module loads anew.

see also WEMGenerator.apply

Overwrite label and description

name: overwriteLabelDescription, type: Bool, default: FALSE

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

see also WEMGenerator.overwriteLabelDescription

Label

name: label, type: String

Sets a label string in the output WEM.

see also WEMGenerator.label

Description

name: description, type: String

Sets a description string in the output WEM.

see also WEMGenerator.description

Filename

name: filename, type: String

Sets the filename of the scene.

Log Detail

name: logDetail, type: Enum, default: Errors

Defines the detail of the logging.

Values:

Generate Normals

name: generateNormals, type: Enum, default: SmoothNormals

Defines how normals are generated when they are not present in the file.

Values:

Generate Edges

name: generateEdges, type: Bool, default: FALSE

If checked, edges are generated in the loaded WEM.

Normal Smoothing Crease Angle

name: normalSmoothingCreaseAngle, type: Float, default: 175

Sets an angle limit; if adjacent face normals have an angle greater than this limit, their shared nodes will be duplicated.

Join Identical Vertices

name: joinIdenticalVertices, type: Bool, default: TRUE

If checked, vertices that have identical position and properties are joined.

Find Degenerates

name: findDegenerates, type: Bool, default: TRUE

If checked, degenerate faces will be identified and removed.

Find Invalid Data

name: findInvalidData, type: Bool, default: TRUE

If checked, invalid data will be identified and a warning will be issued.

Optimize Meshes

name: optimizeMeshes, type: Bool, default: FALSE

If checked, the mesh will be optimized.

Force Normal Generation

name: forceNormalGeneration, type: Bool, default: FALSE

If checked, normal generation is forced even if the loaded file contains normals.
