Purpose

The SoWEMConvertInventor module converts all triangles of an Open Inventor scene into the WEM format (winged-edge mesh). The complexity of the algorithm to convert all triangles is O(n(logn)), with n = number of vertices.

Usage

Connect the Open Inventor scene to be converted to this module and press Apply.

Details

The module uses a hash table to test if a vertex of a new incoming triangle has been already processed and is already a WEM node in the WEM data structure. The bounding box of the scene is divided in NxNxN cubes (currently N=10, because of memory capacity). For each vertex, the corresponding cube is searched to result in the index of the hash table.

Input Fields

The only input of the module is the Open Inventor scene to be converted.

inScene

name: inScene, type: SoNode

Output Fields

The module has the converted scene as a WEM output. The SoNode output is not used and is hidden.

outWEM

name: outWEM, type: WEM(MLBase)

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

self (hidden)

name: self, type: SoNode

Parameter Fields

Field Index

Apply: Trigger	renderCulling: Enum
Auto apply: Bool	Use Node Colors: Bool
boundingBoxCaching: Enum
convertInfo: String
isProcessing: Bool

Visible Fields

Apply

name: apply, type: Trigger

When pressed, the module converts an input scene anew to a WEM.

Auto apply

name: autoApply, type: Bool, default: TRUE

If checked, the module converts the input WEM to a Open Inventor scene on each change of the input WEM.

Use Node Colors

name: useNodeColors, type: Bool, default: FALSE

If checked, the diffuse colors of the Open Inventor scene are set as WEM node colors.
