Purpose

The SoWEMConvertInventor module converts all triangles of an OpenInventor 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 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 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 searching and this is the index of the hash table.

Input Fields

The only input of the module is the OpenInventor 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: MLBase

self (hidden)

name: self (*hidden*), type: SoNode

Parameter Fields

Apply: Trigger	renderCulling: Enum
Auto apply: Bool
boundingBoxCaching: Enum
convertInfo: String
isProcessing: Bool
pickCulling: Enum
progress: Float

Visible Fields

Apply

name: apply, type: Trigger

If pressed, the module converts an input scene anew t0 a WEM.

Auto apply

name: autoApply, type: Bool, default: TRUE

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