SoSceneLoader¶

InventorModule
¶ author MeVis Medical Solutions AG
package MeVisLab/Standard
dll SoLoaders
definition SoLoaders.def
Purpose¶
The SoSceneLoader
allows for loading meshes as Open Inventor points, lines, triangles, and faces using the
Open Asset Import Library.
Note: The STL format support of assimp is limited to loading 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 turn Generate Normals
to “SmoothNormals”.
It supports:

Tips¶
The module supports materials and it is possible to insert a material shader to each material using the inMaterialShader
.

Visible Fields¶
Update Mode¶
-
name:
updateMode
, type:
Enum
, default:
AutoUpdate
¶ Defines the output update mode.
Values:
Title | Name | Description |
---|---|---|
Auto Clear | AutoClear | Automatically clear the output scene if parameters change. Requires manual loading of scene. |
Auto Update | AutoUpdate | Automatically reload scene if parameters change. |
Off | Off | No automatic updates. Loading and clearing must be done explicitly. |
Calculate Tangents¶
-
name:
calculateTangents
, type:
Bool
, default:
FALSE
¶ If checked, the module calculates tangents (for normal mapping) and adds them as the vertex attribute oiv_Tangents.
Join Identical Vertices¶
-
name:
joinIdenticalVertices
, type:
Bool
, default:
TRUE
¶ If checked, the joining of vertices with the same attributes is enabled.
Remove Redundant Materials¶
-
name:
removeRedundantMaterials
, type:
Bool
, default:
TRUE
¶ If checked, unused or duplicate materials are removed.
Find Degenerates¶
-
name:
findDegenerates
, type:
Bool
, default:
TRUE
¶ If checked, degenerated faces are searched for and removed.
Find Invalid Data¶
-
name:
findInvalidData
, type:
Bool
, default:
TRUE
¶ If checked, invalid data is searched for and warned about.
Split Large Meshes¶
-
name:
splitLargeMeshes
, type:
Bool
, default:
FALSE
¶ If checked, large meshes are split into smaller ones.
Improve Cache Locality¶
-
name:
improveCacheLocality
, type:
Bool
, default:
FALSE
¶ If checked, the cache locality is improved by reordering vertices/faces.
Optimize Meshes¶
-
name:
optimizeMeshes
, type:
Bool
, default:
FALSE
¶ If checked, the meshes are optimized for rendering.
Force Normal Generation¶
-
name:
forceNormalGeneration
, type:
Bool
, default:
FALSE
¶ If checked, normal generation is forced, even if the loaded model contains normals.
Log Detail¶
-
name:
logDetail
, type:
Enum
, default:
Errors
¶ Defines the detail of the log output.
Values:
Title | Name |
---|---|
Errors | Errors |
Warnings | Warnings |
Verbose | Verbose |
Debugging | Debugging |
