surfaceMeshImport
|
||||
|
||||
Description
|
||||
Import from various third-party surface formats into surfMesh
|
||||
with optional scaling or transformations (rotate/translate)
|
||||
on a coordinateSystem.
|
||||
|
||||
Usage
|
||||
- surfaceMeshImport inputFile [OPTION]
|
||||
|
||||
@param -clean \n
|
||||
Perform some surface checking/cleanup on the input surface.
|
||||
|
||||
@param -name \<name\> \n
|
||||
Specify an alternative surface name when writing.
|
||||
|
||||
@param -scaleIn \<scale\> \n
|
||||
Specify a scaling factor when reading files.
|
||||
|
||||
@param -scaleOut \<scale\> \n
|
||||
Specify a scaling factor when writing files.
|
||||
|
||||
@param -dict \<dictionary\> \n
|
||||
Specify an alternative dictionary for constant/coordinateSystems.
|
||||
|
||||
@param -from \<coordinateSystem\> \n
|
||||
Specify a coordinate System when reading files.
|
||||
|
||||
@param -to \<coordinateSystem\> \n
|
||||
Specify a coordinate System when writing files.
|
||||
|
||||
Note
|
||||
The filename extensions are used to determine the file format type.
