Is it possible to export a MeshVS_Mesh to STL

Timo Roth's picture
Forums: 

For importing STL files, we use the code mentioned at the end of http://www.opencascade.org/org/forum/thread_9793/?forum=3 .

It creates a MeshVS_Mesh from the STL file.
MeshVS_Mesh is a subclass of AIS_InteractiveObject and therefore can be transformed via its SetTransformation method.

Is it possible to export such a transformed MeshVS_Mesh to STL?

RWStl::WriteAscii (const Handle &aMesh, const OSD_Path &aPath );
can be used to write StlMesh_Mesh objects.
Is it possible to get an StlMesh_Mesh from a MeshVS_Mesh?

Regards

To my knowledge OpenCascade doesn't have a direct facility to do this.

The gmio C library provides a tool to export a MeshVS_DataSource to STL(see doc).
Just transform each facet before actual writting, for that redefine gmio_stl_mesh::func_get_triangle().

Greetings.
