[SOLVED] CGALplugin(MeshGenerationFromImage):Error in creating file data/output.vtu

[Lujain]

Hi guys,
When I tried to use CGALplugin to generate mesh as described in . I tested the runSofa applications/plugins/CGALPlugin/scenes/MeshGenerationFromImage.scn. It can generate mesh but fialed to export. As follows:

I didn’t solve this problem. It will be very kind of you to give me some advice.

Hi,
I modified the MeshGenerationFromImage.scn in the line:

<VTKExporter name=”exporter” filename=”data/output.vtu”  XMLformat=”1″ edges=”0″ tetras=”1″  listening=”true” exportAtBegin=”true” cellsDataFields=”generator.outputCellData” overwrite=”true”/>

by changing the filename=”output”. Now it can export the vtu file and can be shown in Paraview.

Thank you for the feedback Lujain !
Good work ! Keep us updated
