Currently only ".stl" files can be exported in Iris Web Viewer. There are some things to be aware of how the files are exported as well.
STL files are often used for 3D printing which makes them very common and are a useful file extension. Iris can export ASCII stl files which are then saved to the users download folder.
- STL files only specify one normal per face, therefore the exported Normal for each face is the average of all three vertices. This means that if each vertice of a given face has a different normal, the result in the export file will be averaged and shared among each vertex.
