Hi,
does the Qt3D GeometryRenderer class support TriangleStrip
primitives with restartIndexValue separated Strips?
Yes. Set the primitiveType property to LineStrip and you can specify
the restart index value with
https://doc.qt.io/qt-5/qt3drender-qgeometryrenderer.html#restartIndexValue-prop.
Cheers,

Thanks, Shawn.
Rereading my question, I think I need to clarify what I'm after.
Is it possible for a single GeometryRenderer with primitiveType
`TriangleStrip` to contain multiple indexed TriangleStrips where the
indexArray entries of the strips are separated by a
`restartIndexValue`? When testing this, I saw some rendering artifacts
with Qt 5.10.0.
Apparently (according to my tests) a GeometryRenderer with
primitiveType ' Triangles' does support this, but is it supported for
primitiveType `TriangleStrip` too?
It should work, yes. If you have a test case where this doesn't work as
expected, please file a bug report in jira with the test case.
Cheers,
Sean
