Sorry, I meant a triangle which consists only of TWO points, not three
;-)


Yet how can GeometryArray load the same data.
I set the triangle myself so I am pretty sure that they are multiples of
three.

But by the way, why don't you use a Cylinder for this kind of "rounded
stick"?

Ends match nicely

I have some code that generates a 'rounded stick' like object I use for

and
looks like it could save me a lot of work. That is if I could get it to
work.
Case 1:

def createNormals(self):
 gi = GeometryInfo(GeometryInfo.TRIANGLE_ARRAY| LineArray.COLOR_3)
 gi.setCoordinates(self.verts)
 nm = NormalGenerator()
 nm.generateNormals(gi)
 si = Stripifier()
 si.stripify(gi)
 return gi.getGeometryArray(1,0,0)
Result:

java.lang.IllegalArgumentException: StripCounts inconsistent with
primitive
at com.sun.j3d.utils.geometry.GeometryInfo.checkForBadData
Yet it works if I create a GeometryArray.TRIANGLE_ARRAY with the same
data
it works.
Huh ?

Thanks for any help?
