Hi,

i try to set Color to every Triangle explicitily. (Code at the end)
Without setColor it works fine an i see two Triangles in the canvas3D.
But if i try to set the Colors i got following error ..

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException:
GeometryArray: has no colors
    at javax.media.j3d.GeometryArray.setColor(GeometryArray.java:1279)
    at ipbmesh.SimpleMeshViewer.insertMesh(SimpleMeshViewer.java:218)
    at ipbmesh.SimpleMeshViewer.createSceneGraph(SimpleMeshViewer.java:155)

How i can solve this problem, that IndexedTriangleArray instanciate a
ColorTable ?

Thanks for Help

Richard
