Yes this works (the first variant). Thanks ! But I must say that I have problems to understand
The problem is that you tried to tell the compiler that toVertex would return a parametrised type, namely 'Vertex3 a', but that the compiler sees that toVertex, when given a 'GLVertex' always will produce 'Vertex3 GLfloat'.
the class mechanism in its full extend....
Classes doesn't have anything to do with this. -kzm -- If I haven't seen further, it is by standing in the footprints of giants
