The problem is that you
Hi,
The type signature is wrong. Try this..
toVertex :: GLVertex -> Vertex3 GLfloat
or perhaps..
toVertex :: (a,a,a) -> Vertex3 a

Yes this works (the first variant). Thanks ! But I must say that I have
problems to understand the class mechanism in its full extend
Greetings

Hi,
I have the following problem:
Vertex3 ist defined as
data Vertex3 a = Vertex3 a a a
a is defined as
class a VertexComponent
But I fail to write to following correct
type GLVertex = (GLfloat, GLfloat, GLfloat)
toVertex :: GLVertex -> Vertex3 a how do it correctly
toVertex (x,
