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,y,z) = Vertex3 x y z
The compiler says "cannot infer a with type GLFloat" or something like this.... I don't understand.
Thank you for help
Hans
