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,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
