Module GluTess

module GluTess: sig .. end
type winding_rule = [ `abs_geq_two | `negative | `nonzero | `odd | `positive ] 
type vertices = (float * float * float) list 
val tesselate : ?winding:winding_rule ->
       ?boundary_only:bool -> ?tolerance:float -> vertices list -> unit

Render directly to current screen. Each vertices in the input is a contour in the single polygon represented by vertices list.

type triangles = {
   singles : vertices list;
   strips : vertices list;
   fans : vertices list;
} 
val tesselate_and_return : ?winding:winding_rule ->
       ?tolerance:float -> vertices list -> triangles

Return 3 lists of triangles instead of rendering directly
