An exemplary method for tessellating a primitive of a graphical object includes receiving information for a primitive of a graphical object where the information includes vertex information and an edge factor for each edge of the primitive; based on the received information, dividing the primitive into parts where each part corresponds to at least a portion of an edge of the primitive and at least one vertex of the primitive and where each part has an association with the edge factor of the corresponding edge; for each of the parts, executing a geometry shader on a graphics processing unit (GPU) where the executing includes determining barycentric coordinates for a respective part based in part on its associated edge factor; for each of the parts, outputting the barycentric coordinates to a vertex buffer; and generating a tessellated mesh for the primitive based on the vertex information and the barycentric coordinates of the vertex buffer where the generating includes invoking a draw function of the GPU. Other methods, devices and systems are also disclosed.
