<p>Abstract METHOD, APPARATUS AND SYSTSEM FOR TESSELLATING A PARAMETRIC A method of tessellating a parametric patch (610) of an object is disclosed. A boundary 5 curve associated with the parametric patch (610) is vectorised according to a pre-determined flatness tolerance. A tessellation point associated with a first parametric value inside the parametric patch (610) is determined based on geometry of the parametric patch (610) and a tessellation step. A curve associated with the first parametric value is determined based on the geometry of the parametric patch (610) and the tessellation step. A colour split point on the 10 vectorised boundary curve is determined. The colour split point is determined based on the vectorised boundary curve and the determined curve associated with the first parametric value. The parametric patch (610) is tessellated by joining the colour split point and the tessellation point.
