A method of rendering a parametric patch. The patch is defined by a geometry and a color varying according to a surface mapping points of the patch to intermediate values. Each of the intermediate values is mapped to a color value according to a shading color function. A set of intermediate values is determined for the patch. The determined set of intermediate values represent an approximation of the shading color function by linear segments. The patch is tessellated into a plurality of cells. Tessellation points are determined for each of the plurality of cells according to the determined set of intermediate values. A further cell is formed for the patch by joining, within each of said plurality of cells, a plurality of the tessellation points being of equal intermediate value and approximating isolines of the surface. The patch is rendered using the intermediate values.
