In addition,you can also use the GRIDSTYLE, LIGHTMODEL, and AMBIENTLIGHToptions.For details on the various options to the PLOT3D structure, see the?plot3d,structure help page.6.4 Programming with Plot Data StructuresThis section describes tools for programming at the PLOT and PLOT3Ddata structure level. Plotting data structures allows direct access to theMaple plotting facility. The examples in section 6.3 show the extent ofthe facilities’ power. In this section, you learn how to thicken the lines in
