plot3d3 - mesh plot surface defined by rectangular facets
Note that the surface color treatement can be done using color_mode and color_flag options through the surface entity properties (see surface_properties ).
Note that axes boundaries can be customized through the axes entity properties (see axes_properties ).
Note that axes aspect can also be customized through the axes entity properties (see axes_properties ).
plot3d3 performs a mesh plot of a surface defined by rectangular facets. (X,Y,Z) are three matrices which describe a surface. The surface is composed of four sided polygons.
The X-coordinates of a facet are given by X(i,j),X(i+1,j),X(i,j+1),X(i+1,j+1). And similarly Y and Z are Y and Z coordinates.
The vect vector is used when multiple surfaces are coded in the same (X,Y,Z) matrices. vect(j) gives the line at which the coding of the jth surface begins. See plot3d2 for a full description. As a mesh plot, the only available property you can edit is the visible option (see axes_properties ).
u = linspace(-%pi/2,%pi/2,40); v = linspace(0,2*%pi,20); X = cos(u)'*cos(v); Y = cos(u)'*sin(v); Z = sin(u)'*ones(v); plot3d3(X,Y,Z); // New Graphic mode only e=gce(); // get the current entity e.visible='off'; e.visible='on'; // back to the mesh view
