9.11.1 Surf3 (Python)

Method on mglGraph (Python): void Surf3 (float val, mglData x, mglData y, mglData z, mglData a, const char *stl=NULL)

The function draws isosurface plot for 3d array specified parametrically a[i,j,k](x[i,j,k], y[i,j,k], z[i,j,k]) at a(x,y,z)=val. String sch sets the color scheme. Previous color scheme is used by default. If string contain ‘#’ then wire plot is produced. Arrays x, y, z can be vectors (not 3d arrays as a). Note, that there is possibility of incorrect plotting due to uncertainty of cross-section defining if there are two or more isosurface intersections inside one cell. See also Cloud, Dens3, Surf3C, Surf3A, Axial. See section Surf3 sample, for sample code and picture.

Method on mglGraph (Python): void Surf3 (float val, mglData a, const char *sch=NULL)

The same as previous with x, y, z equidistantly distributed in interval [Min, Max].

Method on mglGraph (Python): void Surf3 (mglData x, mglData y, mglData z, mglData a, const char *stl=NULL, int num=3)

Draws num-th uniformly distributed in range [Cmin, Cmax] isosurfaces for 3d data specified parametrically.
