3.12.4 Surf3A

Method on mglGraph (C++, Python): void Surf3A (float val, const mglData &x, const mglData &y, const mglData &z, const mglData &a, const mglData &c, const char *stl="")

C function: void mgl_surf3a_xyz_val (HMGL gr, float val, const HMDT x, const HMDT y, const HMDT z, const HMDT a, const HMDT c, const char *stl)

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. It is mostly the same as Surf3() function but the transparency of isosurface depends on values of b array. This allows one to remove the part of isosurface where b is negligibly small (useful for phase plotting of a beam or a pulse). String sch sets the color scheme. Previous color scheme is used by default. If string contain ‘#’ then wire plot is produced. All dimensions of arrays z and c must be equal. 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 Surf3, SurfA, Surf3C. See section Surf3A sample, for sample code and picture.
