Syntax
vis3d(scalar3d, x_intercepts, y_intercepts, z_intercepts, [opts]) vis3d(scalar3d, x_intercepts, y_intercepts, z_intercepts, obj_array, [opts]) vis3d(scalar3d, x_intercepts, y_intercepts, z_intercepts, obj_array, src_array, [opts]) vis3d(scalar3d, [opts]) vis3d(scalar3d, obj_array, [opts]) vis3d(scalar3d, obj_array, src_array, [opts])
Description
vis3d(scalar3d, x_intercepts, y_intercepts, z_intercepts) vizualizes x-, y-, z-normal slices of a 3D array of data stored in an instance of Scalar3d. x_intercepts, y_intercepts, z_intercepts are arrays of real numbers indicating the x-, y-, z-intercepts of the slices. Any of the three arrays of intercepts can be empty arrays ([]) to show no slices normal to the corresponding directions. Any of the three arrays of intercepts can be NaN to show slices normal to the corresponding directions at default locations.
vis3d(scalar3d) is equivalent to vis3d(scalar3d, NaN, NaN, NaN), and it vizualizes x-, y-, z-normal slices at default locations. The default locations are automatically set at the most prominent locations.
vis3d(..., obj_array) visualizes the objects in obj_array with the slices. The elements of obj_array are instances of Object.
vis3d(..., obj_array, src_array) visualizes the objects and sources in obj_array and src_array with the slices. The elements of src_array are instances of Source.
The optional argument opts is an options structure that controls the behavior of visualization. The fields of the structure are explained below. The default values of the fields are shown in brackets {}.
- opts.withgrid: true or {false} to show the grid or not.
- opts.withinterp: {true} or false to interpolate the field or not.
- opts.withpml: true or {false} to show the PML regions or not.
- opts.withabs: true or {false} to show the absolute values of the field or not.
- opts.cscale: positive value that controls the color bar range. Set to values less than 1.0 to saturate colors. The default value is 1.0.
- opts.cmax: another positive value that controls the color bar range; the positive maximum of the color bar range is cscale * cmax. If it is set to NaN, which is the default, then cscale * (maximum amplitude of the plotted data) is used for the maximum of the color bar range.
- opts.withcolorbar: {true} or false to show the colorbar or not.
- opts.withobjsrc: true or false to show the objects and sources or not. The default values is true when the number of objects is small (20), but false when the number of objects is large ( 20). To show only sources without objects, provide an empty obj_array in vis3d().
- opts.phase: additional phase angle phi. The field is visualized with an additional factor exp(i*phi) multiplied. Not useful if opts.withabs = true.
Example
[E, H, obj_array, src_array] = maxwell_run({ARGUMENTS});
opts.cscale = 5e-3;
opts.wihabs = true;
vis3d(E{Axis.y}, 0, [], 0, obj_array, src_array, opts);
