This example shows several methods for visualizing volume data in MATLAB®.
Volume visualization is the creation of graphical representations of data sets that are defined on three-dimensional grids.
There are several techniques available for visualizing scalar volume data, such as MRI slices.
This example shows several techniques to visualize four dimensional (4-D) data in MATLAB®.
There are several techniques that are useful for visualizing vector data, such as stream lines, stream particles, stream ribbons, stream tubes, and cone plots.
A slice plane is a surface that takes on coloring based on the values of the volume data in the region where the slice is positioned.
Isosurfaces are constructed by creating a surface within the volume that has the same value at each vertex. Isosurface plots are similar to contour plots in that they both indicate where values are equal.
Isocaps are planes that are fitted to the limits of an isosurface to provide a visual context for the isosurface.
Visualize air currents in 3-D using streamlines, slice planes, and contours on the same plot.
Stream ribbons illustrate direction of flow, similar to stream lines, but can also show rotation about the flow axis by twisting the ribbon-shaped flow line.
Stream tubes are similar to stream lines, except the tubes have width, providing another dimension that you can use to represent information.
Visualize the speed and direction of particles within vector fields using streamlines.
This example shows how to use cone plots, isosurfaces, lighting, and camera placement to visualize a vector field.
