This app provides an interactive environment to explore four and five dimensional data using some of MATLAB s abilities for volumetric visualization and animation. It was designed for data that was measured in a 3D grid of data points, for example temperature or wind speed taken at each point in a 3D space. If this data is taken over time, it can also be animated. Any data that fits the form v = f(x,y,z) or v = f(x,y,z,t) can be used.
