In the 3-D visualization methods discussed so far, we have been concerned with surfaces. Volume visualization is concerned with representing a threedimensional matrix of points, i.e., a volume, in which each point can be either a scalar (magnitude only) or vector (magnitude and direction). Scalar data is a single value for each point, while vector […]
Stream Plots Since vector volume data can be thought of as particles flowing through a volume, it is desirable to have some visualization methods that indicate the direction of flow. Stream plots do just that. The differences amongst the stream plots provided in MATLAB have to do with the way the streams are visualized. Stream […]
