The surfl function creates a surface plot with colormapbased lighting. Colormaps are threecolumn arrays containing rgb triplets in which each row defines a distinct color. In principle it is possible to insert text in the u3d file, but it is much more difficult than in a prc file. Additionally, x can be a row or a column vector, and y a matrix with lengthx rows. The media9 latex package can import u3d files with their associated vws files in a pdf document. This example shows how to create an animation of two growing lines. One type of 3d plot that may be useful is a surface plot, which requires you to generate some kind of xy plane and then apply a 3rd function as the z dimension.
The correspondence between the colors and your data values depends on the type of visualization you create. For example, use a histogram to group data into bins and display the number of elements in each bin. From the plot catalog tool, select the 3d surfaces in the categories column. Increasing meshdensity can make smoother, more accurate plots, while decreasing it can increase plotting speed. If s is a row or column vector, then each entry in s specifies the area for the corresponding marker. What method would you recommend for exporting matlab 3d. The column and row indices of z are the x and y coordinates in the plane, respectively. When y is a matrix, ribbon plots each column in y as a ribbon at the corresponding x location. Whether its for research, a school assignment, or a work presentation, 3d plots are great for visualizing what a complicated set of data looks like.
Volume visualization is the creation of graphical representations of data sets that are defined on threedimensional grids. For example, you can compare sets of data, track changes in data over time, or show data distribution. Customize plots either interactively or programmatically.
