The X, Y, Z, C parameters can be followed by parameter/value pairs to specify additional properties of the patches. A number of MATLAB ® functions create patch objects — fill, fill3, isosurface, isocaps, some of the contour functions, and patch. In this syntax, a hole is defined as an area of dark pixels surrounded by lighter pixels. CData; p. 0. By changing property values, you can modify certain aspects of the patch. When attempting to change parameters like transparency and face colour, it can get confusing, so let's simplify. Specify a color name or a short name from the table below, or specify one RGB triplet. e. More specifically, we are going to draw several flat surfaces (planes) to build or model a box. 1 Answer. If you'll do it for an hellicopter, you will see a disk like shape from above (the aerea between. By doing so, MATLAB is now trying to use your file when you call fill3 . I have a matrix for contact positions and these positions are linear, therefore I can easily plot the contact positions within MATLAB and come out with the x amount of lines.

TR = stlread (filename) returns a triangulation object TR containing the triangles defined in an STL file. 2. Well, I did mention how to do that, but only briefly. So, I compared my plot (using fill3) to the similar plot with surf with the get() function and noticed that my cdata is empty and my zdata is only retained for the most recent data points. fill3 (X,Y,Z,C) plots filled polygonal regions on 3-D axes as Patch objects with vertices at the ( x, y, z) locations specified by X, Y, and Z. Reissuing the ylabel command causes the new label to replace the old label. The two surf calls (one for each cylinder) draws the cylinders. The short names and long names are MATLAB strings that specify one of eight predefined colors. fill3 sets the patch object FaceColor property to flat, interp, or a ColorSpec depending upon the value of the C matrix.
