It is my understanding that you want to generate a similar shape by using “surf” plot as “fill3” plot does but i t is p ossible that the surface plotted by the surf function appears different from the surface plotted by fill3 because they use different algorithms to generate the surface. Pass the predefined colormap name, hot, to the colormap function. surf (ax, ___) plots into the axes specified by ax instead of the current axes. However, I need to update the position of this object over time. The XData, YData, and ZData properties on a Patch object created by the fill or fill3 functions return the coordinates using the original input data type, rather than returning. 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. If C is a 1-by-3 vector, it is assumed to be an RGB triplet, specifying a color directly. That eliminates the if test each pass at the cost of a little code upfront that duplicates that in the loop. * ORIGIN: 3-elements vector that defines the start point of the cube. fill3(X,Y,Z,C) fill3(X,Y,Z,ColorSpec) fill3(X1,Y1,Z1,C1,X2,Y2,Z2,C2,. example.

I am trying to create a filled 3d shape that will look similar to this: (long round object) (no need for the round part at the top, one color for all the object is good) I've tried to create many similar circles with different center point but it didn't work, and with. Although creating a pattern (i. 86] z = [0,-2. zlabel (ax, ___) adds the label to the axes specified by ax. "If X, Y, and Z are matrices of the same size, fill3 forms a vertex from the corresponding elements of X, Y, and Z (all from the same matrix location), and creates one polygon from the data in each column. 2) If the x,y point is inside the bottom perimeter of the region as (X,Y, Z=Z0), then test for min (Z) <= z <= max (Z), where Z. Patches can be specified using any of the input argument combinations in previous syntaxes. fimplicit3 (@ (x,y,z) abs (x)+abs (y)+abs (z)-1) You may also be interested in fplot, fplot3, fsurf, fmesh, fcontour, and fimplicit (some of these have been available since R2016a, but fimplicit3 was added in R2016b). 3. h2=fill3(X,Y,Z,[0 0 1]) note that the order of introduction of points matters, if you jump to an opposite vertex the square will look like a bow tie. % the origin (x, y, and z). 3. You can, though, use fill3 () with a constant Z location. When i press the button, through a button callback, i draw a 3d circle through this function, passing the handles. 4) This would create an x-y plane of blue colour. 0. To plot one region, specify X, Y, and Z as vectors. But now I need to adapt it to accept multiple other shapes (hexagon, pentagon, etc. Change the value of ‘N’ to get different numbers of sides (I experimented with a pentagon and hexagon successfully). fill3 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.
