Aug 29, 2021 · plot3(y(:,1),y(:,2),0*y(:,3), 'color', 'k','LineWidth',1); % shadow on the X-Y plane which produces a graph like this: FYI, you can also use imagesc to produce shadow for a surface like the example in this page which basically adds a 2D image of a 3D surface on the axes.

Aug 4, 2014 · You can simply plot the shadow points using plot3 and making one of the axes as zeroes.

Mar 11, 2025 · You can download the Shadows for MATLAB project from github or File Exchange to get all the code for this blog in handy utility functions, plus a repository of STL files you can print for different stereographically projected shapes.

Nov 13, 2024 · For some surface plots, it can be helpful to visualize the shadow (2D projection) of the surface. This can give a quick perspective on the data's variance. HS = SHADOWPLOT (...) Returns a handle to the shadow (a patch) Michelle Hirsch (2025). SHADOWPLOT (https://github.com/michellehirsch/MATLAB-Shadowplot), GitHub. Recuperado 14 febrero, 2025.

SHADOWPLOT Add a shadow to an existing surface plot. For some surface plots, it can be helpful to visualize the shadow (2D projection) of the surface. This can give a quick perspective on the data's variance.

Jan 5, 2024 · Use ‘view (90,0)’ for the ‘x-z’ view, and ‘view (0,0)’ for the ‘y-z’ view. Use the print function with '-dpng' to save each of them as a separate image if that is what you want to do. The final version with a few edits is as follows. I did the derivation process as follows. If you have a different suggestion, I can take it. As always, my pleasure!

Jan 26, 2018 · I have a set of X,Y,Z data where X and Y represent coordinates and Z the corresponding elevation. How can I now plot a 2D image with the projection of the 3D surface on it?

Nov 22, 2011 · I have a function f(x,y)= Exp(-x^2-y^-2)(x^2+y^2). I would like to look at the projection of this function onto the x-axis in MATLAB. Any thoughts on the best way to do this?

Mar 3, 2025 · Today I'd like to explore a simple way to compute and draw shadows on the floor of your axes. Let's start by creating a shape that will cast a shadow. I'll go with a donut shaped ribbon similar to the photo above, but to make it more interesting, I'll oscillate the perimeter.

Apr 28, 2021 · To create a 2D projection of a 3D plot defined by a function (f (x, y, z)) in MATLAB, use the contourf function, which provides a filled contour plot, making the 2D representation clearer.
