How to plot 3d patch with Faces and vertices

49 views (last 30 days)
I found the patch function, which allows me to plot patches given faces and vertices. As I am working with 3d data, my faces data is a 10670x3 matrix and the vertices are a 6136 x 3 matrix. When I try to display them with
patch('Faces', faces, 'Vertices', vertices)
It just plots the data projected to a 2d plane. How can I plot them in 3d?

Try this:
patch('faces',faces,'vertices',vertices(:,1:2),'facevertexcdata',vertices(:,3),'facecolor','interp','edgecolor','none') ;
colorbar

it does add color to display the 3d part, but I was looking for a 3d graph, where the poinst are plotted in 3d space

There is edgecolor option....you change it to black or someother color. HAve a look on triplot, trimesh.

trimesh(faces, vertices(:,1),vertices(:,2),vertices(:,3))
solved it for me. Thanks KSSV
