I know matlab has patch function, which is patch(X,Y,Z,C) creates a patch in 3-D coordinates. If the coordinate data does not define closed polygons, patch closes the polygons. The data can define concave or intersecting polygons. However, if the edges of an individual patch face intersect themselves, the resulting face might be only partly filled. In that case, it is better to divide the face into smaller polygons.
I can use it to plot my figure normally, but the question is I need to do this work in the background (something like use patch to plot the figure(no display), then save the figure as jpg or eps in the background, then only display the jpg or eps.)
can anyone help me? Thanks,
LZ

I ran the code with XX, YY, ZZ, and C each set to different rand(1,53), and had no problems in 2008b on Linux-64.

yes, in normal, this code is fine, and has no problem,
but I run this code in unix "background",and it come out these errors.

Undefined function or variable sphere_tri
The missing mask.mat and ack1.mat are also going to cause problems for other people wishing to debug your code.

I tried switching to
set(h,'Renderer','painters')
in my sample code. It is taking a long time to execute; hard to say yet ha terminate.
Liang Zhan

let me test in my side.
where should I add set(h,'Renderer','painters')?
just before
saveas(h,'figure_test_no_display.jpg')?
thanks,
