Matlab surface isolines

Hi, I have a triangular surface that I'm plotting using the trimesh() function. Each node of my mesh has a value that I am representing using the figure colorscale. What I would like to do is add "isolines" to the surface so you can get a better since of the data. However, when I try using plot3() to plot these lines on top of the surface, most of them are not visible. Does anyone know how I can plot visible lines on top of a surface in matlab?

EDIT per comments:
Of course; set the facealpha property of the mesh to a small number (1 is opaque, 0 is transparent). This will allow your line to be visible:
[x,y]=meshgrid(1:15,1:15); %ml example from doc
tri = delaunay(x,y);
z = peaks(15);
trimesh(tri,x,y,z,'facealpha',0.2)
hold on
plot3([1 30],[1 30],[0 pi])
