Hello:
Is there a way to print a pdf without the white lines created by the anti aliasing issues in a surf plot. I realize that this can often be fixed in the pdf viewer, but I would like to address this issue so it doesn't occur to other viewers if these plots are published.
My code:
Center_0 = 50.7;
Center = 50.7;
NaN = 47.6;
X = [-3.5 -2.33, -1.167, 0, 1.167, 2.33, 3.5,...
-3.5, -2.33, -1.167, 0, 1.167, 2.33, 3.5,...
-3.5, -2.33, -1.167, 0, 1.167, 2.33, 3.5,...
-3.5, -2.33, -1.167, 0, 1.167, 2.33, 3.5,...
-3.5, -2.33, -1.167, 0, 1.167, 2.33, 3.5,...
-3.5, -2.33, -1.167, 0, 1.167, 2.33, 3.5,...
-3.5, -2.33, -1.167, 0, 1.167, 2.33, 3.5]/100;
Y = [ 3.5, 3.5, 3.5, 3.5, 3.5, 3.5, 3.5, ...
2.33, 2.33, 2.33, 2.33, 2.33,2.33,2.33,...
1.167, 1.167, 1.167, 1.167, 1.167,1.167,1.167,...
0, 0, 0, 0, 0, 0, 0,...
-1.167, -1.167, -1.167, -1.167, -1.167, -1.167, -1.167,...
-2.33, -2.33, -2.33, -2.33, -2.33, -2.33, -2.33,...
-3.5,-3.5,-3.5,-3.5,-3.5,-3.5,-3.5,]/100;
Z = [NaN,NaN,NaN,48.6,NaN,NaN,NaN,...
NaN, 48.5, 49.7, 49.8, 49.3, 48.0,NaN,...
NaN,49.7, 50.3, 50.4, 49.9, 48.7,NaN,...
48.1, 50.0, 50.5, 50.7, 50.1, 48.9, 47.6,...
NaN,49.7, 50.2, 50.3, 49.8, 48.6,NaN,...
NaN,48.2, 49.5, 49.7, 49.0, 48.0,NaN,...
NaN,NaN,NaN,48.5,NaN,NaN,NaN,]/Center;
X = reshape(X,7,7);
Y = reshape(Y,7,7);
Z = reshape(Z,7,7);
figure;
r = 3.5/100; % Radius of the sample [cm]
ang=0:0.01:2*pi;
xp=r*cos(ang);
yp=r*sin(ang);
zp = abs(5+xp);
h1 = surf(X,Y,Z, 'FaceColor','interp', 'EdgeColor', 'none');
xlabel('Radius [m]')
ylabel('Radius [m]')
colormap hot
view(2), colorbar, axis square tight
hold on
h2 = plot3(xp,yp,zp, 'w');
grid on
set(gca,'layer','top', 'tickdir', 'out', 'linewidth', 1.5);
tightfig_add_right;
print -dpdf -r600 In_Plane_0mm_HF_Map_080315.pdf
Thanks,
Josh

Use the opengl renderer. The last line to print the pdf should be:
print -dpdf -r600 -opengl In_Plane_0mm_HF_Map_080315.pdf

This sounds like the R2014b and later issue whose major discussion is at http://uk.mathworks.com/matlabcentral/answers/162257-problem-with-patch-graphics-in-2014b-splits-in-two-along-diagonal and which has not been resolved yet.
(I am seeing multiple posts from upset people saying that they are going to stop using MATLAB because of this; this and the problem with fonts not being included or being substituted as of R2014b eps files are generating a fair bit of bad feeling.)

No, I meant the part about not drawing the white circle with the opengl renderer. That sounds like a clip plane accuracy issue that I thought we had eradicated. If it's still around, I'd like to know how to repro it.
