Error in tsurf function about gptoolbox

[alecjacobson]

repmat('blue',size(V,1),1)

should be

repmat(blue,size(V,1),1)

[FeazAlkadi]

I did so, as following:

clf;
hold on;
t = tsurf(F,V,'EdgeColor','none',fsoft, 'FaceVertexCData',repmat(blue,size(V,1),1),'FaceAlpha',1+(iso<0)(0.35-1),fphong);
ts = tsurf(SF,SV,'EdgeAlpha',0.2+(iso<0)(0-0.2),fsoft,'FaceVertexCData',repmat(orange,size(SV,1),1),fphong,'FaceAlpha',1+(iso>0)(0.2-1));
apply_ambient_occlusion(ts);
hold off;
axis equal;
view(-20,20)
camlight;
t.SpecularStrength = 0.04;
l = light('Position',[5 -5 10],'Style','local');
add_shadow(t,l,'Color',0.8[1 1 1],'Fade','local','Ground',[0 0 -1 min([V(:,3);SV(:,3)])]);
set(gca,'pos',[0 0 1 1])
set(gca,'Visible','off');
set(gcf,'Color','w');
drawnow;

And now i got this error !

Attempt to execute SCRIPT ambient_occlusion as a function:
C:\Users\faa23\Desktop\3D_DiskTop\MatlabCodes\iges (original)\ambient_occlusion.m

Error in apply_ambient_occlusion/apply_ambient_occlusion_helper (line 79)

Do you have an idea what would be the problem ?

[FeazAlkadi]

SORRY, I posted the wrong error in the previous comment. I just updated that.

[alecjacobson]

have you changed ambient_occlusion.m? Do you have another file called ambient_occlusion.m in your path?

[FeazAlkadi]

No i didn't. And I don't have another file.
Does it need to be compiled too?
because I tried to compile it as oqilipo advised me to do for the function signed_distance as follow:

clearvars

path_to_eigen='C:\Users\faa23\Desktop\3D_DiskTop\MatlabCodes\iges (original)\eigen-eigen-';
% Check if the eigen path is correct
assert(exist([path_to_eigen '\Eigen\Core'],'file')==2)

path_to_libigl='C:\Users\faa23\Desktop\3D_DiskTop\MatlabCodes\iges (original)\libigl';

%%

MEXOPTS={'-v','-largeArrayDims','-DMEX'};

EIGEN_INC= ['-I' path_to_eigen];

LIBIGL_INC=['-I' path_to_libigl '\include'];
LIBIGL_FLAGS='-DIGL_SKIP';
LIBIGL_LIB={'-DIGL_SKIP'};
LIBIGL_LIBMATLAB='-DIGL_SKIP';
LIBIGL_LIBCGAL='-DIGL_SKIP';
LIBIGL_LIBCORK='-DIGL_NO_CORK';
LIBIGL_BASE={LIBIGL_INC, LIBIGL_FLAGS,LIBIGL_LIB{:}, LIBIGL_LIBMATLAB};

mex( ...
MEXOPTS{:}, ...
LIBIGL_BASE{:},EIGEN_INC, ...
'ambient_occlusion.cpp');

But there was a an error as follow:

Error using mex

The thing is that I did find any folder called embree2 in libigl !!!

[alecjacobson]

Sorry, I forgot that it's a Mex file. Yes, it needs to be compiled as you're trying. Looks like you're not including the path to the embree header files. Take a look in gptoolbox_mexopts. Not sure where your installation is or if it's different on W*ndows.

[FeazAlkadi]

Thank you so much Alec.
I hope someone can step up here :)

[FeazAlkadi]

Do you think think I should close this and open a new issue?
