Eigenvecdtor decomposre on Q failed!

marvin521 commented 6 years ago

Hi, thanks for the great work.

When I ran the script 'DemoFaceMapping.m', matlab gives me the errors:

Are you ready? Y/N [Y]: Y Started... eigenvector decomposer on Q failed! Q : nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan nan

xxx shape3D/get.TriHandle (line 76) out = triangulation(obj.Faces,obj.Vertices);% triangulation is a matlab construct that helps in a lot of computations

BTW, I am using OSX, and I have installed all the packages following the instructions except that my eigen version is 3.3.4

@alorcas can you take a look at this?

Dear marvin521,

Sorry for my late reply. We are still working on figure out this error and we hope to get back to you asap.

Kind regards

I come across the same issue as marvin521 met.

For the rigid registration section, I get warning message "eigenvector decomposer on Q failed!".

For the non-rigid registration section, I get the error message below:

Error using triangulation
The coordinates of the input points must be finite values; Inf and NaN are not permitted.

Error in shape3D/get.TriHandle (line 76)
            out = triangulation(obj.Faces,obj.Vertices);% triangulation is a matlab construct that helps in a lot

           out = single(obj.FloatingShape.VertexNormals);

Error in ShapeMapper/map (line 227)

Error in DemoFaceMapping (line 88)

Thank you for your effort.

@Patricklv the error is telling you what's wrong: 'The coordinates of the input points must be finite values; Inf and NaN are not permitted.'

So somewhere in the data you're inputting, you've got infinite or NaN values. That's why triangulation fails.

Dear @marvin521 and @Patricklv,

I have figured out that this error comes from the demoFace file that we have provided. I have updated it and you can find it in the Demo folder.

Best regards

@alorcas Hi! I am having the same problem and want to remove the NaNs from my 3D object files. Could you share how you went about doing that?

Thank you, Niraj
