The refine/hypothesis buttons are gray #4

Closed waysup closed 7 years ago

waysup commented 7 years ago

Hi Liangliang, Thank you for your great project. I got into trouble while runing PolyFit.exe. All four buttons are gray as shown in the snapshot( FYI, I'm runging your prebuilt PolyFit.exe on Windows 7 64-bit). default is this due to the lack of GUROBI license( I don't have one yet)? Or I have to install GUROBI on my machine? Thx.

Hi Waysup,

Thank you for your email. Could you please provide more information regarding this issue, i.e., how to reproduce it, or after what operation does it occur?

GUROBI is used for solving the optimization in PolyFit, so you do need to obtain a license (it is free for academic use): http://www.gurobi.com/registration/academic-license-reg

Let me know if you still have the same or other problems using PolyFit.

Best,

Liangliang

Hi Liangliang, Thanks for your quick reply. These four buttons(refine/hypothesis/confidences/optimization) remain gray/unactive(as shown in previous snapshot) after I loaded my obj file into PolyFit. So I can do nothing after loading my model in PolyFit, though it renders the model correctly. Here is the snapshot. image I wonder why these four buttons are gray. Cheers.

Now I know the reason :-) PolyFit takes as input a point cloud with planar segment information (file format must be .vg or .bvg). The model you sent to PolyFit is a mesh and PolyFit is not designed to process meshes. Please have a look at ReadMe-data.txt in the PolyFit_data folder.

Best,

Liangliang
