Usage

Input & Output

We support .off and .obj for input and the output is .obj. There will be three output meshes for each input model.

• _vd.obj -- the result mesh after visual driven processing
• _opt.obj -- the result manifold mesh after gloabl topology optimization
• _opt_HR.obj -- the more concise manifold mesh with hidden patch removal

Call the Program

MeshViewer.exe PATH_TO_INPUT_FILE Eps_Visual Csl_min W1 W2 Num_threads

• PATH_TO_INPUT_FILE - the path to a triangle mesh in .off or .obj
• Eps_Visual and Csl_min - parameters that control the visual driven processing step
• W1 and W2 - the weights of E_ori and E_reg in the manifold mesh reconstruction step
• Num_threads - controls the number of cpu threads used

Suggested default parameter values are given in the following example and discussed in the paper/supplemental document.

Test Examples

For example: MeshViewer.exe .\PATH_TO_Test_examples\airplane_0627.off 0.0056 0.08 5 1 8

Processed Datasets

We provide 10k processed meshes of ModelNet and ShapeNet by our program. The meshes are named according to their sources in the respective datasets.
