Abstract

We propose a robust re-meshing approach that can automatically generate visual-preserving low-poly meshes for any high-poly models found in the wild. Our method can be seamlessly integrated into current mesh-based 3D asset production pipelines. Given an input high-poly, our method proceeds in two stages: 1) Robustly extracting an offset surface mesh that is feature-preserving, and guaranteed to be watertight, manifold, and self-intersection free; 2) Progressively simplifying and flowing the offset mesh to bring it close to the input. The simplicity and the visual-preservation of the generated low-poly is controlled by a user-required target screen size of the input: decreasing the screen size reduces the element count of the low-poly but enlarges its visual difference from the input. We have evaluated our method on a subset of the Thingi10K dataset that contains models created by practitioners in different domains, with varying topological and geometriccomplexities. Compared to state-of-the-art approaches and widely used software, our method demonstrates its superiority in terms of the element count, visual preservation, geometry, and topology guarantees of the generated low-polys.

News

Our surface remeshing exe is released! Check here for details.

Run Exe

To execute our executable file, follow these steps:

./SurfaceRemeshingCli_bin.exe -i "YourObjMeshFile.obj" -n 100

Here’s what each option means:

The -i flag specifies the input mesh file in .obj format.
The -n flag allows you to adjust precision. A higher number yields a more precise result but consumes more time and memory. Please note that the current version supports a maximum precision level of -n 400.

For more detailed information about available parameters, you can run:

./SurfaceRemeshingCli_bin.exe -h

This command will provide you with comprehensive details on the available options and their usage.
