Marching Windows: Scalable Mesh Generation for Volumetric Data with Multiple Materials

This repository contains code for the paper: Marching Windows: Scalable Mesh Generation for Volumetric Data with Multiple Materials

inal volumetric data. In this paper we propose a novel approach, called Marching Windows, that uses a moving window and a disk-swap strategy to reduce the run-time memory footprint, devise a new scheme that guarantees to preserve the topological structure of the original dataset, and adopt an error-guided optimization technique to improve both geometric approximation error.

Set Up Environment

Below are the main packages we used in thie project:

• boost 1.56.0
• CGAL
• hdf5 1.10.1
• opencv 2.4.9
• SparseSky
• tetgen
• zlib

Repository Structure

Below are the main directories in the repository:

• console/: the code call the main functions of simlification;
• simplification3d/: the main code for the simplification functions.
• data/: the code to prepare the datasets from labeled data

Running the Code

Dataset preparation

• Download the image files
• Run png2svdata python scripts to process the data

Usage and Options

Compile the code (with preferably VS2012), run the compiled project with command as:

.\simplification3d [data_folder] [target_simplifying ratio_usually_0.01] [odt_count] [target_edge_variance] [dim_x] [dim_y] [dim_z]

Results

Results of different datasets.
