QMVC - Quad Mean Value Coordinates

Overview

Reference implementation of the research paper: Mean value coordinates for quad cages in 3D, Jean-Marc Thiery, Pooran Memari and Tamy Boubekeur, ACM Transactions on Graphics - Proc. SIGGRAPH Asia 2018

This repository contains:

QMVC/coordinates, a set (header-only) methods to compute popular space coordinates, including
- Green Coordinates (GC),
- Mean Value Coordinates (MVC),
- Spherical Mean Value Coordinates (SMVC),
- maximum Entropy coordinates (MEC),
- our Quad Mean Value Coordinates (QMVC),
QMVC/viewer, an interactive 3D viewer allowing to
- compute the projection of a mesh within the space coordinates of a cage
- deform the the mesh using the cage
QMVC/data, a data set of 3D models (OBJ format) with, for each model
- the high-poly input mesh
- a coarse binding cage
- a deformation of this cage.

Release Notes

v1.0

Dry push of the paper's reference implementation. Future releases will be cleaner and easier to deploy.

Building

Viewer's dependencies:

Qt5.5.1 or more recent
libQGLViewer-2.6.1 or more recent
GNU GSL
GLEW 2.0 or more recent

Adapt the content of the file viewer/QMVCViewer.pro to your setting e.g., path to libGLViewer

This application has been tested successfully on Linux Ubuntu and MS Windows 10.

To compile it on Linux:

$ cd <path-to-QMVC>/viewer
$ qmake 
$ make

Running

On Linux:

$ cd <path-to-QMVC>/viewer
$ ./QMVCViewer

CTRL+Double-left-click opens the controls to load the mesh, the cage, bind them and deform them.

Data set

A set of example models, taken from the paper, is provided in the data direction. See data/README.md for details.

Enabling specific coordinates

At the beginning of CageManipInterface.h you will see the following lines: #define ALLOW_TRI_MVC #define ALLOW_QMVC #define ALLOW_QMVC_MEC // DO NOT COMPUTE QMVC_MEC IF YOU DO NOT COMPUTE QMVC !!!! #define ALLOW_SMVC #define ALLOW_GC

Simply comment the corresponding lines if you do not want to compute the coordinates. By defaults, MVC, QMVC and GC are computed.

QMVC computation usage

See and example of computation of QMVC in viewer/CageManipInterface.h, in the function: computeQMVCCoordinates()
