:lollipop: Physically plausible interactive 3D mesh deformation based on as rigid as possible constraints.

mesh-deform

mesh-deform is cross-platform C++11 library capable of deforming meshes under rigidity constraints, leading to an interactive visually appealing (not necessarily physically correct) surface modeling approach.

The implementation is based on Sorkine, Olga, and Marc Alexa. "As-rigid-as-possible surface modeling." Symposium on Geometry processing. Vol. 4. 2007.

Features

• Mesh independent implementation running interactive frame rates
• Keyframe-based 6DoF trajectory interpolation
• OpenMesh surface adapter
• Visualizer

Compilation

mesh-deform is a header only project requiring the following dependencies:

• Eigen: http://eigen.tuxfamily.org/

Optionally:

• Sophus: https://github.com/stevenlovegrove/Sophus/
• OpenMesh: https://www.openmesh.org/
• OSG: http://www.openscenegraph.org/

Getting started

You may want to browse the source of one of the examples to get a feeling for how this library is meant to be used.

The basic procedure is: Given a source mesh, a set of handles that are said to be fixed in space, another set of handles dragged to an offset position the library iteratively computes the positions of the remaining vertices so that every vertex is moved as rigid as possible given its direct neighborhood.

mesh-deform's Issues

can your code only apply to 2D mesh? How to achieve this?

I want to apply deform to 2D mesh, how to achieve this?

Besides, how to compile without open-mesh, osg and Sophus? Are they enssential to 2D mesh deform?

Does this algorithm work for open surfaces?

By open surface I mean the triangle mesh with border edges.

When I try to deform my mesh, setupLinearSystem() doesn't solve.
That is why I am wondering, it happens because my mesh is open, flat piece of surface, not like sphere in you example.

Thank you,
Oleg
