This package contains the code that implements the following paper, 
"Real-time Locally Injective Volumetric Deformation"

What does the code contain.
The app is built with a combination of MATLAB, C++ code and mex/CUDA code. 
The C++ source code for the OpenGL UI with MS Visual Studio C++ project files is in the glvu folder.
The mex/CUDA source code for the GPU accelerated optimization is in the ProjHarmonicMap folder.
The mex/C++ for CPU accelerated optimization is in the utils folder.
Precompiled binary for UI and mex are provided with the package.

Requirements:
Windows 10
MATLAB(>=2019a)
A GLSL 3.3 compatible GPU
CUDA(Compute Capability>3.5)


To run the software:
1.Start MATLAB
2.cd to the code folder
3.call vol_Deformation_main.m. This will automatically open the GUI and load the "animal" model

The User Interface:
4.For deformation, the P2P constraint can be edited by:
	adding P2P constaints by left clicking on the model
	moving the P2P target by dragging and dropping any P2P constraint
	delete constraints by right clicking the P2P constraints
