This repository contains the official implementation of our paper "Time-Varying Coronary Artery Deformation: A Dynamic Skinning Framework for Surgical Training", submitted to International Journal of Computer Assisted Radiology and Surgery.

Note: The complete code will be released upon paper acceptance.

Features

• Skeleton-based real-time deformation
• Animation sequence playback for vessel deformation
• Interactive skeletal control
• Visualization debugging tools
• Export capabilities for deformed meshes and pose data

Requirements

System Requirements

• Windows/Linux/MacOS
• OpenGL support
• C++ compilation environment

Dependencies

• Eigen 3.3+
• libigl
• GLUT
• AntTweakBar
• CGAL (optional, for mesh processing)
• TetGen (optional, for tetrahedral meshing)

Installation

mkdir build
cd build
cmake ..
make

Usage

-Mouse Controls:

	Left Click + Drag: Select and control bones
	Alt + Left Drag: Rotate scene
	Mouse Wheel: Zoom in/out

-Keyboard Shortcuts:

	A/a: Toggle animation play/pause
	D/d: Deselect all
	e: Set rotation control mode
	w: Set translation control mode
	R: Reset selected bone rotation
	r: Reset all bone rotations
	F/f: Toggle floor display
	S: Save current posed mesh
	s: Save current skeleton pose
	W: Save current weights
	Z/z: Snap to canonical view
	Ctrl+Z: Undo
	Ctrl+Shift+Z: Redo
	ESC/Ctrl+C: Exit program

-File Formats

	Supported Mesh Formats: .obj, .off
	Skeleton File Format: .tgf
	Weight File Format: .dmat
	Output Formats:
		-Mesh: .obj
		-Pose: .dmat
		-Weights: .dmat
		
-Command Line Arguments

	./program <model.obj> <skeleton.tgf> [weights.dmat] [pose-prefix]
	Parameters:
		-model.obj: Input mesh model file
		-skeleton.tgf: Skeleton file
		-weights.dmat: (optional) Weight file
		-pose-prefix: (optional) Prefix for output pose files

Important Notes

• Ensure correct format for input models and skeleton files
• Large models may require longer initialization time
• Recommended to save weight files to avoid recalculation
• Adjust model resolution if performance issues occur
