This repository contains the code of our Bachelor's Honours Programme research on voxel animation/deformation. Volumetric models are deformed through a Spline map (inspired by the Shell map), in which sampled coordinates are transformed according to splines.
Refer to the paper and code for more details on the method and algorithm:
[Paper]: Spline Based Shell Mapping for Smooth Voxel Deformation
Beware that this was our first 'real' paper, so the writing is not quite up to standard.
Source code: src/
Shaders: assets/*.{vert,frag}
Data: assets/
2d version: 2d_debug/
External libraries: external/
The entire rendering algorithm is contained within assets/spline_map.frag, where the uniforms are supplied from src/scene/spline_map_scene.hpp.
Debug code for most of the rendering algorithm is available in src.
To build the project, first run Premake, see https://premake.github.io/. This can be downloaded from the website or through your favorite package manager.
Commands:
- Visual Studio 2017: premake5.exe vs2017
- Makefiles: ./premake5 gmake2
Once the build files have been generated, you can build the project.
- Windows: Use the provided Visual Studio solution (SimpleVolume.sln)
- Linux: Use the included make files (just run
make).
- Hold left mouse button to orbit camera
- WASD to move the camera around
- Scroll wheel to move closer/further
- Escape to escape
- TAB to enter debug mode
- Space to emit debug rays
- Backspace to return to the camera transformation from where the debug rays were emitted
