CoRCalculator - Library to Compute Centres of Rotation for Optimised Centres of Rotation Skinning
An example on how to use the library is given in example.cpp.
The CMake file is tested on Linux and Windows.
When compiled with the flag COR_ENABLE_PROFILING, the CoRCalculator will print the times it has needed for each step.
The library has to be linked with the option -pthread, as it uses multithreading (std::async).
This library solely depends on the header-only library glm.
On Linux, installing libglm-dev with apt suffices.
On Windows, finding glm may require some changes, as we do it manually.
We provide GLSL vertex shader logic for these three skeletal skinning techniques:
- Linear Blend Skinning (LBS)
- Dual Quaternion Skinning (DQS)
- Optimised Centres of Rotation Skinning (CRS).
The file skeletons.glsl contains the perform_skinning function, that computes one of these three methods, depending on a uniform variable.
The files quaternion.glsl and dualquaternion.glsl each contain utility functions for their respective mathematics and have to be compiled
together with the vertex shader because they are required by skeletons.glsl.
We split these files so that you may pick what you need, since the skeletons.glsl file has to be customized anyway (especially the layout locations of the attributes).
