The main part of the library is implemented in the C++ Mesh<...> classes that follow the following inheritence rules:
This scheme and detailed technical description of the classes are provided as a Doxygen documentation (see ../README.md for how to generate documentation).
In the graph above, the root node (i.e., Mesh) and leave nodes can be instanciated, while the intermediate levels are pure virtual (or abstract) classes. Examples of how to use them are provided in the examples of this repository.
- Mesh is the base class representing a mesh. It can be instanciated as is.
- Mesh_Subdiv extends the Mesh class (i.e., it inherits from it) and is a virtual (or abstract). It defines the methods that necessarily have to be implemented for any class that proposes subdivision routines (and inherits from it).
- Mesh_Subdiv_CPU and Mesh_Subdiv_GPU extend Mesh_Subdiv and are pure virtual too. They add requirements and implementations for CPU-backend and GPU-backend subdivision methods, respectively.
- Mesh_Subdiv_Loop and Mesh_Subdiv_Catmull-Clark extend Mesh_Subdiv and are pure virtual too. They add add requirements and implementations for the Loop and Catmull-Clark subdivision schemes, respectively.
- Finally, the four leave classes derive from two pure virtual classes: one among Mesh_Subdiv_Loop and Mesh_Subdiv_CatmullClark, and one among Mesh_Subdiv_CPU and Mesh_Subdiv_GPU and fully implement a subdivision solution for either Loop or Catmull-Clark subdivision on either the CPU or GPU backend.
