// Compute dispatcher : allows client code to customize parts or the entire
|
|
// computation process. This pattern aims at hiding the logic specific to
|
|
// the subdivision algorithms and expose a simplified access to minimalistic
|
|
// compute kernels. By default, meshes revert to a default dispatcher that
|
|
// implements single-threaded CPU kernels.
|
|
//
|
|
// - derive a dispatcher class from this one
|
|
// - override the virtual functions
|
|
// - pass the derived dispatcher to the factory (one instance can be shared by many meshes)
|
|
// - call the FarMesh::Subdivide() to trigger computations
|
|
//
|
|
// Note : the caller is responsible for deleting a custom dispatcher
