- Standardize `EvalD0/EvalD1/EvalD2/EvalD3/EvalDN` parameter names to `theU` / `theV` (and `theN`, `theNu`, `theNv`) across multiple curve/surface adaptor classes. - Update method signatures to use `const double` / `const int` (top-level const) and add local aliases where needed to preserve existing internal variable naming. - Fix MSVC-warning-prone types/usages in `VrmlData_Scene::readLine()` (use `std::streamsize`, `std::ios::iostate`).
