OpenRV-annotation

OpenRV-annotation is a C++ annotation geometry library. It produces triangle-ribbon path geometry (TwkPaint::Path), physics-based input smoothing (TwkPaint::Smoother), and stamp-based brush placement (TwkPaint::StampPath) for use as inputs to a renderer of your choice. Also includes shared GLSL shaders and brush tip assets. Used natively by OpenRV and compiled to WebAssembly for Creative Review via OpenRV-annotation-wasm.
