The benefits that WebAssembly promises shall be tested in two seperate web pages. One for the performance measurements and one to test the integration of existing libraries.
\paragraph{Performance}
As it is the most applicated algorithm the Douglas-Peucker algorithm will be used for measuring performance. A JavaScript implementation is quickly found. SimplifyJS. It is used by Turf, a geospatial analysis library. To produce comparable results the implementation will be based on this package. A separate library, called SimplifyWASM, written in C will be created that mimics the JavaScript original.
\paragraph{Integrating an existing C++ library}
An existing implementation of several simplification algorithms has been found in the C++ ecosystem. \textsf{psimpl} implements 8 algorithms distributed as a single header file. It also provides a function for measuring positional errors making it ideal for use in a quality analysis tool for those algorithms.
