Live Draw Harness demos provide code snippets for learning Open CASCADE Technology (or OCCT) framework. Each example defines a C++ code snippet elaborating a particular class or algorithm, as well as a Tcl script for Draw Harness application.
Draw Harness scripts (Tcl) are run directly on a page, allowing users to see an output of executed algorithms within emulated Terminal as well as within interactive WebGL 3D Viewer. WebAssembly support in modern Browsers makes it possible to use C++ libraries like OCCT in web applications in a portable manner without installation of any native plugins or backing libraries on a server side.
