|
* JS BINDINGS DESIGN
|
|
* ------------------
|
|
*
|
|
* The purpose of filament-js is to offer a first-class JavaScript interface to the core Filament
|
|
* classes: Engine, Renderer, Texture, etc.
|
|
*
|
|
* Emscripten offers two ways to binding JavaScript to C++: embind and WebIDL. We chose embind.
|
|
*
|
|
* With WebIDL, we would need to author WebIDL files and generate opaque C++ from the IDL, which
|
|
* complicates the build process and ultimately results in the same amount of code. Using embind is
|
|
* more direct and controllable.
|
|
*
|
|
* For nested classes, we use $ as the separator character because embind does not support nested
|
|
* classes and it would transform dot separators into $ anyway. By using $, we at least make
|
|
* this explicit rather than mysterious.
|
