How to compile google filament to wasm for windows?

[amarav]

I would like to know how to compile the filament to wasm in Windows. The readme describes only for linux / macOs. Could anyone help with this?

@amarav This is not the way to build it, but you can get the Nightly Build version of wasm from

https://github.com/google/filament/actions?query=workflow%3AWeb

@cx20 Thanku so much for sharing! I tried to view the sample https://github.com/google/filament/blob/main/web/docs/tutorial_triangle.md in browser but cant see anything... Could you share a simple program which uses this for me to understand the flow? Sorry im new to these,,,

Currently, Triangle samples do not work on Chrome 88 in Filament v1.9.10.
It will be fixed in Filament v1.9.11, but if you want to try it right away, try Firefox.

The following is the display result in Firefox 85.

@cx20 Can you share some inputs on how the canvas is allocated on the browser and how the filament apis are bind with JS using embind?

May I know if you have used opengl es2 ?

I don't know much about OpenGL, but looking at the #include in the sample code, it looks like it uses OpenGL ES2.

Also, may i know why you have used USE_GLFW=3 for compilation in

What does that mean?
I think I'm using that parameter to try to use the latest version of GLFW.

[amarav]

ok. Thank you so much!
Sorry for asking too many questions.
Is there a way to debug wasm / emscripten ?

[cx20]

I'm sorry, I've only tried Hello World in Emscripten, so I don't know how to debug it.

I just googled it, but the following may be helpful.
