AssortedWidget, an OpenGL C++ GUI ported to WASM

[Bill Yan]

Hello,

I'd like to show you my old opengl es 2 gui library ported to WASM, with a live demo.

Thanks!

Nice :) The rendering is a bit blurry for me in Chrome, does it look the same as in a native demo? I'm asking because I had the same trouble when porting other UI toolkits over to asm.js (Turbobadger, ImGui and Nuklear). They looked crisp in their native versions, but blurry in the browser. There were 2 main reasons for this: first I had to make sure that the no scaling was happening between the rendered image (in the engine), and the presented image in the browser canvas), and second, more importantly: most (all?) browsers use linear filtering when composing the WebGL canvas to the HTML page, this must be disabled via CSS. The only browser where I couldn't get rid of the blurryness was Safari since the CSS tricks don't work there :/

Here are the demos I mentioned for reference:
