Can I do this? Or is there a better way?
I've written an QGLWidget desktop image display and enhancement tool using OpenGL shaders. I would like to webify it and use WebGL for the "enhancements". But because of the same domain issue (unless you play serious tricks with the browsers, they can't open a disk file from the same domain the html file is on), I need a server back end that can open the file and send pixels through a websocket transport mechanism. My viewer also works with non-WebGL native formats which use existing c++ libraries to read and get to the pixels. So I need the highest bandwidth binary blob transport that WebSockets can do.
Is QWebChannel the answer? Can I set up a bidirectional connection between a browser and my c++ server and send tiles of pixels to the browser client with high speed?
Advice greatly appreciated.
