i am new in this forum. I am working on one OpenGL Application that renders a 3D objects on the browser. The objects should be render in such a way that we feel objects are overlayed on the browser windows. There are many options are there but the critical part is that i want cross-platform solution.
Spy++ does wonders . Use against sites, where Flash animations are overlayed (maybe different window-styles), or installed plugins (unitywebplayer/divx).
But I bet there is no single solution to cover the major platforms and major browsers on each of these platforms, or at least 3 of the permutations at once.
