Hi, I am interested on working on Qt Quick 2 Scenegraph OpenVG rendering backend. Few embedded devices have both OpenVG and OpenGL accelerators available.
There are few interesting use cases for embedded devices: * 2 display configurations, draw one with OpenVG and one with OpenGL * OpenVG consumes less power, draw some applications with OpenVG. For example more complex idle screen. * Composite both OpenVG and OpenGL renderings into same display. Idea here is that real-time critical items are rendered with OpenVG and non-critical stuff with OpenGL In Qt4 there was a OpenVG rendering backend, but that of course does not fit directly into Scenegraph. Also I found that there has been a plan for this kind of functionality in Qt Conference 2012, but I could not find any results. Is there some (even partial) results available somewhere ? How about technical feasibility. Scenegraph type rendering is in general doable with OpenVG. The backend would need re-implementation to use OpenVG primitives instead of OpenGL (ES). In general I think it should be doable. Any opinions or possible pitfalls ?
