Nokia reveals plans for Qt

Caroline Gabriel, Rethink Wireless
Nokia's operating system strategy remains a work in progress and with new faces at most levels of its management, we are sure to see some rebalancing of its three key platforms - Symbian^3, MeeGo and Series 40.
 
That makes its underestimated but critical cross-OS developer framework, Qt, even more important. The firm held a Qt developer day in Munich, Germany this week to outline the future of the platform.
 
It was a sign of how preoccupied observers are with the OS wars, that this briefing - potentially far more decisive for Nokia's future success than its individual operating systems - that it gained very little coverage.
 
Overshadowed by the WP7 launch, Nokia's VP of application and service frameworks, Sebastian Nyström, and the R&D director for Qt Lars Knoll sketched the future of their technology.
 
The main priority is to boost performance, which the executives admitted was the main area of developer requests. As H-Online explains, the plan is to accelerate Qt with a new feature called Qt Scene Graph, which will streamline the graphics rendering pipeline from three stages to one, fully exploiting graphics processor acceleration where available.
 
This will be important for games and other multimedia apps, on the rising number of mobile devices that will boast dedicated GPUs.
 
Another project that is near commercialization is Lighthouse, which supports similar hardware acceleration for developers of embedded devices.
