3D computer graphics have existed for decades, and these days are almost an accepted ability of any digital platform – from phone to tablet, laptop to desktop pc. Even with the vast amount of power in today’s generation of devices, there has always been some upper limit to work around, made all the more complex by the breadth of GPU processors in circulation. In the multi-platform world of today, consistency is the new holy grail – the ability to maintain a quality of performance across many different devices. In this session, Rob explores some of the tricks of the trade that can help release the 3D developer from their never-ending battle between performance and quality.
