Diffusion Based Vector Graphics on Mobile Devices

As a complementary representation, vector graphics gains advantages over raster graphics for its compactness, flexibility etc. However, the support of vector graphics on mobile devices is quite limited, especially for those with complex colour transitions. Under the relatively limited bandwidth and high mobile internet charges, it appears even more urgent. In this paper, we investigate the possibility of supporting diffusion based vector graphics on mobile devices. A whole pipeline of diffusion curves (a popular, novel vector graph representation) is realized on both mobile CPU and GPU to provide display support of vector graphics on mobile devices. We also compare the performance among different computational units on mobile devices and PC, and gain some useful conclusions which will shed light on the future research in this area.
