Fast Colored Surface Rendering for Entertainment Applications on Small Devices - An Experimental Study

The actual small devices, such as smartphones, PDAs, and handheld devices, represent a challenging scenario. The applications running on those devices require a trade--off between the responsiveness felt by the user, and the onboard computational power. The latter resembles to the computational power of the early 90's computers. Therefore, this kind of hardware is inadequate to support the same solutions adopted by the actual personal computers. This paper emphasizes the usage of colors and wire--frame visualization as an effective solution to the above limitations. The focus of this work is on the visualization of bivariate function surfaces. This proposal allows both an high visual impact, still remaining fast and accurate, both the fast rendering of scenarios in several entertainment applications. The proposed visualization technique provides color visualization and is faster than any other presented in literature. The experiments here shown refer to the implementation of this proposal by means of the Java programming language, and to its execution into a smartphone.
