Nowadays, there is a strong trend towards rendering to higher-resolution
displays and at high frame rates. This development aims at delivering
more detail and better accuracy, but it also comes at a significant
cost. Although graphics cards continue to evolve with an ever-increasing
amount of computational power, the processing gain is counteracted
to a high degree by increasingly complex and sophisticated pixel
computations. For real-time applications, the direct consequence is that
image resolution and temporal resolution are often the first candidates to
bow to the performance constraints (e.g., although full HD is possible,
PS3 and XBox often render at lower resolutions). In order to achieve
high-quality rendering at a lower cost, one can exploit temporal coherence
(TC). The underlying observation is that a higher resolution and frame
rate do not necessarily imply a much higher workload, but a larger
amount of redundancy and a higher potential for amortizing rendering
over several frames. In this session, we will investigate methods that
make use of this principle and provide practical and theoretical advice
on how to exploit temporal coherence for performance optimization. These
methods not only allow us to incorporate more computationally intensive
shading effects into many existing applications, but also offer exciting
opportunities for extending high-end graphics applications to lower-spec
consumer-level hardware.
