abstract = "High-fidelity renderings of virtual environments is a notoriously
computationally expensive task. One commonly used method to
alleviate the costs is to adaptively sample the rendered images
identifying the required number of samples according to the
variance of the area thus reducing aliasing and concurrently
reducing the total number of rays shot. When using ray tracing
algorithms, the traditional method is to shoot a number of rays
and depending on the difference between the radiance of the
samples further rays may be shot. This approach fails to take into
account that different components of a material reflecting light
may exhibit more coherence than others. With this in mind we
present a component-based adaptive sampling algorithm that renders
components individually and adaptively samples at the component
level, finally composting the result to produce a full solution.
Results demonstrate a significant improvement in performance
without any perceptual loss in quality.",
