Breaking the Pixel: Component-Based Rendering Systems

Breaking the Pixel: Component-Based Rendering Systems

ABSTRACT:

Due to ray-tracing having linear complexity to the number of pixels rendered or rays shot, traditional rendering systems attempt to reduce number of primary rays shot. [...] By considering that at each intersection point the reflectance function of the medium is calculated by shooting rays to simulate different properties of the material we can use the individual rays from one intersection point to the next as a finer level of granularity. In this talk we investigate this approach termed component-based rendering and highlight the advantages of adopting a finer level of granularity by removing the recursion when required. We present a framework for component-based rendering which allows the user to control the desired transport equation using a regular expression. This technique is further extended to progressive rendering, time-constrained rendering and perceptually-based rendering.
