“…However, they emphasized more on the temporal processing of lighting, while our current framework simultaneously considers the visibility and shading aspects of motion blur. A comprehensive survey of motion blur techniques is provided in the recent paper by Sung et al 32 . In Section 7.1 we compare our technique with the most advanced solutions used in Maya Rendering system 32 and PhotorealisticRenderMan (PRMan) 11, 2 .…”

“…Current standard industrial solutions such as PhotorealisticRenderMan 2 , Maya Rendering System 32 , or Softimage process all frames independently one after another. The academic research on rendering architectures is focused mostly on designing object-oriented frameworks which offer high flexibility in handling various shape modeling and appearance rendering techniques (refer to 15 for a recent overview of such frameworks).…”

“…There are a few methods for approximating defocus and motion blur effects [Sung et al 2002;Demers 2004;Kass et al 2006;Lee et al 2009]. These methods are designed to achieve high performance and may produce artifacts in some image regions.…”

(a) Perfect focus (b) Motion blur + defocus AbstractWe present a micropolygon ray tracing algorithm that is capable of efficiently rendering high quality defocus and motion blur effects. A key component of our algorithm is a BVH (bounding volume hierarchy) based on 4D hyper-trapezoids that project into 3D OBBs (oriented bounding boxes) in spatial dimensions. This acceleration structure is able to provide tight bounding volumes for scene geometries, and is thus efficient in pruning intersection tests during ray traversal. More importantly, it can exploit the natural coherence on the time dimension in motion blurred scenes. The structure can be quickly constructed by utilizing the micropolygon grids generated during micropolygon tessellation. Ray tracing of defocused and motion blurred scenes is efficiently performed by traversing the structure. Both the BVH construction and ray traversal are easily implemented on GPUs and integrated into a GPU-based micropolygon renderer. In our experiments, our ray tracer performs up to an order of magnitude faster than the state-of-art rasterizers while consistently delivering an image quality equivalent to a maximumquality rasterizer. We also demonstrate that the ray tracing algorithm can be extended to handle a variety of effects, such as secondary ray effects and transparency.
