“…These algorithms only use two discrete camera locations (one per eye location) instead of a full camera line. Havran et al [16] divide shaders into a view-dependent and a view-independent part, and reuse the latter of these between frames in animation. This technique resembles our shader reuse over the camera line.…”

“…In the simplest implementation, we divide the shader into a view-dependent (V D ) and a view-independent (V I ) part [16,20]. For every back tracing sample, the V D part of the BRDF is evaluated.…”

“…Ward and Simmons [WS99] and Bala et al [BDT99] store and reuse previously rendered rays. Havran et al [HDM03] calculate the temporal interval over which a given sample will remain visible in an offline animation and reproject that sample during the interval, recalculating shading for all reprojected samples in every frame.…”

Improving Interactive RenderingIn recent years a number of traditionally offline rendering algorithms have become interactive or nearly so. The introduction of programmable high-precision graphics processors (GPUs) has drastically expanded the range of algorithms that can be employed in real-time graphics; meanwhile, the steady progress of Moore's Law has made techniques such as ray tracing, long considered a slow algorithm suited only for offline realistic rendering, feasible in real-time rendering settings. These trends are related; indeed, some interactive global illumination research performs algorithms such as ray tracing and photon mapping directly on the GPU [PBMH02]. Future hardware should provide even better support for these algorithms, bringing us closer to the day when ray-based algorithms are an accepted and powerful component of every interactive rendering system.What makes interactive ray tracing attractive? Researchers in the area have commented on ray tracing's ability to model physically accurate global illumination phenomena, its easy applicability to different shaders and primitives, and its output-sensitive running time, which is only weakly dependent on scene complexity [WPS*03]. We focus on another unique capability: selective sampling of the image plane. By design, depth-buffered rasterization must generate an entire image at a given time, but ray-tracing can focus rendering with very fine granularity. This ability enables a new approach to rendering that is both more interactive and more accurate.The topic of sampling in ray tracing may seem nearly exhausted, but most previous work has focused on spatial (right). Resulting imagery has similar visual quality to a framed renderer but is produced using an order of magnitude fewer samples per second.

“…In this section we consider a view-dependent algorithm called bi-directional path tracing (BPT) [Lafortune 1996;Veach 1997] which we extend to handle dynamic environments [Havran et al 2003]. In this algorithm, the bookkeeping of global illumination samples is organized in the image space.…”

Producing high quality animations featuring rich object appearance and compelling lighting effects is very time consuming using traditional frame-by-frame rendering systems. In this paper we present a number of global illumination and rendering solutions that exploit temporal coherence in lighting distribution for subsequent frames to improve the computation performance and overall animation quality. Our strategy relies on extending into temporal domain well-known global illumination techniques such as density estimation photon tracing, photon mapping, and bi-directional path tracing, which were originally designed to handle static scenes only.
