“…Some of this work is particularly relevant, and we make detailed comparisons to three important examples. The Render Cache by Walter et al [WDP99;WDG02] is most closely related to our work; it reprojects samples each frame to account for camera motion and applies an image-space filter to reconstruct. The Tapestry system by Simmons and Séquin [SS00], and the Shading Cache by Tolé et al [TPWG02] both integrate new samples into 3D meshes to use hardware-accelerated projection and Gouraud shading for image reconstruction.…”

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 our system, indirect directional (nondiffuse) illumination is captured in the radiosity solution, but not direct directional reflection, that is, (L|D)S + E paths. This can be done interactively by ray-tracing, using a method such as the Render-Cache [Walter et al 1999]. The simplest way to achieve interactive display is to use standard graphics hardware to render the view-independent part of the image (i.e., the mesh representing the solution of the unified algorithm), then to compute a texture containing the view-dependent part with the Render-Cache, and finally to use the graphics hardware to blend (add) the two components (see Figure 4).…”

In the past twenty years, many algorithms have been proposed to compute global illumination in synthetic scenes. Typically, such approaches can deal with specific lighting configurations, but often have difficulties with others. In this article, we present a final reconstruction step for a novel unified approach to global illumination that automatically detects different types of light transfer and uses the appropriate method in a closely-integrated manner. With our approach, we can deal with difficult lighting configurations such as indirect nondiffuse illumination. The first step of this algorithm consists in a view-independent solution based on hierarchical radiosity with clustering, integrated with particle tracing. This first pass results in solutions containing directional effects such as caustics, which can be interactively rendered. The second step consists of a view-dependent final reconstruction that uses all existing information to compute higher quality, ray-traced images.

“…In contrast, we will be using hierarchical radiosity with clustering, which deals with these configurations efficiently. Some attempts have also been made for interactive display of globally illuminated scenes [29,32].…”
