Information is the third essence in modeling the natural world. This paper attempts to explore
an emerging discipline know as cognitive informatics. Cognitive Informatics is a profound …

The limited resolution of shadow maps (SM) may result in erroneous shadowing, yielding
artificially jagged edges and temporally crawling shadows even using perspective …

This course provides an overview of efficient, real-time shadow algorithms. It presents the
theoretical background but also discusses implementation details for facilitating efficient …

A prediction method generates a fragment number map having a predetermined number of
pixels and a mipmap of the fragment number map, and for a pixel of one layer in the …

Hybrid rendering combines the speed of raster-based rendering with the photorealism of ray
trace rendering in order to achieve both speed and visual quality for interactive applications …

This paper proposes an adaptive rendering technique for ray‐bundle tracing. Ray‐bundle
tracing can be done by per‐pixel linked‐list construction on a GPU rasterization pipeline …

This paper presents an in depth comparison of state‐of‐the‐art precise shadowing
techniques for an omnidirectional point light. We chose several types of modern shadowing …

The paper considers the task of real-time rendering of dynamic relief shadows based on ray
casting using origin relief data-detailed height map. The solution proposed is based on …

针对阴影图算法中的走样和深度偏移的问题, 使用离散的场景原始三角面片来表示和记录阴影
遮挡物的信息, 提出一种几何阴影图算法. 由于遮挡物的深度值能够通过这种原始的连续几何 …

This paper considers the task of real-time modeling of dynamic terrain shadows based on
multilevel ray casting. A technology is proposed, where per-pixel detail controlling of …
