A fast simple method for dynamic textures enlargement and editing is presented. The resulting edited dynamic texture is a mixture of several color dynamic textures that realistically matches the given color textures appearance and respects their original optical flows. The method simultaneously allows to spatially and temporarily enlarge the original dynamic textures to fill any required four dimensional dynamic texture space. The method is based on a generalization of the prominent static double toroid-shaped texture modeling roller method to the dynamic texture domain. The presented method keeps the original static texture roller principle of separated analysis and synthesis parts of the algorithm. In its analytical step, the input textures patches are found by an optimal overlap tiling and the subsequent minimum boundary cut. The optimal toroid-shaped dynamic texture patches are created in each spatial and time dimension, respectively. The spatial dimension tile border is derived by textural features, color-tone, and the minimal overlapping error. The time dimension tile border is detected by minimizing the overlapping error and using the input textures optical flow. The realistic appearance of the dynamic textures mix requires to edit the patch color space and to find border patches which consists from more than one type of the texture. These border patches are found similarly to the multi-texture analysis patch step. Since all time-consuming processing, such as the finding of optimal spatio-temporal triple toroidal patches, are done in the analytical step which is completely separated from synthesis part, the synthesis of the edited and enlarged resulting texture can by done very efficiently by applying simple set of repeating rules for these triple toroidal patches. Thus the presented method is extremely fast and capable to synthesize a learned natural dynamic texture spatially and its time span in real-time.

Physically-based rendering systems use proprietary scene description formats. Thus, by selecting a given renderer for the development of a new technique, one is often constrained to test and demonstrate it on the limited set of test scenes available for that particular renderer. This makes it difficult to compare techniques implemented on different systems. We present a solution for automatic conversion among scene description formats used by physically-based rendering systems. It enables algorithms implemented on different renderers to be tested on the same scene, providing better means of assessing their strengths and limitations. Our system can be integrated with development and benchmarking APIs, lending to full orthogonality among algorithms, rendering systems, and scene files.

Lighting intentions are the goals and constraints that designers like to achieve in a lighting design process. In this context, rendering problems are the kind of problems based on the rendering equation that are proposed to satisfy a set of lighting intentions. These problems are usually expressed as optimization problems. In this article is presented a novel method based on photon tracing, the VNS optimization metaheuristic, and the determination of the number of photons needed, which allows to handle a wider variety of lighting intentions without incurring in high computational costs. Moreover, the method developed shows to be efficient when the geometry is also a variable in the rendering problem. The techniques explained here could be included in a package used by architects or designers to aid in the lighting design process of architectural environments.
