Physically Realistic Rendering of Complex Materials Using Wave optics
… and immersive virtual environments demand realistic material models that describe how light interacts with them. Important appearance effects are missing in conventional material models due to the built-in ray optics assumption. For example, rendered backlit hair is much dimmer than it is …

Real-time Realistic Rendering And High Dynamic Range Image Display And Compression
… on the many issues that arise from the visual rendering problem. Of primary consideration is light transport simulation, which is known to be computationally expensive. Monte Carlo methods represent a simple and general class of algorithms often used for light transport computation. …

Simulating Real-World Human Activities with VirtualCity: A Large-Scale Embodied Environment for 2D, 3D, and Language-Driven Tasks
… to be learned. Within these simulators, having realistic rendering and physics ensures that the sim2real gap for tasks isn’t too large. Current embodied environments focus mainly on small-scale or low-level tasks, without the capability to learn large-scale diverse tasks, and often lack the …

Designing in virtual reality : tools with the human field of vision
… claims that designers will prefer 3d models with realistic rendering textures in VR, more so than CAD. The fourth and final hypothesis is that architects, familiar with CAD, can design immersive views just from a 3d omniscient plan without immersion, unlike novices. The first part of the research …

Acquisition and modeling of material appearance
In computer graphics, the realistic rendering of synthetic scenes requires a precise description of surface geometry, lighting, and material appearance. While 3D geometry scanning and modeling have advanced significantly in recent years, measurement and modeling of accurate material appearance have …

Recognition, Mining, Synthesis and Estimation (Rmse) for Large-Scale Visual Data Using Multilinear Models
… in object recognition, video mining, image-based rendering, and 3D scene modeling. In object recognition, we present a general framework for dimensionality reduction using Datum-as-Is representation. Our approach works directly on the multi-dimensional form of the data (matrix in 2D and tensor in …

Perceptual models for high-refresh-rate rendering
Rendering realistic images requires substantial computational power. With new high-refresh-rate displays as well as the renaissance of virtual reality (VR) and augmented reality (AR), one cannot expect that GPU performance will scale fast enough to meet the requirements of immersive photo-realistic …

The Development of Landscape Painting Between the Late Gothic Period and the Early Renaissance
… painting landscapes. The research shows that the realistic rendering of natural objects and environments was the necessary initial phase of the development. The impulse to look to nature occurred first in Italy, and was based on the need for empirical illustrations for practical texts. In the …

Development and Demonstration of Scalable Methods for Research on Human Factors in Driving
… factors. The methods that I used included 1) realistic rendering of driving scenarios in computer graphics generated videos, 2) simplified mental workload assessment using ratings of workload associated with driving scenarios (as represented in videos), and 3) a method of synchronized driving …

Wavelets In Real-time Rendering
… natural lighting environment, however, real-time rendering of dynamic scenes still remains a challenging problem. In this dissertation, we propose a systematic approach to render dynamic glossy objects under the general all-frequency lighting environment. In our framework, lighting integration is …

Performance Improvements for the Rasterization Pipeline
… we are still far from the point where photo-realistic rendering can be done in real time. Therefore, better algorithms must be developed in order to advance the field. In this thesis, we present several new algorithms targeted for the rasterization pipeline, which is, at the time of writing, …

Generalizable and Efficient Novel View Synthesis with Perceptual Foundations
… by improving reconstruction robustness, boosting rendering efficiency, and incorporating support for dynamic scenes, while also providing a systematic analysis of the perceptual soundness of current techniques. These advancements aim to make novel view synthesis practical, enabling users to …

Fast Algorithms For Fragment Based Completion In Images Of Natural Scenes
… to represent fine visual details and produce realistic looking images. Often it is necessary to remove some foreground object from the scene. Removal of the portion creates one or more holes in the texture image. These holes need to be filled to complete the image. Various methods like clone …

Kvalitní zobrazení stínů pro složité světelné zdroje
V interaktivních aplikacích jsou stíny tradičně zobrazovány s pomocí algoritmu založeným na stínových mapách. Nevýhodou toho algoritmu je, že stínová mapa, reprezentovaná texturou, má pouze omezené rozlišení. To může vést k nepěkným vizuálním artefaktům objevujících se na hranách stínů. Tato práce …
