Inverse Anatomical Modeling and Simulation of Virtual Humans
Kadleček, Petr ; Kavan, Ladislav (advisor) ; Bickel, Bernd (referee) ; Botsch, Mario (referee)
Title: Inverse Anatomical Modeling and Simulation of Virtual Humans Author: RNDr. Petr Kadleček Department: Department of Software and Computer Science Education Supervisor: Mgr. Ladislav Kavan, Ph.D., Department of Software and Computer Science Education Abstract: In this dissertation, we focus on a mechanical aspect of a human body and face modeling. We leverage existing physics-based models of elasticity and use them as building blocks to create an animatable virtual human. We model different types of hard and soft tissues to enable our model to contract muscles, interact with an environment or realistically deform when subjected to external forces. In the first part of the work, we present a method to create personalized anatom- ical models of human body ready for physics-based animation, using only a set of 3D surface scans. We start by building a template anatomical model of an average male which supports deformations due to both 1) subject-specific vari- ations: shapes and sizes of bones, muscles, and adipose tissues and 2) skeletal poses. Next, we capture a set of 3D scans of an actor in various poses. Our key contribution is formulating and solving a large-scale optimization problem where we compute both subject-specific and pose-dependent parameters such that our resulting anatomical model...

Haptic rendering for 6/3-DOF haptic devices
Kadleček, Petr
Application of haptic devices expanded to fields like virtual manufacturing, virtual assembly or medical simulations. Advances in development of haptic devices have resulted in a wide distribution of assymetric 6/3-DOF haptic devices. However, current haptic rendering algorithms work correctly only for symmetric devices. This thesis analyzes 3-DOF and 6-DOF haptic rendering algorithms and proposes an algorithm for 6/3-DOF haptic rendering involving pseudo-haptics. The 6/3-DOF haptic rendering algorithm is implemented based on the previous analysis and tested in a user study.

Adaptive Simulation of Large-Scale Ocean Surface
Krijt, Filip ; Kadleček, Petr (advisor)
Physically-driven methods of simulating fluid dynamics and frequency-based ocean surface synthesis methods are of long-standing interest for the field of computer graphics. However, they have been historically used separately or without any interaction between them. This thesis focuses on the possibility of combining the approaches into one adaptive solution by proposing methods for unified surface representation, method result blending and one-way interaction between the methods. The thesis also outlines several future developments of the combined method and proposes a level-of-detail approach taking advantage of hardware tessellation that can be used regardless of what method was used for the simulation.

Metadata and Accessing Information on the Internet
Kadleček, Petr ; Sklenák, Vilém (advisor) ; Šubrta, Václav (referee)
The aim of my bachelor thesis is to introduce the reader to the possible ways of creating metadata in the environment of popular CMS and communicate my personal opinions on the influence of metadata on information searches in the environment of WWW services. The first chapter introduces basic information on metadata, their development, their classification and ways of application. The main focus lies on HTML element meta. At the end of the chapter I ponder the future of semantic approach to web. The second chapter informs the reader about the issue of searching information in WWW environment. The beginning of the chapter defines the basic concepts, then follows the description of function of internet search engines and at the end deals with the SEO issue and its relation to metadata. The last chapter describes the most popular CMS and their interaction with metadata. It opens with practical illustration in the WordPress system a closes with theoretical description of its competition. After reading this theses the readers should understand what metadata are, why they should use them, and how to implement them in their own web pages using CMS.
