We present an algorithm that generates natural and intuitive deformations via direct manipulation for a wide range of shape representations editing scenarios. Our method builds space deformation represented by collection affine transformations organized in graph structure. One transformation is associated with each node applies to the nearby space. Positional constraints are specified on points embedded object. As user manipulates constraints, nonlinear minimization problem solved find...

We present a technique to generalize the 2D painting metaphor 3D that allows artist treat full space as canvas. Strokes painted in viewport window must be embedded way gives creative freedom while maintaining an acceptable level of controllability. address this challenge by proposing canvas concept defined implicitly scalar field. The shapes implicit creating approximate proxy geometry. An optimization procedure is then used embed strokes satisfying different objective criteria on This...

Although animation is one of the most compelling aspects computer graphics, possibilities for depicting movement that make dynamic scenes so exciting remain limited both still images and animations. In our work, we experiment with motion depiction as a first-class entity within rendering process. We extend concept surface shader, which evaluated on an infinitesimal portion object's at instant in time, to programmable effect, global knowledge about all portions pass front pixel during...

Determining one's own position by means of a smartphone is an important issue for various applications in the fields personal navigation or location-based services. Places like large airports, shopping malls extensive underground parking lots require but satellite signals and GPS connection cannot be obtained. Thus, alternative complementary systems are needed. In this paper system concept to integrate foot-mounted inertial measurement unit (IMU) with Android presented. We developed...

This work deals with the development of a comprehensive mean-field dislocation creep model and its application to martensitic 9% Cr-steel P91. Microstructural data from literature, EBSD measurements results precipitate kinetic simulations serve as input for simulation in addition material- physical constants. The has capability calculating curves depending on their initial microstructure, stress temperature is thus able deduce time-to-rupture diagrams. Side-result microstructural evolution...

An important prerequisite for determining whether a certain product is producible in any given production facility an accurate assessment of which lines and/or the machines are able to execute necessary steps. Not only static information about capabilities machines, but also conditions and tools significant this analysis. Because deviation machine with increasing deterioration weary equipment, it continuously monitor status analyze conditions. In paper, we present approach generating plans...

Localization in wireless sensor networks (WSN) based on the evaluation of received signal strength (RSS) values communication packets has a considerable amount research interest last years. In spite number approaches that have been presented, performance most systems remains rather poor due to unpredictable behavior RSS and resulting fluctuating position estimations. this paper, an approach cope with these fluctuations for purpose ad-hoc person localization WSN is presented. A hip-mounted...

In this paper a new concept for an infrastructure independent approach to indoor person localization is outlined. It proposed deploy ad-hoc wireless sensor network (WSN) by means of pedestrian dead reckoning (PDR) unit. The deployed nodes are initialized with PDR-determined position estimation. Furthermore, subset the has GPS connection and thus accurate estimation own position. Within infrastructure, persons that carry on-body can then be localized based on received signal strength (RSS)...

Localization of persons or equipment in ad-hoc scenarios, e.g., after an earthquake still poses many challenges. The popular received signal strength (RSS) based localization methods usually cannot provide the needed accuracy especially if sensor tools are to be localized a static environment with non line sight conditions. On other hand, time-of-flight (ToF) measurements have shown more accurate results but difficulties low power hardware narrow-band wireless systems used. Inadequate timing...

The reduction of CO2 by moving from fossil to renewable energy sources is currently high on the agenda many governments. Simultaneously these governments are also forcing consumption. primary focus agendas mobility, building, and industrial sectors. For latter, energy-efficient shop floors machining processes assist Previous research has focused strategies during processes. However, an start-up machines or their spindle axis been neglected until now. This paper focuses this issue comparing...

Artists explore the visual style of animated characters through 2D concept art, since it affords them a nearly unlimited degree creative freedom. Realizing desired style, however, within 3D character animation pipeline is often impossible, artists must work technical limitations toolset. In order to expand range possible styles for digital characters, our research aims incorporate expressiveness afforded by painting into computer as core component authoring and animation. While prior methods...

Abstract Die Sichtprüfung von Schweißnähten ist die einfachste und am häufigsten durchgeführte Art der Schweißnahtprüfungen. Neben laufenden Soll‐Kontrollen durch das Schweißpersonal während Fertigung abschließend für alle Ausführungsklassen vollumfänglich nach EN 1990‐2 durchzuführen. Dabei können direkte indirekte Prüfmethoden angewendet werden, zu denen auch Geometrieerfassung Laserscanning zählen ist. In diesem Beitrag wird praktische Anwendung eines mobilen Laserscansystems den...

Abstract Processing of liquid silicone rubber (LSR) in the injection molding process has a high economic potential. Since there are some fundamental differences compared to classical thermoplastic molding, up now is lack well‐founded knowledge which allows an estimation cycle time. Because, addition reverse temperature control, LSR processing also involves irreversible temperature‐ and time‐dependent chemical reaction. In this paper, complex cross‐linking reaction first modelled...

An important factor for the success of industrial manufacturers is a cost-efficient, robust and thus failsafe production. In this context topic increasing interest continuous monitoring machine tools to be able proactively react signs degeneration single components ensure technical availability whole plant.

We present a method for rendering 3D paintings by compositing brush strokes embedded in space. The challenge is reconciling conflicts between their z-order and the order which were painted, while maintaining temporal spatial coherence. Our algorithm smoothly transitions closer over those farther away painted later earlier. It efficient, running O(n log n) time, simple to implement. demonstrate its effectiveness on variety of paintings.
