Testo completoGuay, Martin. "Sketching free-form poses and motions for expressive 3D character animation". Thesis, Université Grenoble Alpes (ComUE), 2015. http://www.theses.fr/2015GRENM016/document.
Testo completoFree-form animation allows for exaggerated and artistic styles of motions such as stretching character limbs and animating imaginary creatures such as dragons. Creating these animations requires tools flexible enough to shape characters into arbitrary poses, and control motion at any instant in time. The current approach to free-form animation is keyframing: a manual task in which animators deform characters at individual instants in time by clicking-and-dragging individual body parts one at a time. While this approach is flexible, it is challenging to create quality animations that follow high-level artistic principles---as keyframing tools only provide localized control both spatially and temporally. When drawing poses and motions, artists rely on different sketch-based abstractions that help fulfill high-level aesthetic and artistic principles. For instance, animators will draw textit{lines of action} to create more readable and textit{expressive} poses. To coordinate movements, animators will sketch textit{motion abstractions} such as semi-circles and loops to coordinate a bouncing and rolling motions. Unfortunately, these drawing tools are not part of the free-form animation tool set today. The fact that we cannot use the same artistic tools for drawing when animating 3D characters has an important consequence: 3D animation tools are not involved in the creative process. Instead, animators create by first drawing on paper, and only later are 3D animation tools used to fulfill the pose or animation. The reason we do not have these artistic tools (the line of action, and motion abstractions) in the current animation tool set is because we lack a formal understanding relating the character's shape---possible over time---to the drawn abstraction's shape. Hence the main contribution of this thesis is a formal understanding of pose and motion abstractions (line of action and motion abstractions) together with a set of algorithms that allow using these tools in a free-form setting. As a result, the techniques described in this thesis allow exaggerated poses and movements that may include squash and stretch, and can be used with various character morphologies. These pose and animation drafting tools can be extended. For instance, an animator can sketch and compose different layers of motion on top of one another, add twist around strokes, or turning the strokes into elastic ribbons. The main contributions of this thesis are summarized as follows: -The line of action facilitating expressive posing by directly sketching the overall flow of the character's pose. -The space-time curve allowing to draft full coordinated movements with a single stroke---applicable to arbitrary characters. -A fast and robust skeletal line matching algorithm that supports squash-and-stretch. -Elastic lines of action with dynamically constrained bones for driving the motion of a multi-legged character with a single moving 2D line

This thesis explores a new type of computer-aided sketching tool for 3-dimensional designs. Sketching, as a process, has been used as an effective way to explore and develop ideas in the design process. However, when designers deal with volumetric designs in 3-dimensional space, current sketching means, including traditional free-hand sketching and contemporary computer-aided design (CAD) modeling have limitations such as dimensional inconsistency, and non-intuitive interactions. By observing the roles of sketching in the design process and reviewing the history of design tools, this thesis investigates and proposes new digital methods of 3-dimensional sketching that take advantage of motion detecting and computer-vision technology that is widely available today. In this thesis, two prototype tools were developed and compared. The first prototype uses a motion detecting sensor, projection screen, and gesture tracking software. The movement of the user's hands becomes the intuitive interface to shape 3-dimensional objects in the virtual space. The second prototype, developed in collaboration with Nagakura, uses a hand-held tablet computer with marker-based augmented reality technique. The hand-held device displays the virtual object from desired angles and works as a virtual tool like a chisel, plane, drill, and glue gun to shape virtual objects in 3-dimensional space. Testing these two prototypes for use, and comparing the resulting objects and user responses revealed the strengths and weaknesses of these different 3-dimensional sketching environments. The proposed systems provide a possible foundation for novel computer-aided sketching application that takes advantages of both the physical and virtual worlds.

Testo completoDigital 3D skissande och modellering är ett fält inom datavetenskap som konstant utvecklas genom nya interaktionsparadigmer. Många lösningar rör sig ifrån de traditionella, moderna, programvarorna för att skapa en mer naturlig och intuitiv användarupplevelse. Denna rapport har som mål att utvärdera en existerande pekskärmslösning gentemot en egen implementation som använder förstärkt verklighet i syfte att efterlikna det sätt vi ritar på i verkligheten. En jämförande uppgiftsbaserad användarstudie genomfördes och kvantitativ data samlades tillsammans med ett frågeformulär och en enkät. Resultaten indikerar att man arbetade snabbare och föredrog några modeller gjorda med den existerande programvaran medan den nya implementationen visade bättre eller likvärdiga resultat gällande den spatiala kognitiva förmågan, frekvensen då man ångrade sig samt återanvändbarhet. Förstärkt verklighet påvisade starka resultat gällande den enklare geometriska pyramidformen men jämförelsevis sämre resultat gällande mindre enhetliga former. Med ytterligare förbättringar så kan förstärkt verklighet ses som ett bra medium för att förbättra viset man skissar och modellerar i 3D.

Testo completoThe increasing accessibility of real-time 3D rendering hardware has made 3D content creation a major means of expression and storytelling. But authoring 3D content requires interacting with the digital representations of shape and appearance that are compatible with rendering and animation algorithms. Triangular meshes, parametric material models and animation curves, while well suited to downstream computation, require artists to convey their ideas in terms of low-level commands that need to be learnt and remembered.In this thesis, we explore the use of 3D strokes as a way for artists to express their ideas. Inspired by the way artists work with brush and canvas, we consider the artist's mark-making gesture as the main input to the authoring system. 3D strokes are flexible primitives that can be created in either 2D desktop user interfaces or in virtual reality (VR) interfaces, and they can encode a 3D shape or likewise the final appearance of a 3D painting. Designing tools that consider 3D strokes as a shape or appearance representation opens a large and exciting space to explore.Designers can use 3D strokes as a partial representation of 3D shape. We investigate how to interpret a sparse 3D sketch into a 3D surface model. Since feature curves are a prominent part of the design and are finely depicted by the sketch, we recover a piece-wise smooth surface that preserves those sharp features. By obtaining a surface from 3D strokes, our algorithm allows to render the shape depicted by the sketch.To better understand how 3D strokes can depict not only the shape but also the appearance of objects, we study the practice of VR painting among a community of artists that work with a commercial VR painting software. Based on this inquiry, we propose a design and implementation for 3D-Layers, a new interaction primitive for VR painting that embraces 3D strokes as the sole representation for both 3D shape and appearance, yet decouples edition of these two elements. Inspired by the usage of layer compositing in 2D digital painting, we support a non-destructive workflow to edit the appearance of a VR painting.Hand-drawn animation is an expressive way to convey an animation with strokes. In “video doodles” animation, artists create an animated doodle that seems to live in the same 3D space as a captured video. Taking into account perspective effects and occlusions while drawing 2D strokes is not an easy task, so we leverage computer vision techniques to place strokes in 3D space and render them with respect to the video context. We design a 2D user interface that resembles traditional 2D motion design tools, to enable usersunfamiliar with 3D tools to create such animations.Overall, we show that 3D strokes are an expressive representation for 3D content creation by proposing three systems that leverage 3D strokes or 3D sketches as interaction primitives for creative applications spanning shape, appearance and animation authoring.We approach system design from two complementary perspectives ; we develop novel algorithms to interpret strokes and low-level user input, and we design interactions to provide new ways for people to express their high-level intent

In this paper, we present a system that gives artists the ability to add ghost effect, speedline and stylized deformation to existing animation sequences in real time, withoutthe need to modify the 3D mesh geometry of the animation sequence. The artist can add and control e��ects using a sketch-based interface, and see the stylized result in real time. With all e��ects and processing o2 oaded to programmable graphics hardware, the proposed system can be implemented with more e±ciency and °exibility.
