DeepSketchHair: Deep Sketch-based 3D Hair Modeling
We present sketchhair, a deep learning based tool for interactive modeling of
3D hair from 2D sketches. Given a 3D bust model as reference, our sketching
system takes as input a user-drawn sketch (consisting of hair contour and a few
strokes indicating the hair growing direction within a hair region), and
automatically generates a 3D hair model, which matches the input sketch both
globally and locally. The key enablers of our system are two carefully designed
neural networks, namely, S2ONet, which converts an input sketch to a dense 2D
hair orientation field; and O2VNet, which maps the 2D orientation field to a 3D
vector field. Our system also supports hair editing with additional sketches in
new views. This is enabled by another deep neural network, V2VNet, which
updates the 3D vector field with respect to the new sketches. All the three
networks are trained with synthetic data generated from a 3D hairstyle
database. We demonstrate the effectiveness and expressiveness of our tool using
a variety of hairstyles and also compare our method with prior art
3D hair sketching for real-time hair modeling and dynamic simulations
Ankara : The Department of Computer Engineering and the Institute of Engineering and Science of Bilkent University, 2008.Thesis (Master's) -- Bilkent University, 2008.Includes bibliographical references leaves 48-51.Hair has been an active research area in computer graphics society for over a
decade. Different approaches have been proposed for different aspects of hair
research such as modeling, simulating, animating and rendering. In this thesis,
we introduce a sketch-based tool making use of direct manipulation interfaces
to create hair models and furthermore simulate the created hair models under
physically based constraints in real-time. Throughout the thesis, the created tool
will be analyzed with respect to different aspects of the problem such as hair
modeling, hair simulation, hair sketching and hair rendering.Aras, RıfatM.S
3D hair design and key frame animation in real time
Ankara : The Department of Computer Engineering and the Institute of Engineering and Science of Bilkent University, 2008.Thesis (Master's) -- Bilkent University, 2008.Includes bibliographical references leaves 54-57.Computer generated animations of humans, animals and all other kinds of objects
have been studied extensively during the last two decades. The key for creating
good animations has been to correctly imitate the behaviors of real objects and
reflect these into computer generated images. With the rapid development of
computer technology, creating realistic simulations has become possible, and the
most striking components of these realistic animations happen to be the most
dynamic (moving) parts; hair, in the case of human animations.
With the development of high quality hair animations, the concern is not only
creating physically correct animations, but also controlling these animations. An
implementation of a key frame hair animation creation system, supported by a
hair design tool, helping to model and animate hair easily, and provide these
functionalities in real time is the aim of the proposed system.
This work reviews several hair animation and sketching techniques, and proposes
a system that provides a complete level of control (capable of controlling
even the individual hair strands) of key frame animation and hair design in real
time.Başarankut, BarkınM.S
