Conveying Shape and Features with Image-Based Relighting
Visualization Relighting Image Composition Scientfic Illustration Technical Illustration Photography Lighting Design
2016/5/24
Hand-crafted illustrations are often more effective than photographs
for conveying the shape and important features of an object, but
they require expertise and time to produce. We describe an image...
A Sketching Interface for Articulated Figure Animation
Figure Animation Sketching Interface
2016/5/24
We introduce a new interface for rapidly creating 3D articulated figure animation, from 2D sketches of the
character in the desired key frame poses. Since the exact 3D animation corresponding to a se...
Efficient Image-Based Methods for Rendering Soft Shadows
Shadows Raytracing Image-Based Rendering
2016/5/24
We present two efficient image-based approaches for computation
and display of high-quality soft shadows from area light sources.
Our methods are related to shadow maps and provide the associated
b...
In composing hand-drawn images of 3D scenes, artists often alter the projection for each object
in the scene independently, thereby generating multiprojection images. We present a tool for
creating ...
A Design and Implementation for Effective Computer-Generated Route Maps
Design and Implementation Computer-Generated Route Maps
2016/5/24
A route map depicting a path from one location to another
is a powerful tool for visualizing and communicating directions.
However, it can be difficult for a computer to automatically
render route ...
DIZI: A Digital Ink Zooming Interface for Document Annotation
Document Annotatio Zooming Interface
2016/5/24
Pen computing devices provide a natural interface for annotating
documents with freeform digital ink. However, digital ink annotations are usually
larger and sloppier than real ink annotations on pa...
Piecewise Image Registration in the Presence of Multiple Large Motions
Registration Large Motions
2016/5/24
We present a technique for computing a dense pixel correspondence
between two images of a scene containing multiple
large, rigid motions. We model each motion with either
a homography (for planar o...
Phrasing Techniques for Multi-Stroke Selection Gestures
phrasing tablets gestures pen input multiple strokes
2016/5/24
Pen gesture interfaces have difficulty supporting arbitrary
multiple-stroke selections because lifting the pen introduces
ambiguity as to whether the next stroke should add to the existing
selectio...
Tumble! Splat! Helping Users Access and Manipulate Occluded Content in 2D Drawings
Layer management 2D drawing occlusion interaction technique
2016/5/24
Accessing and manipulating occluded content in layered 2D drawings
can be difficult. This paper characterizes a design space of
techniques that facilitate access to occluded content. In addition,
w...
Hover Widgets: Using the Tracking State to Extend the Capabilities of Pen-Operated Devices
Hover Widgets pen input gestures tablets
2016/5/24
We present Hover Widgets, a new technique for increasing
the capabilities of pen-based interfaces. Hover Widgets are
implemented by using the pen movements above the
display surface, in the trackin...
Gaze-Based Interaction for Semi-Automatic Photo Cropping
cropping photography composition evaluation eye tracking, visual perception
2016/5/24
We present an interactive method for cropping photographs
given minimal information about the location of important
content, provided by eye tracking. Cropping is formulated in
a general optimizati...
Zone and Polygon Menus: Using Relative Position to Increase the Breadth of Multi-Stroke Marking Menus
Marking menus pie menus positionbased menus pen-based interfaces
2016/5/24
We present Zone and Polygon menus, two new variants of
multi-stroke marking menus that consider both the relative
position and orientation of strokes. Our menus are designed
to increase menu breadt...
This paper addresses the problem of efficiently calculating shadows from environment maps
in the context of ray-tracing. Since accurate rendering of shadows from environment maps
requires hundreds o...
Interactive Cutaway Illustrations of Complex 3D Models

2016/5/24
We present a system for authoring and viewing interactive cutaway
illustrations of complex 3D models using conventions of traditional
scientific and technical illustration. Our approach is based on ...
We present an interactive texture painting system that allows the user to author digital images by painting with
a palette of input textures. At the core of our system is an interactive texture synth...
