Interactive 3D Architectural Modeling from Unordered Photo Collections
Photo Collections Architectural Modeling
2016/5/24
We present an interactive system for generating photorealistic, textured,
piecewise-planar 3D models of architectural structures and
urban scenes from unordered sets of photographs. To reconstruct

Automated Generation of Interactive 3D Exploded View Diagrams
exploded view illustration interactive visualization
2016/5/24
We present a system for creating and viewing interactive exploded
views of complex 3D models. In our approach, a 3D input model
is organized into an explosion graph that encodes how parts explode
w...
We present techniques for automatically parsing existing sewing
patterns and converting them into 3D garment models. Our parser
takes a sewing pattern in PDF format as input and starts by extracting...
3D Puppetry: A Kinect-based Interface for 3D Animation
Tangible user interface animation object tracking
2016/5/24
We present a system for producing 3D animations using physical
objects (i.e., puppets) as input. Puppeteers can load 3D
models of familiar rigid objects, including toys, into our system
and use the...
MotionMontage: A System to Annotate and Composite Motion Takes for 3D Animations
Active visual feedback Depth camera Animation Montage
2016/5/24
We present MotionMontage, a system for recording multiple
motion takes of a rigid virtual object and compositing
them together into a montage. Our system incorporates a
Kinect-based performance cap...
History Assisted View Authoring for 3D Models
3D model editing history viewpoint authoring
2016/5/24
3D modelers often wish to showcase their models for
sharing or review purposes. This may consist of generating
static viewpoints of the model or authoring animated flythroughs.
Manually creating su...

Various urban models have been developed and are used in the urban domain, to perform for example air quality calculation,
building energy consumption analysis or traffic simulation. The use of urban...
3D打印中的模型分割与打包
3D打印 模型分割 打包算法 禁忌搜索
2016/7/28
为了提高3D打印技术中三维模型的打印效率，减少打印材料耗费，缩短打印时间，提出了一种全局最优的模型分割与打包算法。首先，将给定模型分割为若干金字塔形状的分块。然后利用一种改进的禁忌搜索算法寻找最优打包方案，尽可能地减少支撑材料的体积，根据分块体积给出利于全局优化的初始解，并通过控制邻域生成规则以及候选解集，使得搜索更加高效并大幅提高寻优速度。最后，将打印成型的各部件拼合成整体。实验结果表明：生成的...

The experience that I want to present consists of the case of piazza Bodoni in Turin, characterized, between 1866 and 1924 by the presence of an original pavilion dedicated to market.
3D碳纳米管计算机芯片问世（图）
3D碳纳米管 计算机芯片
2015/9/22
美国研究人员表示，他们使用碳纳米管替代硅为原料，让存储器和处理器采用三维方式堆叠在一起，降低了数据在两者之间的时间，从而大幅提高了计算机芯片的处理速度，运用此方法研制出的3D芯片的运行速度有可能达到目前芯片的1000倍。研究人员之一、斯坦福大学电子工程学博士候选人马克斯·夏拉克尔解释道，阻碍计算机运行速度的“拦路虎”在于，数据在处理器和存储器之间来回切换耗费了大量的时间和能量。然而，解决这个问题非...
