Geometric restoration that composes 3D fragmented pieces into the original complete object is an important computer graphics and geometric processing problem. Automatic and effective restoration has applications in many fields such as archeological ...

Sketching is a natural human practice. With the popularity of multi-touch tablets and styluses, sketching has become a more popular means of human-computer interaction. However, accurately recognizing sketches is rather challenging, especially when they ...

Unsupervised matting, whose goal is to extract interesting foreground components from arbitrary and natural background regions without any additional information of the contents of the corresponding scenes, plays an important role in many computer ...

Realistic representation of nature scenes is one of the most challenging areas in computer graphics community. There are important factors to synthesize realistic scenes in 3D CG which are decayed materials such as dead trees, weathered statues, rusty ...

3D printing is becoming a more common technology and has a growing number of applications. Although 3D compression algorithms have been studied in the computer graphics (CG) community for decades, the quality of the compressed 3D models are discussed ...

During a snowfall, the snow crystals accumulate on the ground and gradually form a complex porous medium constituted of air, water vapour, ice and sometimes liquid water. This ground-lying snow transforms with time, depending on the physical parameters ...

Exploring various visual designs by tweaking parameters is a common practice when designing digital content. For example, if we want to clean up a photo for use at the top of a web page, we adjust the design parameters---brightness, contrast, saturation,...

In this work, we present some of the unexpected observations resulted from our recent research. We, recently, needed to identify a small number of important critical points, i.e. minimum, maximum and saddle points, on a given manifold mesh surface. All ...

In this work, we present a simple mathematical approach to art directed shader development. We have tested this approach over two semesters in an introductory level graduate rendering & shading class at Texas A&M University. The students in the class ...

Maintaining a high steady frame rate is an important aspect in interactive real-time graphics. It is mainly influenced by the number of objects and the number of lights to be processed for a 3d scene. The upper-bound effort for rendering a scene is then ...

In freeform architecture and fabrication aware design, repetitive geometry is a very important contribution to the reduction of production costs. This poster addresses two closely related geometric rationalizations of freeform surfaces with repetitive ...

Computer graphics applications require models which are crafted by hand, requiring skill and time. In architectural applications an automated system that converts 2D floor plan images into 3D building models can be used to lower the modeling cost, and ...

Keyboard percussion instruments such as xylophones and glockenspiels are composed of an arrangement of bars. These are varied in some of their geometrical properties---typically the length---in order to influence their acoustic behavior. Most ...

[Hong et al. 2008] proposed a hybrid method of Eulerian grids and Lagrangian particles to represent small-scale bubbles in large-scale water. In the simulation, bubbles rise freely in the water; however, bubble seeds are set at random at the bottom and ...

We solve the form-finding problem for polyhedral meshes in a way which combines form, function and fabrication; taking care of user-specified constraints like boundary interpolation, planarity of faces, statics, panel size and shape, enclosed volume, ...
