We present results of using Bayesian inference for recovering the 3-D shape and texture of an object based on information extracted from a single 2-D image. We are using a number of different models for specific object classes. The goal is to combine the classes to a hierarchical structure. Instead of searching for the most probable explanation we estimate the entire posterior distribution of t...

This paper possesses information about the Creation of Rendering 3D Haptic Shapes in MidAir Using Ultrasound. Today’s haptic Technology is all around us & changed rapidly over the last few years with touch feedback & used in entertainment, rehabilitation and even surgical training. The buzz of your smartphone as you tap the keys, or the rumble of your Wii controller as you smash a tennis ball a...

The task of 3D shape classification is to assign a set of unordered shapes into pre-tagged classes with class labels, and find the most suitable class for a newly given shape. In this paper, we present a 3D shape classifier approach based on supervision of the learning of point spatial distributions. In this classifier, we first extract the low-level features by characterizing the point spatial...

Analytical solutions are presented for laminar fully developed flow in micro-/ minichannels of hyperelliptical and regular polygonal cross sections in the form of compact relationships. The considered geometries cover a wide range of common simply connected shapes including circle, ellipse, rectangle, rectangle-with-round-corners, rhombus, star-shape, equilateral triangle, square, pentagon, and...

In recent years, 3D sketching has gained popularity as an efficient alternative to conventional 3D geometric modeling for rapid prototyping, as it allows the user to intuitively generate a large range of different shapes. In this paper, we present some sketching interactions for 3D modeling, based on a set of two different bidimensional sketches (profile curve and silhouette curve). By using th...

This paper presents a sketching system for 3D organic shapes modeling and animation using virtual reality devices. On the hardware side, it is based on the Haptic WorkstationTM which conveys force feedback on the user arms (upper body limbs), and a Head Mounted Display to present the 3D generated images. On the software side, we use implicit surfaces modelling techniques such as metaballs. In f...

We present a single generalized method for computing skeletons for arbitrary objects in both 2D and 3D space. We also present a method for computing the multiscale boundary-collapse importance metric for arbitrary 2D shapes in an incremental fashion, the results of which are comparable to the AFMM Star for 2D shapes. Finally, we reveal an approach which potentially allows the same importance me...
