The problem human face shape reconstruction basing on information about human skull is very important for many applications beginning with archeology and finishing with crime expertise. World recognition was received with a face shape reconstruction technique proposed by M. Gerasimov [1]. This method up to now is the general method for face reconstruction of unknown person. It operates with the...

Texture is an essential property of physical objects that affects aesthetics, usability, and functionality. However, designing and applying textures to 3D objects with existing tools remains difficult and time-consuming; it requires proficient 3D modeling skills. To address this, we investigated an auto-completion approach for efficient texture creation that automates the tedious, repetitive pr...

In computer vision we often estimate a 3D model of an object, and its uncertainty, up to an unknown scale factor. This unknown scale factor means that we cannot directly infer positions and lengths on the model, nor their uncertainties. In order to make quantitative distance measurements on this model, we must obtain the unknown scale factor. However, how we determine the scale factor will affe...

We present a technique for rendering animated 3D models in a Su-Muk painting style with user’s guide. First, a user can sketch directly over 3D models by varying ink and water values. And we simulate the behavior of ink-water directly on 3D model for consistent shade information over 3D models. After simulation, ink and water are spread over a 3D surface appropriately. Second, to achieve a real...

In recent years, with the improvement of computer processing power and the development of sophisticated visualisation software, the traditional static views of geological maps, cross-sections, and other analogue representations have been replaced by digital, three dimensional (3D) models. Building these 3D models involves the assembly of many previously isolated and disparate datasets into a si...

Texturing gives a new quality to a 3D model making it more similar to real object and more adequate for human perception and understanding. Recent progress in means for spatial data acquisition and in 3D reconstruction techniques creates a background for metric 3D models generation, which could be successfully used instead of a real object for purposes of various investigations dealing with geo...

We live in a 3D world, performing activities and interacting with objects in the indoor environments everyday. Indoor scenes are the most familiar and essential environments in everyone’s life. In the virtual world, 3D indoor scenes are also ubiquitous in 3D games and interior design. With the fast development of VR/AR devices and the emerging applications, the demand of realistic 3D indoor sce...

Background and Aim: Bone density is of great assistance in the selection of the proper implant site. The present study aimed to assess the correlation between tissue densities in computed tomography (CT) and three different cone-beam computed tomography (CBCT) units. Materials and Methods: In this descriptive study, a radiographic phantom consisting of a transparent polymethyl methacrylate (PM...

The emergence of inexpensive and flexible 3D digitization tools and technologies and of increasingly easy to use and intuitive 3D editing software, as well as affordable and accessible 3D printing, has lowered the bar for creative engagement with the museum through digital 3D activities. Museums are increasingly making 3D models from their collections available online 1 and a vast number of 3D ...
