introduction: excessive temperature rise during drilling of the mandible for dental implant placement might damage adjacent osseous tissues. various factors affect temperature rise, including the geometrical parameters of surgical drills, one of which is the drill bit head angle. the aim of this research was to determine suitable drill bit head angle to induce minimum temperature rise during ma...

This article presents the results of heat-treated low-alloy steel microstructure research using Deform 3D program, which allows determining optimal technological parameters hardening. The object is pipe grade 12CrMoV. To determine and evaluate heat treatment affecting increase in mechanical properties, modeling specified program were used. compare results, we used method for properties during t...

In a Collaborative modelling environment, multiple users may interact in a virtual environment to deform or modify shared 3D objects (e.g., for modelling and visualization of virtual prototypes). The challenges to collaborative modelling are related mainly to four aspects: user interaction with the virtual modelling environment, 3D objects concurrent editing, consistency maintenance among clien...

Thin-walled aluminium parts are employed in a variety of industries, including construction and aerospace. If they treated to greater quantity milling, more resistant deformation. As result, the stability work degrades, surface roughness increases as result this factor. This proposes use well-designed fixture with support heads lessen deformation produced by square thin-walled plate milling. Th...

We propose a new stereo matching algorithm which computes the depth and surface orientation simultaneously. While area-based stereo matching is an essential technique in the recovery of the dense 3D shape, conventionally it uses square windows based on the implicit assumption that intensity patterns surrounding corresponding points have no deformations between images from different views. In pr...

In this paper, we present a novel system for facilitating the creation of stylized view-dependent 3D animation. Our system harnesses the skill and intuition of a traditionally trained animator by providing a convivial sketch based 2D to 3D interface. A base mesh model of the character can be modified to match closely to an input sketch, with minimal user interaction. To do this, we recover the ...
