Abstract:
This article presents a new educational approach to teaching the discipline of stereometry by creating a 3D application working in virtual reality (VR) with and without immersion. The application is developed using Java3D. A new algorithm that uses elements of Cavalieri’s method of indivisibles and Isaac Newton’s method of limits is applied to generate regular polygon-based geometric figures, such as prisms and pyramids. A traditional method using trigonometry and 2D/3D graphics extrusion generates geometric shapes such as cone, cylinder and torus. The application interface uses 2D techniques,

Abstract:
StereoMV is a part of а dissertation on a topic "Stereoscopic Training System". The main purpose of the stereo system is to facilitate learning of the concepts of stereometry. The system is the author’s and offers a new approach for generating geometric bodies. The boundary method is used for creating the figures, which is based on the method of the boundaries of Isaac Newton and the "Indivisible" of the Italian mathematician Bonaventura Cavalieri. The study shows how by using 3D technologies such as virtual reality and 3D printing, the process of teaching in stereometry classes will be signif

The kinematic center (KC)—defined by coinciding jaw-opening/-closing and protrusion-retrusion trajectories—has been proposed in the literature as a reference point to represent TMJ movements. In this study, we tested whether the KC lies in a peculiar anatomical point and whether its trajectory reflects intra-articular distance. In 11 asymptomatic individuals (seven females, four males, aged 24–37 yrs), 4 openings/closings and 4 protrusions/retrusions were tracked with dynamic stereometry. In a 3D lattice (0.5 mm grid) constructed solidly around each condyle, the KC was the point with maximal c

In stereometry, the technique of three dimensional SEM imaging is fairly straightforward. Selected specimen area is photographed using SEM imaging tools from two different angles. Tilting is performed using standard SEM manipulation tools. In some cases, the specimen must be rotated to such a position, in which the tilting is done on visua
