ABSTRACT

This work presents results of educational videos development, mono or stereo, for scientific

dissemination of nuclear energy applications. Nuclear energy span through many important applications

for the society, ranging from electrical power generation to nuclear medicine, among others. Thus, the

purpose is to disseminate this information for the general public and specially for students. Educational

videos consist in a good approach for this purpose, due to the involvement of the public they provide,

more than simply text or oral exposition, or even static images presentation. Stereo videos result in even

more involvement of the public, besides immersion, the later due to the realism 3D views provide. The

video developed in this work deals with explanations of electrical power generation, including nuclear

reactor operation, shows the percentage of nuclear source as power generation all over the world, and

explains also nuclear energy application in medicine. It is expected all these characteristics provided by

the use of video or virtual reality techniques will achieve the purpose of disseminating such important

information, regarding the benefits of nuclear energy to the society.

1. INTRODUCTION

The energy generated by nuclear source is part of trie reality of many countries, bringing

with it many benefits for society, however, often not being recognized for his

accomplishments, in general, much of the public sees with great prejudice. So this work

is to involve Virtual Reality (VR) technologies in the teaching process in order to

provide a motivating learning and dissemination of the concepts that supports nuclear

power to society. More specifically, the work aims to disseminate widely and

motivating greater information about what is nuclear energy and some of its

applications, seeking in this way break the existing bias and show their benefits, through

the dissemination of its activities, through videos created at Laboratorio de Realidade

Virtual (LABRV)- IEN/CNEN, in order to promote the involvement of the public.

Virtual Reality is the use of high-tech systems and integration with aim to convince the

user that he is in another reality, thereby, a bigger immersion [1].

This information will be transmitted differently involving the use of Virtual reality as a

learning tool, through educational videos focused on showing the operation of a nuclear

power plant, its application in medicine, such as nuclear energy becomes electric and

thermal energy as nuclear power plants are distributed worldwide. The videos

developed in mono and stereo, will thus, experiments with knowledge so immersive and

interactive to be presented in supportive environments for this type of visualization. The

LABRV has a favourable infrastructure to meet your audience has a stereo projection

room of 13 seats, a passive projection screen ( 2 x 3 m), as well as walls painted black,

which gives the user an immersive experience [2].

Virtual Reality expands the normal processes of learning, where the learner is

encouraged to particípate in a creative and fun process, exploring subjects in traditional

methods would take longer to be taught [3]. Virtual Reality provides a greater

involvement and motivation of the students, thus increasing the productivity of the

target audience. VR allows the illustration of some processes and objects, promotes an

analysis of reality viewed from different angles and allows viewing and exploring

places non-existent or difficult to access [4].

2. METHODOLOGY

Techniques of computer graphics and modeling of environments were used along the

three applications essential for the composition of the video, both in mono and your

versión in stereo. The stereoscopy is related to the ability to see in three dimensions, i.e.

to perceive depth. The working principie of most devices stereoscopic is offering

distinct images left and right eyes of the observer, providing a sensation of depth, such

as when observing a real object. [5]

3ds Max software, Sony Vegas Pro 10.0 and Adobe After Effects, used in this project

are described below in the topics below.

2.1. 3ds Max

The first program to be described will be 3ds Max, in which its developer is Autodesk,

and the versión used for the completion of the work was the 2011. 3ds Max, is a

modeling software in three dimensions that offers powerful integrated features of

modeling, animation, rendering and 3D composition that enable artists and designers to

increase your productivity with speed [6]. The program is used in the production of

animation films, camera rides, creation of 3D game characters and commercials for TV

and on creating virtual environments. The files generated by 3ds Max have the native

extension.MAX. However is extremely compatible with many three-dimensional

modeling software. This program has some methods for polygonal modeling, Edit: Edit

Poly Mesh and NURBS. When need some modifiers may be used for predictive

modeling objects.

The modeling method used for the creation of the video was the Editable Poly. This

type of modeling is made primarily of polygons created individually and in sequence,

for this reason, also called poly by poly or Box modelling, which consists of creating a

standard primitive (Cilinder, Tube, Box, Sphere, etc.) or an extended Primitives

(Chamfer, Oil Tank and etc).

The software allows the generation of high-quality renderings, with one or more lamps

photometric or omni, shadows, transparency, translucéncia, reflections, refractions. Sub-

Surface-Scattering, among others. The program comes with the Default Render Scanline

and MentalRay renderers which are included, the latter being one of the most complete

existing. With the rendering is possible to créate photorealistic images, simulating

environments, internal and external scenarios. The more detail and better for the user-

defined setting in scene, more time will be the rendering process.

3ds Max (Figure 1) is considered one of the leading proprietary software for generating

animated scenes in computer (CGI). The program includes tools cream that allow

physically realistic animations by simulating gravity, collisions and explosions. The

software allows the use of plug-ins directly. For the scenes with stereographic was used

the plug-in XidMary written by HabWare. This plug-in which can be found at various

sites to download [7], allows you to feel 3D using glasses. The plug-in creates a dual

camera where each one represents an eye. This plug-in can be used perfectly with the

Mental Ray renderer.

2.2 Sony Vegas Pro 10.0

The next program to be described will be Sony Vegas Pro 10.0 (Figure 2), its a

SonyCreative Software Developer, for the project were used the latest versión, 10.0 Pro.

The Sony Vegas Pro is a Sony software that renders in almost all formats, and also

capable of producing material in high definition. The program offers non-destructive

editing, that is, files are handled without changing the contents of their sources. The

Sony Vegas video editing combines high quality real-time in any proportion (4: 3, 16: 9,

etc.) or pixel under numerous rates of frames per second. Includes a set of effective

tools for audio that meets the needs of most demanding productions. Applies the

overlapping audio track automatically and smoothly.

The programme Vegas Pro 10 includes video effects and transitions that improves the

quality of the film. All video effects can be animated by setting where is its beginning

and end. The software allows the effects and transitions are seen in real time [8].

In this project the scenes were written individually through the following images, for

which then were joined. In some taken there was a need to increase or cut portions of

the scene, for a better development of the video. For the rendering of the movie we use

59 frames per second, with the goal of having a more fluid animation. The speeches

recorded within the LABRV and the music were edited and placed on two tracks of

audio.

Figure 2 - shows the programme Sony Vegas Pro 10.0 the customized interface for

audio and video editing.

2.3. Adobe After Effects The last program to be described will be Adobe After Effects, it is used to compose

videos previously generated in 3ds Max. How it works: the 3ds Max genérates a

sequence of frames (or images) and After Effects makes the join them which results in a

video in AVI format.

After Effects includes a variety of effects, with goal to add or modify the features of

static images, video and audio. For example, an effect can alter the exposure or color of

an image, add new Visual elements, manipúlate sound, distort images, remove grain,

improve lighting, or créate a transition [9].

In addition to the junction of the frames, we use the program for the creation of the

opening scenes of the presentation of themes and for completion of the video.

After Effects (Figure 3) uses animation using keyframes, which are points that créate

and control animation as follows: a keyframe created has information on speed, type of

movement (rotation, scaling, etc) and information about the points immediately

following and preceding it. Example: when a keyframe is created in After Effects, its

possible give the software all the information about that time in animation; the exact

location of the element on the screen, its scale, if you're moving or not and etc [10].
