Verto Studio runs on top of the most advanced editable graphics system on iOS. This document will help you wield that power and create amazing renderings and 3D artwork of your own. Let’s dive in and get started! About this document This document assumes the reader has a basic understanding of introductory 3D concepts such as cameras, polygons, vertices, normals, lighting and shading. Furthermore, experience in usage of 3D modeling software is beneficial, but not required in understanding this manual. The Scene Library Verto Studio 3D functions in one of two screens, the Scene Library and the Scene Editor. Within a moment of starting Verto Studio, you will be presented with the scene library screen. This screen allows you to organize and manage your various scenes, create a new blank scene, or import an OBJ file into a new scene. The library screen shows 2 scenes at once (or 1 in portrait orientation). Swipe left or right to navigate through your library. When you have more than a hand-full of scenes in your library, an option to switch to a grid display becomes available. Grid display allows you to see and browse through many documents at once on the screen screen for convenience. Each document contains a set of 3 document buttons. •The document button allows you to duplicate or rename a scene. •The send button allows you to export and share the scene as a Verto Studio file or an OBJ file. •The trash button will prompt you to remove a scene file. Importing OBJ files Verto Studio 3D comes with a built-in ability to import OBJ files as new documents. To ensure importing is successful, OBJ files should be generated with triangles and quads only (no edges). The file should also contain both normals, and texture coordinates. Additionally if applicable, MTL files and associated texture maps should be included as well. Once an OBJ file, MTL file, and textures are ready for import, open iTunes while your device is connected to your computer. Navigate to the apps tab and scroll down to "File Sharing" select "Verto Studio" from the list and drag in the associated files into the app's documents. After sync, the OBJ file will now be available for import. Alternatively, OBJ files may be opened from the Mail application from attachments within emails, from within dropbox, and from hyperlinks to OBJ files over the web. However, these method will not be able to load MTL files or textures like the aforementioned import method. The Scene Editor Overview The Scene Editor is where scenes may be viewed, explored, and of-course edited. It features a gesture-driven interface designed to be as simple and unobtrusive as possible. Most operations are supported through gestures performed within the auto tool, however precise tools and operations are available. During object mode,

If you have questions about how matrix math works and about how 3D rendering is done, you might want to use this chapter as a starting point and then go on and read a book such as Beginning Direct3D Game Programming,by Wolfgang Engel (Course PTR). The goal of this chapter is to provide you with a set of reusable functions that can be used to develop 3D games. Here is what you will learn in this chapter: ■ How to create and use vertices. ■ How to manipulate polygons. ■ How to create a textured polygon. ■ How to create a cube and rotate it. Introduction to 3D Programming It’s a foregone conclusion today that everyone has a 3D accelerated video card. Even the low-end budget video cards are equipped with a 3D graphics processing unit (GPU) that would be impressive were it not for all the competition in this market pushing out more and more polygons and new features every year.

  • 3D Modeling and the Role of 3D Modeling in Our Life
    ISSN 2413-1032 COMPUTER SCIENCE 3D MODELING AND THE ROLE OF 3D MODELING IN OUR LIFE 1Beknazarova Saida Safibullaevna 2Maxammadjonov Maxammadjon Alisher o’g’li 2Ibodullayev Sardor Nasriddin o’g’li 1Uzbekistan, Tashkent, Tashkent University of Informational Technologies, Senior Teacher 2Uzbekistan, Tashkent, Tashkent University of Informational Technologies, student Abstract. In 3D computer graphics, 3D modeling is the process of developing a mathematical representation of any three-dimensional surface of an object (either inanimate or living) via specialized software. The product is called a 3D model. It can be displayed as a two-dimensional image through a process called 3D rendering or used in a computer simulation of physical phenomena. The model can also be physically created using 3D printing devices. Models may be created automatically or manually. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D modeling software is a class of 3D computer graphics software used to produce 3D models. Individual programs of this class are called modeling applications or modelers. Key words: 3D, modeling, programming, unity, 3D programs. Nowadays 3D modeling impacts in every sphere of: computer programming, architecture and so on. Firstly, we will present basic information about 3D modeling. 3D models represent a physical body using a collection of points in 3D space, connected by various geometric entities such as triangles, lines, curved surfaces, etc. Being a collection of data (points and other information), 3D models can be created by hand, algorithmically (procedural modeling), or scanned. 3D models are widely used anywhere in 3D graphics.

Abstract—This paper introduces a novel method for simulating is that the simulation has to be good enough to test the decision underwater sonar sensors by vertex and fragment processing. making algorithms in the control system. The virtual scenario used is composed of the integration between When dealing with autonomous underwater vehicles the Gazebo simulator and the Robot Construction Kit (ROCK) framework. A 3-channel matrix with depth and intensity buffers (AUVs) a real-time simulation plays a key role. Since an AUV and angular distortion values is extracted from OpenSceneGraph can only scarcely communicate back via mostly unreliable 3D scene frames by shader rendering, and subsequently fused acoustic communication, the robot has to be able to make and processed to generate the synthetic sonar data.

  • An Evaluation Study of Preferences Between Combinations of 2D-Look Shading and Limited Animation in 3D Computer Animation
    Received May 1, 2015; Accepted October 5, 2015 An Evaluation Study of preferences between combinations of 2D-look shading and Limited Animation in 3D computer animation Matsuda,Tomoyo Kim, Daewoong Ishii, Tatsuro Kyushu University, Kyushu University, Kyushu University, Graduate school of Design Faculty of Design Faculty of Design [email protected] [email protected] [email protected] Abstract 3D computer animation has become popular all over the world, and different styles have emerged. However, 3D animation styles vary within Japan because of its 2D animation culture. There has been a trend to flatten 3D animation into 2D animation by using 2D-look shading and limited animation techniques to create 2D looking 3D computer animation to attract the Japanese audience. However, the effect of these flattening trends in the audience’s satisfaction is still unclear and no research has been done officially. Therefore, this research aims to evaluate how the combinations of the flattening techniques affect the audience’s preference and the sense of depth. Consequently, we categorized shadings and animation styles used to create 2D-look 3D animation, created sample movies, and finally evaluated each combination with Thurston’s method of paired comparisons. We categorized shadings into three types; 3D rendering with realistic shadow, 2D rendering with flat shadow and outline, and 2.5D rendering which is between 3D rendering and 2D rendering and has semi-realistic shadow and outline. We also prepared two different animations that have the same key frames; 24fps full animation and 12fps limited animation, and tested combinations of each of them for the evaluation experiment.
