  • Unit 31: Computer Animation
    Unit 31: Computer Animation Unit code: D/601/7658 QCF Level 3: BTEC National Credit value: 10 Guided learning hours: 60 Aim and purpose The aim of this unit is to ensure learners understand types of animation and their uses and develop the knowledge and skills required to use software techniques to design and implement different types of animation. Unit introduction Computer animation is the art of creating moving images through the use of computers. It brings together computer graphics and animation techniques. Animation does not require computers, however the increasing ability of computers to create and manipulate sets of images has allowed basic animation to reach new levels of sophistication and realism. To create the illusion of movement, a sequence of images is displayed over time and the human eye perceives this sequence as continual movement. The technique is at the heart of all existing technologies such as television and motion pictures. It is increasingly created by means of 3D computer graphics, although 2D computer graphics are still widely used for low bandwidth and faster real-time needs. Only 2D graphics are required in this unit. Animation has become a prominent feature of the worldwide web and is used to create interest and attract attention. In this area, however, there are other factors that need to be taken into account when designing and building applications, such as the nature of the display device and the bandwidth of the connection. As with all computer applications learners must first identify the need, specific requirements and constraints before building the solution. Learners will start by looking at different types of animation and their uses and formats.

  • Jack's Poser Pro Manual Last Update: 2021 09 17
    Jack's Poser Pro Manual Last Update: 2021 09 17 Note 1: This Manual has been prepared for my own use. If you find it useful, great. However, don't be surprised (or angry with me) if I have failed to update something that has changed from one version of Poser to the next and which I haven't discovered yet. Or if I have failed to understand and so incorrectly describe something. If I discover (or have pointed out to me) that something in this Manual doesn't work as I described, I'll see about updating my text. Note 2: I installed Poser 12 on 30 November 2020. I have no idea if anything in this Manual has changed in Poser 12. I will make necessary changes as I find them. I began using Poser Pro 2012 on about 2013 01 07. This file was started soon after doing a bit of experimenting and finding that I had no tutorial. So here are the results from experimenting, reading Poser Pro 2012 Reference Manual, Poser Pro 2014 Reference Manual, Poser Pro 11 Reference Manual, Smith Micro Tech Support, and internet research. I also have Practical Poser 8. The Official Guide, by Richard Schrand, even though Poser 8 would seem to be several iterations behind Poser Pro 2014, and even farther behind Poser Pro 11 which I started using in December 2015, or Poser 12 as noted above. Most of the information in this Manual is based on my experiences with Poser Pro 2012 and 2014, and probably still holds true for Poser Pro 11 or Poser 12 versions.

  • Aplikasi Untuk Desain Grafis Yang Gratis
    Aplikasi Untuk Desain Grafis Yang Gratis Faisal Aditya [email protected] Abstrak Bagi animator maupun yang suka bergelut di bidang desain grafis software berbasis 3D adalah fondasi utama dalam merancang sebuah desain sehingga menghasilkan nilai seni yang tinggi dan kepuasan tersendiri. Namun software yang digunakan terbilang cukup berat dari segi biaya maupun kapasitasnya. Disini saya akan memaparkan aplikasi yang gratis agar tidak memakan biaya bagi anda dan juga bisa untuk belajar. Kata Kunci : aplikasi, desain grafis,free, komputer Pendahuluan Desain grafis adalah bagian penting dari sebuah lapangan pekerjaan yang sifatnya seni modern. Contohnya dalam perfilman, jika tidak ada software desain grafis maka pencitraan karya yang dibuat kurang menarik bahkan tidak menarik untuk dinikmati penikmat film karena sentuhan akan modernisasi kurang memukau dan juga sebagai alasan memadukan unsur fisik (nyata) dan rekayasa. Maka haruslah ada software/aplikasi yang mendukung.

Meskipun begitu tidak berarti grafis Tiga dimensi (3D) mudah dibuat. Untuk membuat grafis Tiga dimensi, maka harus dibuat dalam alat authoring 3D yang biasanya memerlukan biaya yang cukup besar untuk pengguna yang bukan profesional dibidang ini. Sebuah model 3D biasanya dibuat menggunakan alat pemodelan 3d. Oleh karena itu, saya pikir mungkin menarik untuk membahas ketersediaan sumber alat pemodelan 3D yang gratisan.

  • An Overview of 3D Data Content, File Formats and Viewers
    Technical Report: isda08-002 Image Spatial Data Analysis Group National Center for Supercomputing Applications 1205 W Clark, Urbana, IL 61801 An Overview of 3D Data Content, File Formats and Viewers Kenton McHenry and Peter Bajcsy National Center for Supercomputing Applications University of Illinois at Urbana-Champaign, Urbana, IL {mchenry,pbajcsy}@ncsa.uiuc.edu October 31, 2008 Abstract This report presents an overview of 3D data content, 3D file formats and 3D viewers. It attempts to enumerate the past and current file formats used for storing 3D data and several software packages for viewing 3D data. The report also provides more specific details on a subset of file formats, as well as several pointers to existing 3D data sets. This overview serves as a foundation for understanding the information loss introduced by 3D file format conversions with many of the software packages designed for viewing and converting 3D data files. 1 Introduction 3D data represents information in several applications, such as medicine, structural engineering, the automobile industry, and architecture, the military, cultural heritage, and so on [6]. There is a gamut of problems related to 3D data acquisition, representation, storage, retrieval, comparison and rendering due to the lack of standard definitions of 3D data content, data structures in memory and file formats on disk, as well as rendering implementations. We performed an overview of 3D data content, file formats and viewers in order to build a foundation for understanding the information loss introduced by 3D file format conversions with many of the software packages designed for viewing and converting 3D files.
