--- abstract: "The process of design and development of virtual environments can be supported by tools and frameworks, to save time in technical aspects and focusing on the content. In this paper we present an academic framework which provides several levels of abstraction to ease this work. It includes state-of-the-art components we devised or integrated adopting open-source solutions in order to face specific problems. Its architecture is modular and customizable, the code is open-source.\r\n" altloc: [] chapter: ~ commentary: ~ commref: ~ confdates: 2011 conference: 'INTETAIN ’11: 4th International ICST Conference on Intelligent Technologies for Interactive Entertainment' confloc: ~ contact_email: ~ creators_id: [] creators_name: - family: Catanese given: Salvatore honourific: '' lineage: '' - family: Ferrara given: Emilio honourific: '' lineage: '' - family: Fiumara given: Giacomo honourific: '' lineage: '' - family: Pagano given: Francesco honourific: '' lineage: '' date: 2011 date_type: published datestamp: 2011-10-27 01:34:39 department: ~ dir: disk0/00/00/76/65 edit_lock_since: ~ edit_lock_until: 0 edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 7665 fileinfo: application/pdf;http://cogprints.org/7665/1/cr%2Dcatanese%2Det%2Dal%2Dintetain11.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: ~ item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: ~ lastmod: 2011-10-27 01:34:39 latitude: ~ longitude: ~ metadata_visibility: show note: 'ISBN: 978-963-9799-58-5' number: ~ pagerange: ~ pubdom: TRUE publication: ~ publisher: ~ refereed: TRUE referencetext: ~ relation_type: [] relation_uri: [] reportno: ~ rev_number: 6 series: ~ source: ~ status_changed: 2011-10-27 01:34:39 subjects: - comp-sci-hci succeeds: 7647 suggestions: ~ sword_depositor: ~ sword_slug: ~ thesistype: ~ title: A Framework for Designing 3d Virtual Environments type: confpaper userid: 14714 volume: ~
