Model Of Software Development Process For Virtual Environment –A Case Study - Shraddha Pathak

Introduction  Software Development Process  Virtual Environment  Software Used for developing virtual environment

Virtual Environment  What is environment?  What is virtual environment?  Characteristics of virtual environment  Synthetic  Tri-dimensional  Multi-Sensory  Immersive  Interactive  Realistic and with presence

Case Study  Why development process?  Chosen virtual environment -Historical museum  Chosen Software tools - WTK

Model of Software Development Process  Requirements Definition - Definition of the users - Definition of standard requirements for virtual environment - Definition of requirements for the application

Model of Software Development Process  Design Phase  Input Technology keyboard, mouse, HMD, gloves  Output technology visual displays, headphone speakers, tactile arrays

Design Phase  Hardware technology - Initially Pc Pentium platform with windows operating system - Finally workstation silicon graphics Indigo2 with IRIX 6.2 operating system  Software technology - WTK (WorldToolKit by Sense8)

Design Phase  Design of Objects, behavior, interaction - Colors, forms textures applied to objects that reproduce original ones - Behavior of objects like opening & closing the door, turning lights on and off - Interaction between user and system with walkthrough architecture

Implementation  Gathering and preparation of images  Construction of 3D objects  Execution of virtual environment  Additional Implementation aspects

Evaluation  Informal way  Mainly referred usability aspects  Iterative redefined the system

Implementation Aspects  Multiple views

Implementation Aspects  Multimedia  Zoom

Implementation Aspects  Easy Visualization  Animation

Conclusion Purely iterative process Incorporate all necessary features for virtual reality application Immersive aspect implemented by walkthrough Made interactive by menus, zooms, animations
