Lecture ContentBrief introduction to the simulation process VR Technologies and interfacesBenefits of utilising VR in connection with simulation processes. Cases and examples from research projects, including Business Process issues.

Simulation processes: an introductionSimulation is about process modeling (digitally or physical) of a real world/system and examine its performance under a wide range of variables.In this lecture we are concerned with digital simulation where computer models are used to mimic real situation and examined under different situations.

Building & Construction simulation processesWhat are the building processes that we are trying to simulate:Simulation of construction sites layoutsSimulation of construction equipments working togetherSimulation of production lines and construction schedules.

Simulations Collections of objects (cells) that are modeled and connected to form a particular system (for example: no of units in which a particular machine can process per time, etc)

Simulation techniquesHow we build modelsEvent oriented simulation (can be through user interaction)Time oriented simulationa mixture of the above.

Interfacing with simulation modelsIs the ability of the simulation model to accept instructions (inputs) for users while the simulation process is in progress.

Virtual RealityWhat is a VRVR is the simulation of a real or imagined environment that can be experienced visually in three dimensions and that may additionally provide an interactive experience visually in full real-time motion with sound, etc..

VRMLVirtual Reality Modeling Language, is the standard for the web and allows the creator to specify images and rules for their display and interaction using textual language statements.It's a scene description language that describes the geometry and behavior of a 3D scene or "world".

VRML FeaturesStandard objects (cube, sphere, cone, cylinder, text) Arbitrary objects (surfaces, linesets, pointsets) Ability to fly through, walk through, examine scenes Lights Cameras (viewpoints) Textures on objects Clickable links Define and reuse objects

VRML FeaturesAnimated objects Switches Sensors Scripts (Java or JavaScript) for behaviors Interpolators (color, position, orientation, etc.) Extrusions Background colors and textures Sound (.wav and MIDI) Animated textures

VRML StructureVRML worlds(single or group that load at the same time)They can range from simple objects to very complex scenes
