Abstract
The paper proposes the utilization and application of 3D Game Engine technology that prevails in computer games i.e. the First Person Shooter game genre, into developing a low cost and high performance real world Walkthrough Virtual Reality (VR) prototype application. This technique is proposed as a solution to the limitation of the widely used low cost VR technologies namely Virtual Reality Modelling Language (VRML) and 360° Panoramic View (based on Apple QuickTime VR).
