Аннотация Use of VR technologies (virtual reality technologies) or their partial application allow to create and manage with photo-realistic design, 3D-interface, 3D sound, 3D models and scenes, 3D Internet pages and other VR-based objects. VR technologies are generally implemented in games, simulators, and 3D museums/galleries today. The methods of its application are different and depend on the product’s area of application, desired effect and end-of-user hardware capabilities. Owing to the last factor and difficulty of application VR technologies aren’t widespread among multimedia developers. However, it can be applied to any multimedia project designed for common average computers and devices to a greater or lesser extent. The following topics are covered in this publication: rendering methods of 3D models and scenes; Intel and AMD processor commands (MMX, SSE, SSE2, 3DNow!); features and differences between graphics libraries OpenGL and DirectX; use of DirectSound and Aureal A3D Interactive SDK for 3D sound transmission, idea of HRTF. Capabilities of Creative EAX were described. Software tools were suggested for creation and application of VR and multimedia content.
