Three different systems are disclosed for producing data bases that are used to drive virtual reality display apparatus. The systems employ 3-D stereo camera pairs, airborne microphones, conduction microphones, physical and chemical sensors, CPU's and supporting electronics. The data bases can be used by virtual reality audiences in real time as the data bases are created or they can be stored and used at a later time. The systems are dedicated to eliminating artifacts that would otherwise tend to interfere with the enjoyment of the virtual reality experience for virtual reality viewing audiences. The systems cover multidimensional video content, multidimensional audio content, multidimensional physical content and multidimensional chemical content. The systems are intended to be set up inside a venue for capturing VR content.
