360° - Technology of Virtual Tour

360.png, 67kB

The first step required to create a virtual tour is to capture the virtual tour images. Virtual tour images are created by capturing a 360 degree image from the center point of view of the scene. This is done by placing a specially equipped digital or film camera on a panoramic tripod head at the center point of the scene and rotating the camera as the image is captured.

Post Capture Image Processing and Retouching

The second step required to create a virtual tour is to process and retouch your captured images. This involves the stitching together, and retouching of separate images captured in sequence with a still camera.

Preparation For Web or CD-ROM Deployment

The final step required to create a virtual tour is to prepare the virtual tour for deployment on the Web or CD-ROM. Virtual tours can be deployed using plug-in (Flash, DEVAL) or Java technologies. A plug-in is a helper application which works within a Web browser, or as a stand alone application. The advantage of plug-ins is that they extend and improve a browser's capability.

HDRI

High dynamic range imaging (HDRI or just HDR) is a set of techniques that allows a greater dynamic range of luminances between light and dark areas of a scene than normal digital imaging techniques. The intention of HDRI is to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to shadows.
