A web-based approach to image-based lighting using high dynamic range images and QuickTime object virtual reality
Abstract
This thesis presents a web-based approach to lighting three-dimensional
geometry in a virtual scene. The use of High Dynamic Range (HDR) images for the
lighting model makes it possible to convey a greater sense of photorealism than can be
provided with a conventional computer generated three-point lighting setup. The use of
QuickTime ™ Object Virtual Reality to display the three-dimensional geometry offers a
sophisticated user experience and a convenient method for viewing virtual objects over
the web. With this work, I generate original High Dynamic Range images for the
purpose of image-based lighting and use the QuickTime ™ Object Virtual Reality
framework to creatively alter the paradigm of object VR for use in object lighting. The
result is two scenarios: one that allows for the virtual manipulation of an object within a
lit scene, and another with the virtual manipulation of light around a static object. Future
work might include the animation of High Dynamic Range image-based lighting, with
emphasis on such features as depth of field and glare generation.
