A web-based approach to image-based lighting using high dynamic range images and QuickTime object virtual reality

摘要

This thesis presents a web-based approach to lighting three-dimensionalgeometry in a virtual scene. The use of High Dynamic Range (HDR) images for thelighting model makes it possible to convey a greater sense of photorealism than can beprovided with a conventional computer generated three-point lighting setup. The use ofQuickTime ? Object Virtual Reality to display the three-dimensional geometry offers asophisticated user experience and a convenient method for viewing virtual objects overthe web. With this work, I generate original High Dynamic Range images for thepurpose of image-based lighting and use the QuickTime ? Object Virtual Realityframework to creatively alter the paradigm of object VR for use in object lighting. Theresult is two scenarios: one that allows for the virtual manipulation of an object within alit scene, and another with the virtual manipulation of light around a static object. Futurework might include the animation of High Dynamic Range image-based lighting, withemphasis on such features as depth of field and glare generation.
