چکیده

We are investigating methods to accelerate rendering of architectural walkthroughs. In this paper, we improve upon a cells and portals framework by using images to replace geometry visible through portals (doors and windows) in a three-dimensional model. We present several solutions: images texture-mapped onto the portal, 3D warping of single reference images, and 3D warping of layered depth images. We have achieved significant speedups and present the results of applying the techniques to large architectural models.

Accelerating Ray Tracing by Exploiting Frame-to-Frame Coherence

As 3d data sets become increasingly larger, and image sizes stay relatively constant, new rendering paradigms based upon images begin to offer significant advantages over traditional object based systems. Current image based systems, however, often assume a lack of the true 3d geometry, and so are limited to the views they can reproduce. We present an image space acceleration method for renderi...

Multiple strategy stochastic iteration for architectural walkthroughs

Architectural walkthroughs require fast global illumination algorithms and also accurate results from certain viewpoints. This paper introduces a global illumination method that combines several strategies to meet the contradicting criteria of architectural walkthroughs. The methods include parallel and perspective ray-bundle shooting and ray shooting. Each method is designed to randomly approx...

VEX-CMS: A Tool to Design Virtual Exhibitions and Walkthroughs That Integrates Automatic Camera Control Capabilities

This paper presents VEX-CMS, a tool to build 3D virtual museums and exhibitions, architectural walkthroughs and, more generally, applications where 3D and 2D content is presented to the user inside a 3D Virtual Environment. In this paper, we concentrate on the task of designing tours of the virtual environment to be followed by visitors, either through manual or automatic navigation, and show h...

Conservative Visibility Determination for Architectural Scenes

In this article I present a conservative visibility determination algorithm, particularly suited for interactive walkthroughs in architectural scenes. This algorithm is able to determine which parts of the scene are visible during an interactive real-time walkthrough. The algorithm consists of an off-line part, which preprocesses the scene, and an on-line part, which determines the potentially ...
