Abstract:This paper proposes an acceleration method for direct volume rendering (DVR). Our approach works like a wrapper or braces surrounding raycasting implementations and requires very few changes to the existing code. Visualization systems can significantly improve their rendering performance in virtual reality setups and make DVR feasible in these environments. The first step—the opening brace—modifies the initial ray construction by adaptively reducing the ray density, hence feeding fewer rays to the raycaster. T… Show more
