复杂场景的高保真绘制是计算机图形学的主要目标之一。不幸的是，高保真渲染是出了名的计算昂贵。在本文中，我们提出了一个框架，高保真渲染在合理的时间，通过我们的按需渲染系统。我们将两种主要的渲染加速方法结合在一起：选择性渲染和并行渲染。我们提出了一个选择性渲染系统，其中包括选择性指导。除此之外，选择性引导系统利用人类视觉系统中的限制来将渲染工作集中在图像中感知上最重要的特征上。并行渲染通过在多个计算节点之间分配工作负载来帮助进一步降低成本。我们提出了一个实现我们的框架作为照明模拟系统的辐射的扩展，增加了一个选择性的指导系统，可以利用视觉感知。此外，我们并行辐射和它的主要加速数据结构，辐射缓存，并使用选择性指导，以提高分布式工作负载的负载平衡。我们的研究结果表明，实施的有效性，从而潜在的渲染框架。
High-fidelity rendering of complex scenes is one of the primary goals of computer graphics. Unfortunately, high-fidelity rendering is notoriously computationally expensive. In this paper we present a framework for high-fidelity rendering in reasonable time through our Rendering on Demand system. We bring together two of the main acceleration methods for rendering: selective rendering and parallel rendering. We present a selective rendering system which incorporates selective guidance. Amongst other things, the selective guidance system takes advantage of limitations in the human visual system to concentrate rendering efforts on the most perceptually important features in an image. Parallel rendering helps reduce the costs further by distributing the workload amongst a number of computational nodes. We present an implementation of our framework as an extension of the lighting simulation system Radiance, adding a selective guidance system that can exploit visual perception. Furthermore, we parallelise Radiance and its primary acceleration data structure, the irradiance cache, and also use the selective guidance to improve load balancing of the distributed workload. Our results demonstrate the effectiveness of the implementation and thus the potential of the rendering framework.
