This proposal introduces an innovative modeling and rendering primitive, called the O-buffer, for sample-based graphics, such as images, volumes, and points. The two-dimensional or three-dimensional O-buffer is in essence a conventional image or a volume, respectively, except that samples are not restricted to a regular grid. A sample position in the O-buffer is recorded as an offset to the nearest grid point of a regular base grid (hence the name O-buffer). The offset is typically quantized for compact representation and efficient rendering. This project investigates and develops representations, algorithms, applications, and a software system for O-buffers. The intellectual merits of the O-buffer are that it is more precise than a conventional image or volume, provides a more compact representation relative to a finer grid, accelerates rendering and supports low-bandwidth communications, improves image quality, is a flexible representation (e.g., non-regular, non-uniform, multi-resolution), and is a unified framework that can represent, render, and mix unstructured primitives. O-buffers can be harnessed in numerous applications, such as improving simulation systems, scientific visualization, Internet graphics, design and manufacturing, and health care, as well as enhancing and upgrading many other computer systems that use sampled-based data, such as images.

该提议引入了一种创新的建模和渲染原语，称为O-buffer，用于基于样本的图形，如图像、体积和点。二维或三维o型缓冲本质上分别是传统的图像或体积，只是样本不受规则网格的限制。o缓冲区中的样本位置被记录为距离规则基网格最近的网格点的偏移量（因此称为o缓冲区）。为了紧凑的表示和高效的呈现，偏移量通常被量化。该项目研究并开发了o缓冲区的表示、算法、应用程序和软件系统。O-buffer的智力优点是，它比传统的图像或体积更精确，相对于更精细的网格提供更紧凑的表示，加速渲染并支持低带宽通信，提高图像质量，是一种灵活的表示（例如，非规则、非均匀、多分辨率），并且是一个可以表示、呈现和混合非结构化基元的统一框架。o缓冲可以在许多应用程序中使用，例如改进仿真系统、科学可视化、Internet图形、设计和制造以及医疗保健，以及增强和升级使用基于采样的数据（例如图像）的许多其他计算机系统。
