Abstract
We present an algorithm suitable for real-time, high quality rendering of complex objects. Objects are represented as a dense set of surface point samples which contain colour, depth and normal information. These point samples are obtained by sampling orthographic views on an equilateral triangle lattice. They are rendered directly and independently without any knowledge of surface topology. We introduce a novel solution to the problem of surface reconstruction using a hierarchy of Z-buffers to detect tears. Our algorithm is fast and requires only modest resources. 1 Introduction The research presented in this paper was motivated by a desire to render complex objects in real time without the use of expensive hardware. This ubiquitous goal has recently led to the use of images, rather than polygons, as primitives. Unlike traditional polygon systems in which rendering time is proportional to scene complexity, in image based systems rendering time is proportional to the number of pixels...
