While z-buffering allows the geometry to be unsorted, sorting polygons by increasing depth (thus using a reverse painter's algorithm ) allows each screen pixel to be rendered fewer times. 尽管深度缓冲可以处理未经排序的几何体,但是按照深度不断增加的方式(与画家算法 排序方式相反)对多边形进行排序,...
I'll end by discussing two rendering algorithms, the painter's algorithm and the Z- Buffer. QED An 8-bit z-buffer is almost never used since it has too little precision. WikiMatrix On recent PC graphics cards (1999–2005), z-buffer management uses a significant chunk of the available...
algorithm is also able to exploit temporal coherence. The method is well suited to models with high depth complexity, achieving orders of magnitude acceleration in some cases compared to ordi- nary Z-buffer scan conversion. CR Categories and Subject Descriptors: I.3.7 [Computer Graphics]: Three-...
Hierarchical Z-Buffer VisibilityNed Greene ∗ Michael Kass † Gavin Miller †AbstractAn ideal visibility algorithm should a) quickly reject most of thehidden geometry in a model and b) exploit the spatial and perhapstemporal coherence of the images being generated. Ray castingwith spatial ...
A buffer (also known as anti-aliased, area-averaged, accumulation buffer) is an extension to the Z buffer. A buffer algorithm was developed by Pixar. A buffer method could be used effectively for medium scale virtual memory computers. The same algorithm used by Z buffer is used with A buff...
This paper describes a new perspective on a fundamental algorithm of three-dimensional computer graphics, namely z-buffering. An implementation of the z-buffer method in a lazy functional language behaves in a manner quite different to its traditional imperative counterpart. The main result of this ...
"Of all image-space algorithms, the depth buffer algorithm is the simplest. For each pixel on the display screen, we keep a record of the depth of the object within the pixel that lies closest to the observer. In addition to the depth, we also record the intensity that should be display...
In this paper, we propose new algorithm for hidden surface removal method of computer generated holograms using Z-Buffer that is generally used in computer graphics. The result of optical experiments show that the method is applied to computer generated holograms....
