An improved fast shadowing technique fit for the calculation of electromagnetic field is proposed in this paper based on the shadowing technique of z-buffer in computer graphics. The traditional shadowing algor
The Z buffer is a two-dimensional array (X and Y) that stores the Z-value of each screen pixel. If another object must be rendered at the same pixel location, the algorithm overrides the previous value if the new pixel is closer to the camera. This algorithm increases rendering speed ...
3.1 Painter’s Algorithm画家算法 先光栅化远处,再一步步处理近处 有一定的适用性 但是如果遇到这种相互遮挡的情况就不适用了 3.2 Z-Buffer 对于像素进行深度排序,同时生成两张图:Frame Buffer储存color value 和 Depth Buffer储存depth 伪代码 Frame Buffer 和 Depth Buffer 深度处理 Z-Buffer:并不是在做排序,而是...

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...
Z-buffer data In computer graphics , z-buffering , also known as depth buffering , is the management of image depth coordinates in 3D graphics , usually done in hardware, sometimes in software . 在计算机图形学 中,深度缓冲 是在三维图形中处理图像深度坐标的过程,这个过程通常在硬件 中完成,它也...
3Approach Notification Algorithm Our simulator has been required to have a function of alert notification. It is that the system has some notification event, when a virtual scalpel model is come closed to blood vessels. In order to realize this function, it is using the Z-buffer to measure ...
The depth value is also known as Z-buffer value. LASER-wikipedia2 Some information may be shared between the sub-pixels (such as the Z-buffer.) WikiMatrix I'll end by discussing two rendering algorithms, the painter's algorithm and the Z- Buffer. QED An 8-bit z-buffer is almost...
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-...
