When working with mathematical simulations or engineering problems, it is not unusual to handle curves that contains thousands of points. Usually, displaying all the points is not useful, a number of them will be rendered on the same pixel since the screen precision is finite. Hence, you use a lot of resource for nothing!
This article presents a fast 2D-line approximation algorithm based on the Douglas-Peucker algorithm (see [1]), well-known in the cartography community. It computes a hull, scaled by a tolerance factor, around the curve by choosing a minimum of key points. This algorithm has several advantages:
這是一個基于Douglas-Peucker算法的二維估值算法。

This string-include defines all string functions as inline functions. Use gcc. It also assumes ds=es=data space, this should be normal. Most of the string-functions are rather heavily hand-optimized,
see especially strtok,strstr,str[c]spn. They should work, but are not
very easy to understand. Everything is done entirely within the register
set, making the functions fast and clean.
This book explains how to write, install, and debug device drivers for Windows 2000. It is intended to be a companion to the Microsoft DDK documentation and software.
Windows 2000 represents a major improvement to previous versions of Windows NT. Device drivers for Windows 2000 may be designed for the new Windows Driver Model (WDM) architecture. If so, the driver will be source compatible with Windows 98. This book covers the new WDM specification.
This book will also prove useful to those studying the internals of Windows 2000, particularly the I/O subsystem and related components.
Back in 2002, the 6502 disappeared out of all catalogues.
Wanted to know, if it s possible to build a binary compatible CPU with the things I had in the drawer:
74LS parts, 27C512 EPROMs and a fast static RAM from an old 80386 motherboard.
Now here the results.
Note, that the Bus timing is different from the 6502.
