B-Spline Surface Implementation with OpenGL
In this implementation, instead of using any B-Spline built-in functions of OpenGL, I made my own functions calculate points on surface base on given knots and control points. OK, let’s start! Basic Information First of all, I want to specify some notations in this implementation. Here are two core expression…

Slove the problem that can’t accesses sina.com.cn in some regions
Recently I met some problems that can’t accesse Chin site sina.com.cn and weibo.com in Korea. Ping sina.com.cn, reassault is that Sina.com.cn has been pointing to 127.0.0.1. This ip is local address, maybe have been maliciously tampered. The soulution is very simple, use the serve of Opendns. Open “Settings” – “network connections” to find…
