Furthermore,we present the method for designing quadratic Bezier developable surface:give four corner points of developable surface and two free designing parameters,the other two control vertexes are on the line connecting the linear interpolation point between the first two control vertexes and the linear interpolation point between the last two control vertexes,and they are the linear interpolation points between these two linear interpolation points respectively,namely,these four linear interpolation points are colinear.

提出了二次Bézier可展曲面的设计方法：给定可展曲面的4个角点a0、b0、a2、b2和两个自由设计参数？姿、？滋，则待求的2个控制顶点a1、b1是在前2个控制顶点a0、b0的线性插值点a*与后2个控制顶点a2、b2的线性插值点b*的连线上，并且也是a*、b*这2个线性插值点的线性插值，即这4点a*、a1、b1、b*共线。

The algorithm is concerned with selection of color spaces and analysis from point to plane and back from plane to point.

它涉及到对颜色空间的选取，以及由点到面再回到点的分析方法。

Each projected point is painted in color of the point nearest to the axis OX.

每个投影点涂上离OX轴最近的线段上的点的颜色。

This procedure can help you obtain the color designated point and click a picture, it can show that the color of the point!

这个程序可以帮助大家获得指定点的颜色，只要点击图片，便可以显示该点的颜色！

Once the intersection point is found, all that is left is to determine the color and normal at the point of intersection.

一旦找到了交点，接下来就需要确定交点的法向和颜色。

Heidegger's acerbic descriptions of "idle talk" or Gerede is a well known point in case: Idle talk and pointless chatter are from the philosopher's point of view a kind of degeneration of real or authentic communication; instead of a common exploration of the truth, we engage in a repetitive exchange of commonsensical trivialities.

海德格尔对"闲谈"的尖刻描述可以作为一个很好的例子：从哲学家的观点来看，闲聊和无关紧要的闲谈是一种真实的或本真的交流的退化，其中，我们不是在从事对真理的共同探究，而是在重复性地交流一些常识性的鸡毛蒜皮的东西。

From the point of view of the need, fulfilling environmental responsibility is an inevitable requirement of the Sustainable Development Concept and the Scientific Development Concept. From the point of view of the possibility, the rise of Communitarianism will play a catalytic role on the implementation of environmental responsibility.

如果从宏观层面进行理论划分的话，环境责任观念是责任伦理的组成部分；从必要性的角度看，履行环境责任是可持续发展观与科学发展观的必然要求；从可能性的角度讲，共同体主义的兴起将对环境责任的落实将起到促进作用。

"Second Life is remarkably easy to work with, and is very popular,"
