查询词典 Point Four

The accelerated algorithm of volume rendering based on textures mapping and the wavelet-based multiresolution volume rendering in network are performed by using OpenGL 3D visualization technique. From the point of view of computer graphics, 3D visualization mechanism of volume rendering based on OpenGL textures mapping is studied, including modelview transformation, projection transformation, perspective division, viewport transformation and the ways to embed textures mapping and blending in above four transformations.

利用OpenGL三维可视化技术实现了本文所提出的基于纹理映射的体绘制加速算法和网络环境下基于小波的体数据的多分辨率体绘制，并从计算机图形学的角度，研究了基于OpenGL纹理映射技术的体绘制的三维可视化流程，包括OpenGL的模视变换、投影变换、透视除法、视区变换，以及纹理的定义、映射与融合等步骤在上述四个变换中的嵌入方法。

Each cell was mapped by the center point on the cell of transverse section with extended up and down for four pixel(nine-pixel lengths in total) and two pixels in width,and thereafter line convoluted dot map was obtained.

把每个纤维细胞都用其中心的一个长9个像素点、宽2个像素点的线段点图表示，进行傅立叶变换，其能量光谱图在水平和垂直方向上的频率分布，除零值以外的最大值，即为细胞径向、弦向直径。

Each cell was mapped by the center point on the cell of transverse section with extended up and down for four pixel (nine-pixel lengths in total) and two pixels in width, and thereafter line convoluted dot map was obtained. Through Fourier transformation, the frequency distribution of power spectrum pattern from both horizontal and vertical direction was obtained, and the cell diameter in radius and tangential direction was known from the maximum value except 0 in the distribution.

把每个纤维细胞都用其中心的一个长9个像素点、宽2个像素点的线段点图表示，进行傅立叶变换，其能量光谱图在水平和垂直方向上的频率分布，除零值以外的最大值，即为细胞径向、弦向直径。

In the double challenge only one point for us and four for them is not right in my opinion.

The four basic types of data recognized by C are integer, floating point, double precision, and character.

C 能识别的四种基本的数据类型是：整型、浮点型、双精度型和字符型。

With every new guideline and selling point, each diet acknowledges that there are really four basic rules to healthy eating drumroll, please

随着每一个新的指导方针和卖点的出现，每个饮食习惯都得承认，对于健康的饮食确实有4个基本规则

Since these merits, Dyn's four-point scheme is one of the classical subdivision schemes in CAGD.

本文讨论的是前者。1987年，Dyn提出了四点细分算法，它形式简单，最高具有四次收敛阶，并可以生成一阶连续的极限曲线，由于这些明显的优点，四点法成为CAGD中经典的细分算法。

Firstly, we give the geometric interpretation of the scheme.Secondly, we use the method developed in Dyn's original four-point paper to discuss the sufficient conditions for the limit curve to be C0,C1,C2 respectively.

首先给出了算法的几何意义，然后我们用Dyn在1987年发表的四点法中使用的办法，详细讨论了极限曲线连续，一阶连续，二阶连续的充分条件。

We analyses four main models of anti-monopoly authority institution, and point that efficient power is very important to anti-monopoly authority.

本文首先对各国反垄断执法机构组织体制的四种典型模式进行比较分析，并认为拥有充分的执法权力是反垄断有效执法的关键。
