查询词典 polygons

Then I will extrude the polygons and align them how I think is right.

然后我会挤出多边形，并调整他们如何，我认为是正确的。

Secondly, some foundational arithmetic such as the division of concave polygon, the polygons boolean operation, the transform from circle to polygon, the pick-up of model top surface were designed particularly based on OpenGL.

然后，基于图形库OpenGL完成了包括凹多边形的分割、多边形的布尔运算、圆的多边形转化、模型上表面获取等基础算法；并针对已建模工艺设计了相应的仿真算法。

First the math theory of machining simulation is studied, and the set structure of NC machining simulation system whose components, including time, input, output and so on, are defined. Hereby we set up the hierarchy structure, the logical structure, the static model and the dynamic model of simulation system. The construction method of sweep entity of cutter and rotation parts is researched, and their differential geometry invariants are calculated. NC code is unscrambled, and the recursion division arithmetic of time segment is put forward, which is the driven data of the movement or rotation parts. The CLDATA should be interference-free. To examine if there is interference between cutter flank and the work piece, an arithmetic that discussed the existence of intersecting curve between them is put forward. To examine if there is interference between two turrets, an arithmetic that discussed the existence of intersection set between two polygons is put forward.

首先研究加工过程仿真的数学基础，然后定义数控加工仿真系统的集合结构及时间集、输入集、输出集等概念，建立加工仿真的层次结构和逻辑结构，阐述双刀车削仿真系统的静态模型和动态模型建立方法，分析刀具扫描体和旋转部件扫描体的建立方法及其微分几何性质；研究NC代码解读技术和双刀加工时间段递归子分划技术，为驱动各仿真单元作数据准备；通过讨论后刀面和工件表面交线的存在性判断刀具后刀面与工件间是否干涉，通过求多边形的交集判断刀架与刀架是否干涉。

Just as with ordinary polygons, these will be formed from lines but with angles of 45 or 90 degrees between them.

正如普通多边形，它们由线条构成，但线之间的角度为45或90度。

The creation of a buffer zone is not in itself an analysis , but the new polygons that are created can be used in analysis.

一个建立的环域是不对自已进行分析的，但是新的多边形被建立后是可以被用来分析的。

The polygons in the centre (that should still be un-bevelled) where given a texture called WindowGlass, and the bevelled polygons were given a texture called WindowFrame.

在中心（多边形，应该仍然是联合国斜面）在给定名为WindowGlass纹理和多边形的斜面给予所谓WindowFrame纹理。

The reason you want to do this is so that you can avoid obvious lumpiness, misshaped details, pinching, etc. When it came to Paragalis I went from the base mesh "body only" which was 2064 polygons to the third subdivision level, which was 33,024 polygons.

你之所以要这么做是为了让你能避免明显凹凸不平，有些变形的细节，捏等，当我来到Paragalis从基地网&的机构只有&这是2064多边形细分到第三级，这是去33024多边形。

A testing triangulation experiment for a polygon with 100 inside islets was done with this algorithm, and the result showed that this algorithm is efficient and robust for triangulating complex polygons with large numbers of inside islets. This algorithm has been successfully applied to the three- dimensional ore-body modeling and visualization system, in which it is used to triangulate the sectional polygons with inside islets, e.g., the inside stones or holes in ore-body, and its high efficiency has been proved.

实验表明，该算法在含有大量岛屿的带岛屿多边形三角剖分中具有很高的时间效率和很强的鲁棒性，并成功将其应用到基于剖面的三维矿体建模与可视化系统中，解决了含有夹石或孔洞的矿体剖面多边形三角剖分问题，具有一定的实际应用价值。

The elements are also used to get the section polygons of such composite surfaces as the whole aircraft at a given body station, then a section area is approximated with the sum of trapezoidal areas between such sides of polygons that are not covered by any other component and a reference axis.

离散出的面元还被用于求取全机这样的组合曲面在某一站位处的横剖面多边形，而横截面积则用累积多边形不被其他任意部件遮挡的各边与参考轴间的梯形面积予以近似。

For example, a cube is made up of six quadrilaterals where each vertex is shared by three polygons, but a different normal should be used for each of the three instances of each vertex, but a sphere is made up of many polygons where all vertices have common normals.

例如，一个立方体是由六个四边形组成，而每一个顶点被三个多边形共用，但是每一个顶点的三个实例应该使用不同的法向量，而由许多多边形组成的球，其所有顶点就有同样的法向量。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
