查询词典 hyperboloids

Such gears are called hypoid gears because their pitch surfaces are hyperboloids of revolution.

这种齿轮是所谓的准双曲面齿轮，因为他们的沥青表面hyperboloids的革命。

Using two hyperbolas the system can obtain 2D target position, while using at minimum three hyperboloids the system can achieve full 3D target locating.

使用二个双曲线系统能获得2D目标位置，当使用最少三个双曲面系统能达成完整的3D立体目标定位。

Using two hyperbolas the system can obtain 2D target position, while using at minimum three hyperboloids the system can achieve full 3D target locating.

使用二个双曲线系统能获得2D目标位置，当使用最少三个双曲面系统能实现完整的3D立体目标定位。

More often, we need to design subdivision schemes for certain known surfaces. Unfortunately subdivision scheme can do little for this, even for some simple but of basic importance curves and surfaces (such as ellipsoids and hyperboloids).

仅仅修改交点处的拓扑结构不能确保每条折痕整体的C〓连续性，所以我们在修改交点处拓扑结构的同时，还修改了交点附近的细分格式，从而确保了每条折痕整体的C〓连续性。

Such gears are called hypoid gears because their pitch surfaces are hyperboloids of revolution.

因为他们的沥青表面是革命， hyperboloids这样齿轮称准双曲面齿轮的齿轮。

It uses the card to fill the Grimm type reflecting system, is composed by two hyperboloids reflectors, is the caliber 2.4 meters main mirrors, another is installs in front of the host mirror approximately 4.5 meters place vice- mirrors, the caliber 0.3 meter.

它采用卡塞格林式反射系统，由两个双曲面反射镜组成，一个是口径2.4米的主镜、另一个是装在主镜前约4.5米处的副镜，口径0.3米。

Traditionally ellipsoids and hyperboloids are modeled as implicit surfaces or through the use of rational surface schemes. The existing methods for generating spheres or quadrics have shortcoming such as the rational parameterizations for these surfaces are non-uniform, the resulting scheme cannot represent these surfaces in their natural acr-length parameterization and the implementation of the scheme is complex.

长久以来，Subdivision方法对一些看似简单却又在计算机图形学中有着重要作用的曲线曲面的造型非常困难，即使是对简单的圆和球的生成也很困难，已有的一些生成球或二次曲面的Subdivision方法一般都有太复杂、不能自然弧长参数化或者计算量太大等缺点。
