想问一下三维是什么?
三维指的是:
三维是指在平面二维系中又加入了一个方向向量构成的空间系。三维既是坐标轴的三个轴,即x轴、y轴、z轴,其中x表示左右空间,y表示前后空间。
z表示上下空间(不可用平面直角坐标系去理解空间方向)。在实际应用方面,一般把用X轴形容左右运动,而Z轴用来形容上下运动,Y轴用来形容前后运动,这样就形成了人的视觉立体感。
三维的绘制:
在工程设计和绘图过程中,三维图形应用越来越广泛。AutoCAD可以利用3种方式来创建三维图形,即线架模型方式、曲面模型方式和实体模型方式。线架模型方式为一种轮廓模型,它由三维的直线和曲线组成,没有面和体的特征。
表面模型用面描述三维对象,它不仅定义了三维对象的边界,而且还定义了表面即具有面的特征。实体模型不仅具有线和面的特征,而且还具有体的特征,各实体对象间可以进行各种布尔运算操作,从而创建复杂的三维实体图形。
iqooz5游戏空间怎么开?
游戏空间的开启 *** :

四维空间
一楼已经解释,我想说的,不知你是否赞同。我们不管空间的维度是怎么形成的,我们先看看空间维度对空间本身的影响,总结规律,做出高维度空间的推论,首先,零维是点,一维是线,二维是面,三维是体,而三维以及三维以上的空间,我们都可以将它认识成体,在庞大的三维空间内,作为一个人,是非常渺小的,我们眼前的事物也是微乎其微的,所以我们所能看到的,所能接触到的,在三维空间内可看做是一个点,而在庞大四维空间内,我们,以及我们能看到的能接触到的,依旧可以看做是一个点,那么就算空间由三维变成四维,做为空间内的一个点来说,其实没有变化,所以在四维空间内,我们并不会感受到空间的变化,如果在一个远离地球的地方看地球,才会发现地球原来发生了很大的变化。那么四维空间与三维空间有什么不同?不同之处就是生物,我们生活在一个三维基本维度是x.y.z的空间,如果空间基本维度变成x.y.z.a,那么我们这个空间至少会和一个空间合并,被合并的空间本身就是x.y.z.a,也就是说,我们可以看到本身就活在四维的生物,我们也有可能和其他三个空间合并,分别是x.y.a/x.z.a/y.z.a。因为这三个空间也有变成x.y.z.a这样四维空间的可能。
