等距视图
等距视图 一种三维物体的显示方法。绘制物体时每一边的长度都按绘图比例缩放，而物体上所有平行线在绘制时仍保持平行。例如，立方体的等距视图，其各面按对称关系绘制，各面的长宽保持同一比例关系，这不同于透视中，立方体中面的大小随距离增大而逐渐变小。比较 perspective view。【英】A display method for three-dimensional objects in which every edge has the correct length for the scale ofthe drawing and in which all parallel lines appear parallel. An isometric view of a cube, for example, shows thefaces in symmetrical relation to one another and the height and width of each face evenly proportioned; the facesdo not appear to taper with distance as they do when the cube is drawn in perspective.
