Description
Дл построени перспективного изображепи точки Л, линейку 3 подвод т к горизонтальной проекции этой точки AI. При этом линейка 4 определит перспективное изображение вертикального ребра с основанием в точке AI-линию - носитель точки А.To build a perspective image of a point L, a ruler 3 is brought to the horizontal projection of this point AI. In this case, line 4 will define a perspective image of a vertical edge with a base at the point AI-line - the carrier of point A.
Положение точки А определ етс на основе родства точек Лз и (при этом отрезок - высота точки А над предметной плоскостью). Дл этого к точке Лз подводитс линейка 3. При этом липейка 4 в пересечении с пр мой И определить точку напротив которой расположена искома точка А.The position of point A is determined on the basis of the relationship of the points Lz and (in this case, the segment is the height of point A above the subject plane). For this purpose, ruler 3 is brought to the point Lz. At that, line 4 at the intersection with the straight line And to determine the point opposite to which the desired point A. is located.
В процессе построени перспективных изображений других точек используетс тот же алгоритм.In the process of building perspective images of other points, the same algorithm is used.
Предусмотрено построение перспективы на наклонной плоскости и не с нулевым горизонтом (хот , эта задача встречаетс значительно реже, так как при построении перспектив высотных сооружений ростом человека можно принебречь). Дл таких точек (например, точка Ло) построение перспективного изображени выполн етс тем же алгоритмом.It is planned to build a perspective on an inclined plane and not with a zero horizon (although this task is much less common, since it is possible to neglect the construction of perspectives of high-rise structures with human height). For such points (for example, the Lo point), the construction of the perspective image is performed by the same algorithm.
Использование прибора дл проектноконструкторских работ обеспечивает ускорение процесса, выполнение графических операций и повышение точности построеНИИ .The use of the device for design work accelerates the process, performs graphic operations and improves the accuracy of construction.
