Notes for Projection of Points and Lines

The paper contains the classification of singularities for plane projections of smooth surfaces by means of a pencil of straight lines originating from a point 14 normal forms. The points of a surface in general position are divided into classes which define the projection type along an arbitrary direction with almost every point of the tangent to that direction as the projection center. Only isolated points on isolated asymptotic straight lines turn out to be exceptional. Such points are called focal. Singularities of the set of focal points are studied in the paper.


In mathematics , a plane is a flat, two- dimensional surface that extends infinitely far. A plane is the two-dimensional analogue of a point zero dimensions , a line one dimension and three-dimensional space. Planes can arise as subspaces of some higher-dimensional space, as with one of a room's walls, infinitely extended, or they may enjoy an independent existence in their own right, as in the setting of Euclidean geometry. When working exclusively in two-dimensional Euclidean space , the definite article is used, so the plane refers to the whole space. Many fundamental tasks in mathematics, geometry , trigonometry , graph theory , and graphing are performed in a two-dimensional space, or, in other words, in the plane.

Symbiosis Institute of Technology, Pune. An object is represented by boundaries of all surfaces of the object. The boundary of surface may be made up of straight lines or curves or both. As such lines and curves made up of number of points, is logically started with projection of points. Figure 1 Plane of projectionProjection of points Figure 2 Quadrant System Based on the quadrant system shown in figure 2,the space is divided in to four parts. The point in the different quadrants are defined as, Symbiosis Institute of Technology, Pune. From given data identify the quadrant2.

Oblique Surfaces 8. Includes a large number of dimensioned illustrations, worked-out examples, and Polytechnic questions and answers to explain the geometrical drawing process. If you were given the responsibility of going to a store and purchasing a throw rug that had to fit within a room in your home, how would you communicate the shape and size of the room to the salesperson?.

Его сверхкритическую массу. - М-м… сто десять фунтов, - сказала Соши. - Сто десять? - оживился Джабба.  - Сколько будет сто десять минус тридцать пять и две десятых. - Семьдесят четыре и восемь десятых, - сказала Сьюзан.  - Но я не думаю… - С дороги! - закричал Джабба, рванувшись к клавиатуре монитора.  - Это и есть ключ к шифру-убийце.

 - Уран и плутоний. Давай. Все ждали, когда Соши откроет нужный раздел. - Вот, - сказала.  - Стоп.

Куда она могла уйти. Неужели уехала без меня в Стоун-Мэнор. - Эй! - услышал он за спиной сердитый женский голос и чуть не подпрыгнул от неожиданности. - Я… я… прошу прощения, - заикаясь, сказал Беккер и застегнул молнию на брюках. Повернувшись, он увидел вошедшую в туалет девушку. Молоденькая, изысканной внешности, ну прямо сошла со страниц журнала Севентин.

 Слишком поздно, - сказал Стратмор. Он глубоко вздохнул.  - Сегодня утром Энсея Танкадо нашли мертвым в городе Севилья, в Испании.

 Как он выглядит - на фото. Быть может, я смогу его узнать. - Ну… - произнес голос.  - Он очень, очень полный. Ролдан сразу понял.

 Ш-ш-ш, - утешал он .
