Initial Point − For a vector AB, A is referred as an initial point. Certain terminologies are equally important for a vector which are mentioned below − It includes length in magnitude and with an arrow indicating the direction. The schematic representation of a vector can be considered as a directed line segment. Definition of VectorĪ vector can be defined as an object which includes both magnitude and direction. Now let us focus on various terminologies of a vector. The snapshot shows the representation of one vector four times, once for each point of the face. The "same distance and direction" is a vector, shown in the figure above as a line with an arrow head. If a user tries to move the same distance and direction from each of these points for a specified cube, it is observed that you reach the four vertices of the back face.
The front face includes four vertices which can be referred as four points. The best illustration for this is a cube. Most often the same displacement is applied to each of several points in 3D view. This combination of "distance and direction" for a vector is referred as a displacement. This property makes 3D computer graphics easy to understand and interpret. If this happens, then it is considered as a line segment. The vector will never include a fixed location in space. Direction includes the path where a vector defines its initial and end point. Length defines the distance between start and end point. A geometrical vector includes two major properties which are mentioned below − The following figure refers to the schematic representation of vector −Ī point indirectly defines a vector. With respect to computer graphics, a point is usually considered as a vertex of 3D figure. A point does not have any predefined size, the only unique property it includes is location. In geometry and 3D mathematical model, a point is a location in space. The 3D mathematical model always refers to vectors as their basic points.
