Data Acquisition and 3D Modelling - Essay ExampleThe triangulation method is workoutd to infer the break through and their 3D nature in this method. It is known as stereoscopy because it uses two cameras. This is a computationally complex task but now a years it is carried out very successfully with the most modern and sophisticated equipments. This proficiency is good for apparent physical object reconstruction.The active form of stereoscopic methods use strong source of light to acquire 3D data of a physical object. Laser light source are used typically. It can totally be employed for industrial usage with a provision of controlled environment.3D or three dimensional modeling refers to the making of a real dry land object by making use of the actual geographical coordinates of the model. 3D modeling usually refers to the execution of 3D computer graphics by use 3D software. This specialized software functions by creating a set of points in 3Dimensional space. These points are connected together by various geometric shapes. These shapes may provided be a line, a dot, a triangle or a curved surface. There are four important methods upon which 3Dimensional models are created.Polygonal modeling. three Dimensional models are often created as polygonal models that are textured. In Polygonal Modeling a 3D model is created by connected the points in a 3D space with a line segment. These dots or points are generally referred to as vertices when talked about with reference to space. An avid benefit of this modeling technique is that it can be structured and adapted very conveniently by a computer system. This is owing to the fact that Polygonal models are very flexible. A slight disadvantage that is associated with Polygonal modeling is that it cannot be sued to perfectly structure curves.Primitive modeling. By far, the simplest method of modeling a 3D object is 3D Modeling. This method makes use of pre-defined mathematical/geometric shapes such as cylinder, sp here, cube, cone etc. Using these basic geometrical
