![]() Following figure show right-hand orientation of the cube. In the right -handed system thumb of right- hand points to positive z-direction and left- hand system thumb point to negative two directions. Right-handed system and left-handed system. The orientation of a 3D coordinate system is of two types. Three dimension system has three axis x, y, z. In the production of a realistic 3D scene from 2D is tough. It also provides automobile bodies, aircraft parts study. CAD allows manipulation of machine components which are 3 Dimensional. In 3D also we can represent a sequence of transformations as a single matrix.Ĭomputer Graphics uses CAD. Each can be performed along any three Cartesian axis. In 3D when a translation is done we need three factors for rotation also, it is a component of three rotations. Using 3D, we can see different shapes of the object in different sections. But some more natural objects can be represented using 3D. More complex transformations are handled using matrix in 3D. These are also called as basic transformations are represented using matrix. These are translations, scaling, and rotation. In 2D two coordinates are used, i.e., x and y whereas in 3D three co-ordinates x, y, and z are used.įor three dimensional images and objects, three-dimensional transformations are needed. The three-dimensional transformations are extensions of two-dimensional transformation.
