reflection and shearing in computer graphics program

Thus, New coordinates of corner C after shearing = (1, 3, 6).

Z new = Z old + Sh z x X old = 3 + 3 x 1 = 6.

Let the new coordinates of corner C after shearing = (X new, Y new, Z new). Thus, New coordinates of corner B after shearing = (1, 3, 5).

Z new = Z old + Sh z x X old = 2 + 3 x 1 = 5.

Y new = Y old + Sh y x X old = 1 + 2 x 1 = 3.

Let the new coordinates of corner B after shearing = (X new, Y new, Z new). Thus, New coordinates of corner A after shearing = (0, 0, 0).

Z new = Z old + Sh z x X old = 0 + 3 x 0 = 0.

Y new = Y old + Sh y x X old = 0 + 2 x 0 = 0.Let the new coordinates of corner A after shearing = (X new, Y new, Z new).Īpplying the shearing equations, we have. Shearing parameter towards Y direction (Sh z) = 3.Shearing parameter towards Y direction (Sh y) = 2.Shearing parameter towards X direction (Sh x) = 2.Apply shear parameter 2 on X axis, 2 on Y axis and 3 on Z axis and find out the new coordinates of the object. PRACTICE PROBLEMS BASED ON 3D SHEARING IN COMPUTER GRAPHICS. Shearing in Z axis is achieved by using the following shearing equations. Shearing in Y axis is achieved by using the following shearing equations. In Matrix form, the above shearing equations may be represented as. Shearing in X axis is achieved by using the following shearing equations. New coordinates of the object O after shearing = (X new, Y new, Z new).Shearing parameter towards Z direction = Sh z.Shearing parameter towards Y direction = Sh y.

Shearing parameter towards X direction = Sh x.Initial coordinates of the object O = (X old, Y old, Z old).So, there are three versions of shearing-Ĭonsider a point object O has to be sheared in a 3D plane. In a three dimensional plane, the object size can be changed along X direction, Y direction as well as Z direction. In this article, we will discuss about 3D Shearing in Computer Graphics.ģD Shearing is an ideal technique to change the shape of an existing object in a three dimensional plane. In computer graphics, various transformation techniques are. 3D Transformations take place in a three dimensional plane.Transformation is a process of modifying and re-positioning the existing graphics.
