In this several transformations Translation, Rotation and Reflection took place. The line y = mx + b, can be achieved with a combination of translate-rotate-reflect transformation. Generally Reflection about any line in Computer Graphics is represented by any line, For easy understanding, we are providing detailed image analysis, which show both Horizontal and Vertical Reflections. When Image gets flipped up and down, the reflection is referred as Vertical Reflection. And here image gets reflected with respect to the Y-axis. When Image gets flipped across, then the Image reflection is known as Horizontal Reflection. Transformation in Computer Graphics Reflection is broadly classified in to Two Categories. As mentioned in the above X-axis, case the point gets reflected with respect to Y-axis and obviously point gets flipped. And similarly when the image gets reflected with respect to Y-axis is shown figure. But one must notice that, the image “Flips” 180 degrees and the values of Y of coordinate positions. Generally the image is original plane is represented with the points say 1,2,3, where as the reflected image is denoted with the same numbers with dashes say 1’,2’,3’ and likewise.Īs this image is reflecting with respect to the X-axis, the reflection transformation obviously keeps X-values same. So Image gets reflected with respect to any axis say X-axis or Y-axis. One must remember that, when the reflection axis is a line in the XY plane, say X-axis, the rotation path about this X-axis is in a plane which is perpendicular to the XY plane. So there we may choose axis of reflection in the XY plane. For that we need to rotate main object 180 Degrees about the reflection axis.įollowing figures are shown for better understanding of Computer Graphics Reflection.In the above figure, it shows the half of the above image is reflected with respected to the X-axis. Reflection is also a transformation in Computer Graphics.īasically the mirror image of any image for 2D reflection is generated with respect to the “Axis of Reflection”. The term’s meaning is available in the name itself “Reflection” that is a “Mirror Image” or “Duplicate Object” or “Replica” of an original object. In Computer Graphics subject, we need to study transformations such as Reflection and Shear. Computer Graphics Reflection Transformation is explained in detail.Computer Graphics is the Sub part of the Main Computer Science subject.Computer Graphics Reflection is used to reproduce the objects of Main images again which are shown on shiny surfaces or else using in mirrors.
