<p><span style="color:hsl(0,0%,0%);">In this video, we will be studying in depth about the 3D Rotation which is one of the 3D transformation method. Transformation is a way of modifying and changing the position of an existing object in computer graphics. 3D transformation manipulates the view of 3D object based on its original position by simply modifying the physical attributes of that object by using various methods of transformation like translation, rotation, scaling, shear, etc. </span><br><br><span style="color:hsl(0,0%,0%);">3D transformations can be drawn on a 3D plane. 3D transformations are more complex than 2D transformations and are very important and helpful in changing the shape of an object, the size of an object, the position of an object, etc.</span><br><br><span style="color:hsl(0,0%,0%);">The different types of transformations that are used in computer graphics are:</span><br><span style="color:hsl(0,0%,0%);">- Translation</span><br><span style="color:hsl(0,0%,0%);">- Scaling</span><br><span style="color:hsl(0,0%,0%);">- Rotation</span><br><span style="color:hsl(0,0%,0%);">- Shearing</span><br><span style="color:hsl(0,0%,0%);">- Reflection</span><br><br><span style="color:hsl(0,0%,0%);"><strong>Rotation:</strong> 3D rotation rotates the object based on an angle in three dimensional environment. 3D rotation deals with 3axis X,Y, and Z axis. It is not smae as the 2D rotation. Here object can rotate an object parallel to a specific axis so that the coordinate where the object rotates, remains unchanged and the remaining two get changes. </span><br><br><span style="color:hsl(0,0%,0%);"><strong>Three kinds of such rotations are possible:</strong></span><br><br><span style="color:hsl(0,0%,0%);"><strong>1) Rotation about the X-axis: </strong>Here the x coordinate remains unchanged and the rest two coordinates y and z change , It rotates parallel to the x-axis .</span><br><span style="color:hsl(0,0%,0%);"><strong>2) Rotation about the Y-axis:</strong> Here the y coordinate remains unchanged and the rest two coordinates x and z change, it rotates parallel to the y-axis .</span><br><span style="color:hsl(0,0%,0%);"><strong>3) Rotation about the Z-axis:</strong> Here the z coordinate remains unchanged and the rest two coordinates x and y change, it rotates parallel to the z-axis</span><br><br><span style="color:hsl(0,0%,0%);">Note: Rotation angle in the Anti-clockwise direction is considered as +ve, whereas in the clockwise direction rotation angle is considered -ve.</span><br><br><a href="https://www.geeksforgeeks.org/computer-graphics-3d-rotation-transformations/"><span style="color:hsl(0,0%,0%);">3D Rotation Tranformation Technique in Computer Graphics: https://www.geeksforgeeks.org/computer-graphics-3d-rotation-transformations/</span></a></p>
