Translation Translation can be thought of as moving something. h> #include<conio. Texture T=(s, t): In computer graphics, we often wrap a 2D image to an object to make it seen realistic. Most common geometric transformations that keep the origin fixed are linear, including rotation, scaling, shearing, reflection, and orthogonal projection; if an affine transformation is not a pure translation it keeps some point fixed, and that point can be chosen as origin to make the transformation linear. Such view is called perspective view. nowww. . More about that later. A transformation is any operation on a point in space (x, y) The convention is that the direction of the rotation is CCW if ø is a positive angle and CW if the ø is a negative angle. "Rotation transforms are used everywhere in computer graphics from rotating pictures in editing software, to providing an arbitrary view of a 3D virtual environment. . Shear along x axis (What is the matrix for y axis shear?)There are several transformations that are used in computer graphics, but the most common ones are translation (moving the object), rotation (spinning it) and scaling (changing its size). The matrix for rotating a point about an origin in a 2D plane is defined as: Thus the rotation of a 2D vector in a plane is done as follows: For example: To rotate a vector 90 degrees counterclock-wise is done as follows: A rotation transform, for our purposes here, rotates each point about the origin, (0,0). » Next Page - Computer Graphics Questions & Answers – 2D Rotation « Computer Graphics Questions & Answers – Area Sampling.
