Detailed explanation-1: -When we want to place the object into a scene, we need to transform the object coordinates that we used to define the object into the world coordinate system that we are using for the scene. The transformation that we need is called a modeling transformation.
Detailed explanation-2: -The transformation matrix, between coordinate systems having differing orientations is called the rotation matrix. This transforms the components of any vector with respect to one coordinate frame to the components with respect to a second coordinate frame rotated with respect to the first frame.
Detailed explanation-3: -Transformation Rules on the Coordinate Plane The x and y values switch places. Rotation 180° about the origin: Each x and y value becomes opposite of what it was. Rotation 270° about the origin: Each x value becomes opposite of what it was. The x and y values switch places.
Detailed explanation-4: -Answer: b. Translation Explanation: Translation is an efficient transformation method in which an object may shift form one coordinate position to any other coordinate position in a three-dimensional plane.
