RGPV CS603(B) Computer Graphics & Visualization Unit 2 study material. Learn 2D transformations, translation, rotation, scaling, reflection, shearing, composite transformation, windowing, clipping, line clipping and polygon clipping.
Unit 2 explains how 2D objects are transformed and clipped in computer graphics. It covers the mathematical operations used to move, rotate, resize and display graphics objects inside a viewing window.
Understand translation, rotation, scaling, reflection and shearing of 2D objects.
Learn how multiple transformations are combined using matrix multiplication.
Study viewing transformation, line clipping and polygon clipping algorithms.
Complete syllabus-based topics of Computer Graphics & Visualization Unit 2.
Process of changing position, size or orientation of a 2D object in graphics.
Moving an object from one position to another by adding translation values to coordinates.
Turning an object about a fixed point by a specified angle.
Changing the size of an object by multiplying coordinates with scaling factors.
Producing mirror image of an object about x-axis, y-axis, origin or line y = x.
Distorting the shape of an object by shifting coordinates in x-direction or y-direction.
Combination of two or more transformations applied using matrix multiplication.
Selecting a rectangular area of world coordinates for display on the screen.
Removing parts of objects that lie outside the viewing window.
Mapping objects from world coordinate system to viewport coordinate system.
Algorithmic process of clipping lines against a rectangular clipping window.
Process of clipping polygon edges and vertices against clipping boundaries.
