  1. Introduction to Computer Graphics Compiled By : Mr.Faraz Khan

  2. Introduction : • What is Computer Graphics ? • Imaging = Representing 2D Images . • Modeling = Representing 3D Images . • Rendering = Constructing 2D Images from 3D Models. • Animation = Simulating changes over time.

  3. What is Computer Graphics? • Algorithms for Visual Simulations

  4. Main Themes • Imaging • Representing 2D images • Modeling • Representing 3D objects • Rendering • Constructing 2D images from 3D models • Animation • Simulating changes over time

  5. Imaging • WarpingWarping may be used for correcting image distortion as well as for creative purposes (e.g., morphing). The same techniques are equally applicable to video. • MetamorphosisImage metamorphosis, or image morphing, is a popular technique for creating a smooth transition between two images. • Non-Photorealistic RenderingIn computer graphics, photorealistic rendering attempts to make artificial images of simulated 3d environments that look "just like the real world." So non-photorealistic rendering (NPR) is any technique that produces images of simulated 3d world in a style other than realism.
