exam.1 Si23_03 SI23 Introduction to Computer Graphics Revision Lecture

exam.2 Si23_03 Format of Exam n Length: 1 hour 15 minutes n Closed Book n Rubric: answer 2 questions out of 3

exam.3 Si23_03 Typical Question n First part (10 marks): – A question (maybe several parts) addressing a particular area of the module – eg line drawing algorithms n Second part (10 marks): – 6 statements which are either true or false – Say whether true or false – If false, replace with corrected statement

exam.4 Si23_03 Coverage n Over the three questions I am aiming to cover the whole of the material from the lecture part of the module – Images – Colour – 2D vector graphics – including graphics algorithms – 3D graphics – including modelling, viewing, projection and rendering – SVG, OpenGL, VRML n Be prepared to think!

exam.5 Si23_03 Example of True and False n Q: SVG stands for Simple Vector Graphics n A: SVG stands for Scalable Vector Graphics n A: SVG stands for Scalable Vector Graphics (the scalability allowing the graphics to be displayed at different resolutions) n A: SVG stands for Scaled Vector Graphics n A: SVG stands for Scaled Vector Graphics (the scaled notion indicating the graphics can be displayed at different resolutions)

exam.6 Si23_03 Another Example n Q: Gouraud shading achieves a smooth rendering appearance because it uses interpolated normals at each point in polygon n A: Phong shading uses interpolated normals; Gouraud calculates reflected colour at vertices and then interpolates these colours within polygon.

exam.7 Si23_03 Questions?
