The scene has light grey colored chair having RGB components (0.5,0.7,0.8). He has used four light sources. In terms of RGB the intensities of light sources are l1(0.4,0.7,0), l2(0.2,0.1,0.5), l3(-0.5,-0.6,0.5) and l4(-0.1,-0.2,0 ) ; Light source 3 and light source 4 are dark lights having negative colors. a) What will be the final light intensity? (5 marks) b) Calculate the overall color contribution of light in relation to the object surface? (5 marks) c) What color component(s) will remain absent from the scene? (3 marks) d) Which color the object will look like in presence of the light sources? (2 marks) Hint: (You may check final color intensities given in color.pdf file) Question No 2: Marks=05 Fiber Optics are widely used as optic cables to transmit light signals over long distances with minimal loss of data. It works on the principle of total internal reflection. [image: u58vYFM.png] In order to simulate the fiber optic in computer graphics, calculate the critical angle where the inner core of fiber has index of refraction 1.5 while the cladding has index of 1.3.

Total Marks 5 Starting Date Thursday, August 01, 2019 Closing Date Friday, August 02, 2019 Status Open Question Title GDB-CS602 Question Description Graded Discussion Board Anti-aliasing is a technique that eliminates the staircase effect (visual defect) on the edges of objects in images at lower resolution. At moderate resolution, aliasing becomes negligible and can be ignored but the drawback becomes bold when the picture is moving. FXAA (Fast Approximate Anti-Aliasing) and SSAA (Super Sampling Anti-Aliasing) are two famous anti-aliasing algorithms suitable for games. Discuss which algorithm will be best suitable for the new release of PC video game by ABC software house. Consider more users will generate more revenue and every user has not powerful system. Read the following instructions carefully before sending your comments: Your discussion must be based on logical facts and in depth knowledge of topic is must for that. Your comments should be relevant to the topic i.e. clear and concise. (Maximum 4-5 lines answer). You should post your comments on Graded Discussion Board & not on the Regular MDB. Both will run parallel to each other during the time specified above. Books, websites and other reading material may be consulted before posting your comments. GDB will have weight-age of 5% of your total subject marks. No extra time will be given for discussion. You cannot participate in the discussion after the due date or through e-mail.
