The dimensions of the view port are as follows: xvmin=0, yvmin=0, xvmax=5, yvmax=5. The dimensions of the rectangle are as follows: L(2, 2) and Top right(5, 5). Draw the final shape of the rectangle in the view port with proper coordinates. (4 minutes) Q 4 Define the terms clipping and Clipping window.

In-class Activity Design -2 Active Learning activity(ies) that you plan to do 1. The active learning strategy adopted is TPS(Think-Pair-Share) Explain the strategy by giving details of 1. What Teacher will do? The teacher shall pose two questions to the students and give them time to solve individually(for ~10 minutes) and ask them to form a pair and compare your answers with the other member of the pair after proper discussion(for ~7 minutes). After that the class has to share their view and answers with the rest of the pairs of the class(for ~5 minutes) 1. What Student will do? The students have been given ~10 minutes of time to solve the problems individually and then for the next ~7 minutes have to discuss with the other partner in the pair and then finally for the next ~5 minutes have to discuss with the rest of the class and provide justification for their answers. Justify why the above is an active learning strategy 1. Enter Justification Here Think –Pair –Share is an active learning strategy in which the students are provided with written documents and or a video about a particular topic before hand , so that the student applies his or her brain to understand the topic and then attempts some basic questions over such a topic and submits the out of class assignment and joins the in class activity on the scheduled day. The teacher asses the out of class assignment and comes to know about the problems faced by the students and discusses them before the in-class activity and then starts the in class activity by providing two questions to be solved individually first and then sharing with partners and then wit the rest of the class. This improves the overall learning of the student and develops an ability to self learn and then compare and share. In our case the students applied their brain and if minor mistakes were they were corrected at the pair end and finally during the share round , the confidence of the students got boosted up when the answers were compared.

In-class Activity Design -2 Peer Instruction Strategy – What Teacher Does Place this question to the students as in class activity. Q 1: Find the normalization transformation that maps a window whose lower left corner is at (1, 1) and upper right corner is at (3, 5) onto A view port that is the entire normalized device screen, and A viewport that has a lower left corner at (0, 0) and upper right corner (1/2, 1/2).

In-class Activity Design -2 Peer Instruction Strategy – What Teacher Does Place this question to the students as in class activity. Q 2: Find the complete viewing transformation that maps a window in the world coordinates with x extent 1 to 10 and y extent 1 to 10 onto a viewport with x extent ¼ to ¾ and y extent 0 to ½ in normalized device space, and then maps a workstation window with x extent ¼ to ½ and y extent ¼ to ½ in the normalized device space in to work station viewport with x extent 1 to 10 and y extent 1 to 10 on the physical display device.

In-class Activity Design -3 Peer Instruction Strategy – What Teacher Does Q 3) Let R be the rectangular window whose lower left hand corner is at L(-3, 1) and upper right hand corner is at R(2, 6). Find the region codes for the end points using Cohen Sutherland Line Clipping algorithm, also find the intersection points with the boundary of the window. Display your results with a final drawing of the clipped lines.
