The distance between blocks is 210 meters.Each block has its own server room for housing servers and network devices.How the two activities being executed? Explain the difference between 'y' and "xy" when used as constants in C. Describe the memory representation of both values. [5 marks] (b.a) Consider the following C program: void swap(int x, int y) { int temp = x; x = y; y = temp; } int main(int argc, char **argv) { int x = 0; int y = 2; swap(x, y); assert(x == 2); return 0; } Briefly explain the role of the assert statement and why this program will trigger an assert failure when executed. Supply two modified versions of the program that alter the swap function definition and, if necessary, its calls, to avoid this assert failure. One version should be in C, and the other should use C++ language features. [5 marks] This is their main selling point. However, ray tracing is so computationally intensive that it is not possible to produce images at the same speed as hardware assisted polygon scan conversion. Other researchers are trying to this by using multiple processors (dozens to hundreds), but ray tracing will always be slower than polygon scan conversion. Ray tracing therefore is only used where the visual effects cannot be obtained using polygon scan conversion. This means that it is, in practice, used by a minority of movie and television special effects companies, advertising companies, and enthusiastic amateurs. 1.1.2 Example The kitchen in Figure 2 was rendered using the ray tracing program Rayshade3 . Rayshade has not been updated for over a decade. An alternative ray tracer, which is kept up to date, is POVray4 , with which you may like to experiment. It is worth visiting the POVray website to see the stunning imagery which has been produced using the ray tracer . The close-ups of the kitchen scene in Figures 3 and 4 show some of the power of ray tracing. The kitchen sink reflects the wall tiles. The bench top in front of the kitchen sink has a specular highlight on its curved front edge. The washing machine door is a perfectly curved object (impossible to achieve with polygons). The inner curve is part of a cone, the outer curve is a cylinder. You can see the floor tiles reflected in the door. Both the washing machine door and the sink basin were made using CSG techniques (see section 8.2). The grill on the stove casts interesting shadows (there are two lights in the scene). This sort of thing is much easier to do with ray tracing than with polygon scan conversion. 2http://www.artvps.com/ 3http://graphics.stanford.edu/cek/rayshade/rayshade.html 4http://www.povray.org/ 6 Advanced Graphics Lecture Notes Figure 2: A ray traced model of a kitchen design.

The term scan comes from the fact that an image on a CRT is made up of scan lines. Then can utilize JavaFX to add a graphical UI (GUI) to the game, which shows the 2D board and permits the client to play the game. Should utilize JavaFX, no other Java GUI libraries. Questions: Question 1: Make a Data Design Decisions: Think cautiously about whether every cell in the guide ought to be a crude esteem (like a number or an enum esteem), or would it be a good idea for it to be an article? Utilizing objects is more adaptable, since it permits to utilize Java subtyping to cause various cells to have different way of behaving. Question 2 Impleent and Test the Game Engine: GameEngine.java is given as the base to motor turn of events. Need to add more subtleties to it, and may likewise need to add other class records in the "savemonkeys.engine" bundle to help the motor turn of events. TDD is suggested, yet excessive, to foster unit tests and game motor at that point, in equal. Review: Design a test for each new component and make sure that it falls flat, then, at that point, carry out that element in the motor classes and rerun the test to make sure that it currently passes. Rehash... can refactor (rename and rearrange) the code at any stage, if see an approach to simplifying it and more exquisite. When have wrapped up carrying out the game motor, one (or a few) of tests ought to venture through a total game from begin to end, calling the strategies for your motor API and really looking at the outcomes, including the game dominate/lose decision toward the end.
