Background: NVIDIA RTX graphics hards have Help for an information construction known as a Bounding Quantity Hierarchy, or BVH for brief. It’s basically simply rectangles within rectangles… that is it. The larger rectangles are used to rapidly reject collisions and tracelines – if a line does not cross the large rectangle, then it may’t intersect any of the rectangles inside it. In case you’re intelligent when constructing your BVHs, this lets you rapidly decide what rectangle is hit by what ray, and therefore can do ray tracing in actual time. We’re not doing ray tracing graphics for this task, we’re simply going to construct a BVH, and do a bunch of fascinating issues with it, reminiscent of validating that the map information is right, and seeing which crates in a warehouse get shot probably the most. This can be a greenfield task, which means you are given no Makefile, and mainly an empty predominant.cc. You might be chargeable for creating courses (utilizing correct class design) for a Ray class, a Rectangle class, a Level class, and anything you may consider, and splitting the challenge into totally different .h and .cc recordsdata, and utilizing a Makefile you write to construct the challenge. I’ve pattern Makefiles in /public, and I even have some hints (primarily within the type of feedback) in /public/rtx_on/hints.cc that may offer you some concepts. However I like to recommend making an attempt to do the challenge with out the hints as a lot as potential. As soon as throughout the challenge, you may inform me “The Beacons are lit. Gondor requires help.” and I will offer you a related code snippet that you need to use in your challenge. Use this in the event you get caught. There’s numerous simple level pickups from doing issues like error checking and map validation, so even in the event you do not suppose you’re going to have the ability to end the challenge, you need to a minimum of begin the challenge and get as many factors as you may. You would possibly discover it will get simpler when you get into the groove. As at all times, do not wait to the final minute to begin the challenge. Begin early so you may ask for Help early. ============== The Map Format ============== The map file holds a bunch of rectangles. A few of the rectangles are strong, and you’ll consider them like crates in a warehouse. They are often enclosed by a non-solid rectangle, and people rectangles are simply there to make the intersection testing and such go sooner. If a line does not cross a non-solid rectangle, then it can’t hit any rectangle inside it. Good! The format is: Stable(1)/Nonsolid(zero) x_min y_min x_max y_max (checklist of kids iff not strong) The checklist of kids are line numbers (the traces begin at zero) of strong rectangles contained in the non-solid rectangle. Stable rectangles should not have youngsters. All non-solid rectangles will need to have youngsters. Here is a pattern file: zero zero zero 100 100 1 2 1 1.1 1.zero 1.2 1.three 1 10 10 11 11 zero 50 60 70 80 Four zero 55 65 65 75 5 1 56 66 64 74 The primary line (line zero) is a non-solid rectangle with two youngsters (the following two rows, traces 1 and a couple of). The primary rectangle ranges from (zero,zero) to (100,100). The kids of it are each small strong rectangles, the primary is simply .1 x .three, starting from (1.1,1.zero) to (1.2,1.three) and the second is just one x 1, starting from (10,10) to (11,11). The fourth line (line three) is a second non-solid rectangle. This one comprises solely a single non-solid rectangle, and that one comprises a single strong rectangle. Attainable errors: 1) A non-solid rectangle has no youngsters (having a non-solid baby is okay) 2) A minimal worth is >= the utmost worth (so if the minimal x is 10, the utmost x cannot be 9, and so forth.) three) A baby of a rectangle stands out from the mother or father rectangle (all youngsters should be fully enclosed by the mother or father) ========== Photographs File The pictures file holds a listing of pictures (think about some hitscan weapon in a online game like a shotgun or one thing). Every shot has an origin and a course. The origin is an (x,y) coordinate, like (5,three). The course is a slope and whether or not the shot is touring alongside that slope or within the reverse. A slope of “Vertical” signifies that the shot is travelling straight up and down. The format is: x_location y_location slope(both a quantity like 2.1 or a non-number which means “Vertical”) forwards(1 which means forwards, zero which means backwards) zero zero zero zero zero zero zero 1 zero zero Vertical zero zero zero Squirrel 1 10 10 -1 1 -10.1 -100.01 2.1 zero The primary line is a horizontal line capturing left from the origin (zero,zero). The second line is a shot additionally travelling horizontally from the origin, however ahead alongside the x axis as an alternative of backwards. The third line is capturing straight down out of the origin The fourth line is capturing straight up out of the origin (any non-number means Vertical, not simply Vertical) The fifth line is travelling diagonally down and to the suitable out of (10,10) The sixth line is travelling steeply (slope: 2.1) down and to the disregarded of (-10.1,-100.01) Issues to be careful for: be sure you can deal with unfavorable slopes in addition to non-numbers (like “vertical” or “squirrel” or “-“) which all imply the shot is vertical. ================== Menu of Operations ================== You begin off by printing an RTX banner with figlet, after which load a map file and a pictures file. If there’s any errors in these recordsdata (like a min worth being >= a max worth) give up instantly. Then print this: 1) Print the world of bins 2) Print the checklist of pictures three) Verify the bins for correctness Four) See if two rectangles overlap 5) See if a ray hits a rectangle 6) Output a listing of all strong bins colliding 7) Hearth all pictures and see which field is getting hit probably the most Please enter alternative: You will need to implement every of the 7 operations, however in the event you do not wish to do all of them and are high-quality with not a 100%, then I might implement them so as, as I kind of ordered them by problem. Every operation runs as soon as after which quits. Whereas inconvenient, it makes it simpler so that you can choose up extra factors in take a look at circumstances. === Operation 1 – Print the map information === For the pattern map above, it could appear to be this: (zero.00,zero.00) to (100.00,100.00) NOT SOLID Kids: 1 2 (1.10,1.00) to (1.20,1.30) SOLID (10.00,10.00) to (11.00,11.00) SOLID (50.00,60.00) to (70.00,80.00) NOT SOLID Kids: Four (55.00,65.00) to (65.00,75.00) NOT SOLID Kids: 5 (56.00,66.00) to (64.00,74.00) SOLID (NOTE THAT ALL NUMBERS ARE ROUNDED TO EXACTLY TWO DECIMAL PLACES ALWAYS) === Operation 2 – Print the shot information === For the pattern pictures file given above, it could print out this: (zero.00,zero.00) Slope: zero.00 Backwards (zero.00,zero.00) Slope: zero.00 Forwards (zero.00,zero.00) Slope: Vertical Backwards (zero.00,zero.00) Slope: Vertical Forwards (10.00,10.00) Slope: -1.00 Forwards (-10.10,-100.01) Slope: 2.10 Backwards === Operation three – Map Verify === It is pretty frequent to have recordsdata containing information, and for packages who load the info to not do numerous checking at load time for pace causes. However they nonetheless should be checked to verify they do not include errors, so possibly the map making device or a separate mapcheck device would possibly exist to search for errors. On this case, it’ll search for any rectangles that stretch out of their mother or father rectangle. For instance, in the event you had this file zero 10 10 20 20 1 1 15 15 25 25 This is able to have a mother or father rectangle from (10,10) going to (20,20) but it surely’s baby goes from (15,15) to (25,25), which means it’s not enclosed by the mother or father rectangle. This defeats the entire level of a BVH, which is to make intersection assessments with giant numbers of rectangles quick by enclosing them in a rectangle. If any stick out, then it simply does not work. Your code ought to print: Map Appropriate if the map is right, or Map Error: Field 1 if the map has an error. Stop on the primary baby rectangle that stands out from a mother or father. The field quantity is its line within the file (traces begin at zero). === Operation Four – Rectangle/Rectangle Intersection === This operation does not use the maps file. You simply manually enter two rectangles and it tells you in the event that they intersect or not. It is designed to allow you to take a look at your algorithm to see if two rectangles intersect. Instance: Please enter the min and max factors for a Rectangle (instance: zero zero 10 20 to make a field from (zero,zero) to (10,20)): zero zero 10 10 After which once more for a second Rectangle: 9.9 9.9 10.1 10.1 They intersect! Instance 2: Please enter the min and max factors for a Rectangle (instance: zero zero 10 20 to make a field from (zero,zero) to (10,20)): -10 -10 -5 -5 After which once more for a second Rectangle: -Four -Four 10 10 They do not intersect === Operation 5 – Ray/Rectangle Intersection === That is much like #Four besides you are testing to see if a Ray hits a Rectangle. Instance: Please enter the min and max factors for a Rectangle (instance: zero zero 10 20 to make a field from (zero,zero) to (10,20)): 5 1 6 100 Please enter a shot (for instance: zero 5 1.1 1 means it comes from (zero 5) heading up at a slope of 1.1 within the forwards course): zero three 5 1 HIT! Location: (5.00,28.00) Instance 2: Please enter the min and max factors for a Rectangle (instance: zero zero 10 20 to make a field from (zero,zero) to (10,20)): -10 -10 -5 -5 Please enter a shot (for instance: zero 5 1.1 1 means it comes from (zero 5) heading up at a slope of 1.1 within the forwards course): -Four -9 2.1 1 MISS! === Operation 6 – Collision Detection === This one is simply Operation Four, however throughout the entire map. For all strong rectangles on the map, you output all the opposite strong rectangles it’s touching, if their row quantity is greater. Instance Map File: zero zero zero 100 100 1 2 three Four 5 1 1 1 2 2 1 10 10 11 11 1 1 30 31 60 1 90 zero 100 10 1 -100 -100 100 100 1 99 99 101 101 Instance Output: Field 1 and Field 5 intersect. Field 2 and Field 5 intersect. Field three and Field 5 intersect. Field Four and Field 5 intersect. Field 5 and Field 6 intersect. If there are not any intersections it prints “No bins overlapped!” === Operation 7 – Photographs Fired === This one is simply Operation 5, however throughout the entire map. For all pictures within the pictures file you see which field acquired hit within the maps file. The field that acquired hit probably the most you print: Field three acquired hit probably the most And give up. That is it! Good luck! Have enjoyable!
