CISC/CMPE 454 Assignment 3

 CISC/CMPE 454 Assignment 3

 
Your task is to implement a roller coaster simulator.  You may work in
groups of two, except that grad students must work individually.
 
On Linux and MacOS, run the program as
 
  ./roller data/coaster1.txt
 
On Windows Visual Studio, include "data\coaster1.txt" in the Debugging
command-line arguments.
  
After the program starts, press '?' in the window to print a list of
available commands.
 
Do the following:
 
1. Implement Spline::eval() to evaluate the spline at a given
   parameter value.  Note that the function can return the value or
   the derivative. [6 marks]
 
2. Implement Spline::findLocalSystem() to return a local coordinate
   system at a given parameter value.  This coordinate system is quite
   important: it is used to draw the track and to position the train
   on the track.  Use the derivative from Spline::eval(). [2 marks]
 
3. Implement Train::draw() to draw at least one train car at the
   current position.  Start with a simple box, then improve it.  It's
   easiest if you create a Cube class (like the Sphere and Cylinder)
   and then instantiate a scaled cube for the box.  [4 marks]
 
4. Implement Train::advance() to move the train along the track.  This
   function adjusts 'pos' and should vary the speed ACCORDING TO SOME
   PHYSICAL MODEL.  Start with a constant speed, then add the
   physics. [4 marks]
 
5. Implement Scene::drawAllTrack() to draw tracks in place of the
   spline curve.  Choose your own way of drawing the tracks.  Start
   with a very simple smooth surface, then improve it to have two
   rails.  Then add ties between the rails.  [6 marks]
 
6. Create a novel roller coaster scene.  You should use a different
   terrain than the one provided.  You may use heightfields and
   matching textures from other sources.  Show an interesting
   track. [1 mark]
 
7. Add some novel features of your choosing [5 marks].  Some
   possibilities are:
 
     - Have multiple connected cars that can bounce around slightly
       independently, but remain connected.  Worth up to 3 marks if
       done well, 1 mark if done without much novelty.
 
     - Have a mode in which the viewpoint moves with the train.  Worth
       up to 3 marks.
 
     - Add support structure under the tracks.  Worth up to 4 marks if
       done well.
 
     - Add a parameter at each control point to let you control the
       tilt of the track at that point.  Show the tilt and provide a
       handle so that it can be edited with the mouse.  Use it when
       computing the local coordinate system.  This lets you make
       loops.  Worth up to 5 marks.
 
     - Have a section of track that lifts the cars to the top and then
       releases them.  Animate the lifting mechanism.  Worth up to
       5 marks.
 
     - Add a feature to import and position objects.  The objects
       should be in a common format (e.g. STL or Wavefront) and should
       be specified in the scene file, along with its position and
       orientation in the world.  This is how you get the roller
       coaster to go through a tunnel or how you get a triceratops on
       your terrain.  Worth up to 4 marks.
 
     - Populate your terrain with trees that are *procedurally*
       generated at run-time.  Worth up to 5 marks.
 
     - Ask the instructor what other features could be worth.
 
8. Submit a single archive.  That archive must be contain all files
   within a directory named (lowercase) a3.  The files in the a3
   directory must be
 
     README.txt - containing names and netIDs of the one or two
                  persons who did the assignment,
 
                  and a short description of the feature(s) that you
                  implemented,
 
                  and a short description of the physical model you
                  used to advance the train.
 
     1.png, 2.png, 3.png, ...  - at least one screenshot of your
                                 completed assignment showing your
                                 novel feature(s).  More than one
can be provided if you wish.
 
     *.cpp and *.h - ALL of the *.cpp and *.h files from the 'src'
                     directory, even if you did not modify them.  The
                     TAs will compile only the files that you submit.
                     If you created new source files, include them
                     here.
 
   -1 if these instructions are not followed exactly.
