Subject: sp5 solution components

(This message is being sent to CPSC 215 Students and TA's)

I have placed 3 components of the solution to sp5 in the sp5data
directory.

sp5sphere.c - contains the complete code for sphere_init() and
              sphere_dump()

sp5vec.c    - contains vl_get3() and vl_vecprn3() readers and
              writers of three component vectors

sp5mat.c    - material loader and dumper

sp5obj.c    - object constructor

--------------------------------------------------------------
as far as I can tell that leaves only the plane_init() and
plane_dump() functions which are clones of their sphere
counterparts to be written.   I believe almost EVERYTHING else
is available as a solution. (You will have to write vl_get1()
and vl_vecprn1() if you use my sphere initializer.

---------------------------------------------------------------

So if you still don't have a working sp5 here is what to do:

(1) assemble the components from the various solution directories
    into an sp5 directory

(2) comment out the plane_init() and plane_dump() calls in model.c

(3) add vl_get1() and vl_vecprn1() to veclib()

(4) make sure prototypes of ALL FUNCTIONS are in rayhdrs.h

(5) try to build

(6) delete the planes from sp5.txt and try to run

(7) using the sphere as a guide, write the plane functions

(8) run sp5a.txt sp5b.txt and sp7c.txt

If you get stuck at ANY POINT in this process,  contact me or the
TA SOONER rather than LATER.

----------------------------------------------------------------

It should be obvious that until you can come up with an operational
model loader NOTHING ELSE WILL WORK! Thus the ONLY choices are:

(1) get it working
(2) drop the course
(3) take an F
