Subject: SP2 sample output

(This message is being sent to all CPSC 102 Sec 1 students )

Whenever plane_hits or sphere_hits returns -1.0 the "hitpoint
location" should be considered meaningless.

It appears that I changed the test driver after I computed
the sample output by inserting these

   memset(obj1->last_hit, 0, sizeof(vec_t));


Hence if your output differs from mine only in the "hitpoint"
when dist is -1  DON"T WORRY ABOUT IT...

dist to plane 1   12.000

hit point    4.000    3.000   -7.000

dist to plane 2   15.000

hit point    4.000    3.000  -10.000

positive z test

dist to plane 2   -1.000

hit point    0.000    0.000    0.000

vertical ray test

dist to plane 1   -1.000

hit point    0.000    0.000    0.000
