Let me know if more debug points or values would be useful! egoode6@gatech.edu
To print out instances of your classes, you will need to define a __repr__ method on the class. For example, for the Hit class:
def __repr__(self):
return "Hit(t=%f, intersection_point=%s, intersected_shape=%s, normal=%s)" % (self.t, self.intersection_point, self.t_shape, self.normal)
Correct images (triangle intersections, no ambient, no specular, no shadows, no reflections)
Place the following code at the top of your triangle intersect function. Change variable names as needed.
if debug_flag:
print "testing intersection with triangle whose color is ", self.mat.dif_color
Then, after you compute t:
if debug_flag:
print "ray direction: ", ray.dir
print "normal vector: ", self.normal
print "plane intersects at at t=%f" % t
Then, after computing the triple products:
if debug_flag:
print "triple 1: ", triple_1
print "triple 2: ", triple_2
print "triple 3: ", triple_3
