Interpolations.cpp
by Josh Allen
Designed with Dev-C++ v. 4.9.9.2

This program uses the same framework for Homework 1.  That being said,
you can use these keys to transform the object while it is not in motion:

KEY	TRANSFORMATION
--------------------------------------------------------
R	Rotate object around x-axis
F	Rotate object around y-axis
V	Rotate object around z-axis
T	Translate along x, positive direction
G	Translate along y, positive direction
B	Translate along z, positive direction
Y	Translate along x, negative direction
H	Translate along y, negative direction
N	Translate along z, negative direction

In order to view the interpolations, press one of these keys:

KEY	INTERPOLATION
--------------------------------------------------------
F1	linear interpolation, constant speed
F2	linear interpolation, ease-in/ease-out
F3	Catmull-Rom spline interpolation
F4	B-Spline interpolation

The values for the vertex positions and orientations are hard-coded in
the program.  To change them, look at the fillFramesMatrix method and
the fillAnglesMatrix method at the end of the file.  The matrices are
6x3, one row for each frame, one column for each coordinate.  The time
step depends on the variable "steps" on line 55; it specifies the number
of frames between each keyframe.

All of the interpolation calculations will be found within the
interpolation method.  However, a small piece of code associated with
orientation (conversion from quaternion to angle-axis) is found in
the display function.

NOTE:  this program was created with a predefined matrix class called
apmatrix; the necessary files are included.
