    MDD file format

The MDD file format is very simple and here is a brief description for TD's and developers
who are interested in adding tools to a pipeline built around MDD.
The first thing to note is that the MDD file format is Motorola Big Endian byte order
as opposed to the Intel Little Endian standard. So however you implement the structure
below, you must come up with an algorithm to flip the bytes during file IO.
The data structure is:
typedef Struct{
  int totalframes;
  int totalPoints;
  float *Times; //time for each frame
  float **points[3];
}mddstruct;

and the data is written:
totalframes
totalPoints
Times

while(!totalframes){
  while(!totalPoints){
    write point[frame][point][axis];
    point++;
    }
  frame++;
}
