<<<<<<< HEAD cs795-pa1

Part #1:

Total Points: 100

Objective: Write a program that reads in Obj file and output the mesh into Euler operators

Steps: Here are the steps that you should follow in order to finish this part of the project

#1: Read how triangle mesh are organized (objviewer/model.*)

#2: Familiar yourself with Euler Operators:

Here are the 8 Euler operations that you will see in the code.
They also correspond to the Euler operations that you will
write to the file. 

/*Make vertex face solid*/
mvfs(Id s,Id f,Id v,double x,double y,double z)

/*Kill Edge Face*/
kef(Id s,Id f,Id v1,Id v2)

/*Make edge vertex from half_edege_1(v1,v2) in f1 to half_edege_2(v1,v3) in f2*/
mev(Id s,Id f1,Id f2,Id v1,Id v2,Id v3,Id v4,double x,double y,double z)

/*Kill edge&vertex*/
kev(Id s,Id f,Id v1,Id v2)

/*Make edge face from half_edege_1(v1,v2) in f1 to half_edege_2(v3,v4) in f2 , he1 in the new face*/
mef(Id s,Id f1,Id v1,Id v2,Id v3,Id v4,Id f2);

/*Kill edge make ring*/
kemr(Id s,Id f,Id v1,Id v2)

/*Make Edge kill Ring*/
mekr(Id s,Id f,Id v1,Id v2,Id v3,Id v4)

/*Make face , kill ring & hole*/
mfkrh(Id s,Id f1,Id v1,Id v2,Id f2)

Example: cube.gwb

mvfs 1 1 1 -100 -100 -100
mev 1 1 1 1 1 1 2 100 -100 -100
mev 1 1 1 1 2 2 3 -100 100 -100
mev 1 1 1 3 1 1 4 100 100 -100
mef 1 1 2 1 4 3 2
mev 1 2 2 1 3 3 5 -100 -100 100
mev 1 2 2 2 1 1 6 100 -100 100
mev 1 2 2 3 4 4 7 -100 100 100
mev 1 2 2 4 2 2 8 100 100 100
mef 1 2 6 2 5 1 3
mef 1 2 5 1 7 3 4
mef 1 2 7 3 8 4 5
mef 1 2 8 4 6 5 6

#3 Read Euler_Primitives.cpp to understand how the primitive shapes are created.

#4 Implement a method that converts "struct model" in model.h to a list of Euler operators

#5 Verify your results by comparing them visually using gwb and objview
