1. myply.h:  replace the myPlyVertex definition with:

typedef struct myPlyVertex {
  Dbl x;
  Dbl y;
  Dbl z;
  Dbl u;
  Dbl v;
  int r;
  int g;
  int b;
  Dbl nx;
  Dbl ny;
  Dbl nz;
} myPlyVertex;

1. myply.h: change numVertexProperties from 6 to 8 and replace vertex_property declaration with:

static struct PlyProperty vertex_property[8]= {
 {"x",0,Float64,0,0,0,0,0},
 {"y",0,Float64,sizeof(Dbl),0,0,0,0},
 {"z",0,Float64,2*sizeof(Dbl),0,0,0,0},
 {"texture_u",0,Float64,3*sizeof(Dbl),0,0,0,0},
 {"texture_v",0,Float64,4*sizeof(Dbl),0,0,0,0},
 {"color_r",0,Int32,5*sizeof(Dbl),0,0,0,0},
 {"color_g",0,Int32,5*sizeof(Dbl)+sizeof(int),0,0,0,0},
 {"color_b",0,Int32,5*sizeof(Dbl)+2*sizeof(int),0,0,0,0},

};

1. Mesh.h: add the following definition:

void getTextureCoord(int vNum, Dbl *texture);

1.  Mesh.cpp: add the following routine

void Mesh::getTextureCoord(int vNum, Dbl* texture)
{
 if (vNum < 0 || vNum >= thePlyMesh.numVertices) {
  printf("Invalid vertex number.\n");
  return;
 }
 *texture = thePlyMesh.theVertices[vNum].u;
 *texture = thePlyMesh.theVertices[vNum].v;
 return;
}

1. Use the code from project 2 to read in the texture map.

1. Report any difficulties to me.
