## Summary

Create a vdPolyface with material image and mapping TexCoords

## Solution

Example:

```Suppose we have create an image 'textcoords.png' looks like
with widthxheigth = 2598x1732 (aspect width/height = 1.5)

Following a code that create a new vdPolyface that represent a box 1x1x1 size
and maps  the parts of the image to each face
NOTE: Assume the image coords to be lowerleft = 0,0 and upperright = 1,1
//points of a box corners
gPoints pts = new gPoints();
//bottom points
//top points
Int32Array facelist = new Int32Array(new int[] {
//note: change the
1,2,3,4,-1,//bottom
5,6,7,8,-1,//top
1,2,6,5,-1,//front
3,4,8,7,-1,//back
4,1,5,8,-1,//left
2,3,7,6,-1,//right
});

//NOTE: Assume the image coords to be lowerleft = 0,0 and upperright = 1,1
//--->(texture coords relative to the image lower - left)
//  0.0  0.33 0.66 1.0
//
//1  |----|----|----|
//   |-A--|-B--|-C--|
//0.5|----|----|----|
//   |-D--|-E--|-F--|
//0  |----|----|----|

DoubleArray texcoords = new DoubleArray(new double[] {
0.0,0.5,0.33,0.5,0.33,1.0,0.0,1.0,  //bottom  A letter
0.33,0.5,0.66,0.5,0.66,1.0,0.33,1.0,//top    B letter
0.66,0.5,1.0,0.5,1.0,1.0,0.66,1.0,  //front  C letter
0.0,0.0,0.33,0.0,0.33,0.5,0.0,0.5,  //back   D letter
0.33,0.0,0.66,0.0,0.66,0.5,0.33,0.5,//left   E letter
0.66,0.0,1.0,0.0,1.0,0.5,0.66,0.5,  //right  F letter
});
vdPolyface pf = new vdPolyface(doc, pts, facelist) { TexCoords = texcoords };
vdColor pfcolor = new vdColor(Color.Blue);
