As you can see from the image above, I have now created a surface for the topology lines and in effect creating a 'half mask' which is a 2D image that will eventually be manipulated into a 3D image. To create this, I selected one of the squares that I had made, then right-clicked and converted it to Editable Poly. This then converted it from a square to a surface, giving me a filled polygon. Then, using the 'attach' tool, I was able to select all of the other lines/polygons on my image and attach them to the first polygon that I created so that all of the other polygons became coloured (contain a surface). Using the 'edged faces' tool, I could then view the lines as well as the surfaced mask.
Finally, I had to weld my polygons together so that they no longer moved individually but all move as one object. To do this, I first selected every individual moveable point (corners of polygons) and used the snap tool to position the points on top of each other. Then I joined the points together using the weld tool, which enabled me to convert the various polygons into one moving object. Now, when I drag the corner of a polygon, the adjoining polygon also moves. This shows that the entire 'half mask' is now all linked together and moves as one.
Now that this stage is complete, I can finally start to see my image taking effect and although it is not currently 3D, I can see now how it will become 3D and how I am progressing towards a resemblance of my face.
I encountered some problems with this stage of the process. The biggest problem was trying to weld the vertices together. Some of them did not weld as I intended. To overcome this, I simply selected the individual points that I wanted to weld, then increased the weld threshold which then welded the points together. I found the nostril, corner of the mouth and the eye very difficult to draw polygons around, especially without creating any triangular shapes. I managed to avoid all triangles/five sided shapes eventually, mainly by trial and error until I found the best fit for the various polygons.
