Animating the Head

I came up with a very simple idea to animate the head. The animation features a polo flying around the the head model, with the eyes of the model watching it before the model then opens his mouth and puts his tongue out, where the polo then lands and ends with the head swallowing the polo.

This was quite a simple animation to produce, with the rotation tool used for the movement of the eyeballs and the morpher modifier used for the opening and closing of the mouth. The polo simply moves by changing the position for certain keyframes.

The morpher modifier allowed me to create realistic mouth movement by cloning the head, moving the vertices of the mouth to an open position on one model and a closed position on the other model and filling the gap for me.

Adding Hair

To create the hair, I simply highlighted the faces on the top of the head that needed hair applying and added the hair and fur modifier. This was the first time I'd ever used the hair and fur modifier in 3D Studio Max.

I chose a pre-set option for the colour of the hair and, although a little light, I think it was the closest option to my actual hair colour.

To achieve the correct style was a matter of cutting the hair, re-combing it into place to follow the faces of the head and then use the brush tool to sweep it aside at the front.

I found that the hair took the longest time to render, and would only render in perspective mode. However, this was not a problem in the end and the addition of hair made the model look far more realistic.

UVW Mapping and Skin Textures

This was the most difficult part of the creation of the head model. I began by adding an unwrap UVW modifier onto the head model and placing the cylindrical gizmo over the head. Then, after adding a checkered material to the head I began editing the UVWs in order to give a smooth material. By selecting trouble areas of vertices I could use the relax tool in order to try to alleviate the problems. I found this quite hard to do, possibly due to some troubles with model structure around the side of the head.

The next task was to use pelt mapping in order to solve the UV problems of the ear. By moving and scaling the stretcher, and then pulling the strings into the correct direction, I could simulate pelt pulling in order to pull out the vertices of the ear. by now the shape of the UV points was too large, so I had to scale the ear down to the correct size.

Having now got one side of the face and one ear complete, I could simply mirror these across to give the full UVW-mapping of the face and then render the UVW map.

The next stage was to create a skin texture in Adobe Photoshop CS5, using this UVW map as a guide. I am fairly confident with Photoshop and managed to create a reasonably good skin texture here, cutting and pasting sections of skin from the reference photos into the right places.

After this was finished, a bump map was also created in Photoshop. this was done in order to bring out more detail in the skin. In 3D Studio Max, it was then a case of creating a suitable material, using the mix option in the material browser to create a suitable blend of the skin map and bump map in order to bring out maximum detail in the skin

I did have a lot of trouble with the UVW mapping part of this assignment. The final result wasn't brilliant and there are a lot of areas which could be improved. I believe the Photoshop work went fairly well, the problems were caused in UVW-mapping in 3DS Max (and possibly stemmed from structure problems). This is something that I will definitely need to work on.

Eye and Eyelash Creation

In order to make the eyes, I began by going to the extended primitives menu and creating a capsule. I converted this to an editable poly and removed the middle ring of faces, joining the two sides left to form a rough sphere shape. I then cloned this shape by holding down shift and using the scale tool.

I applied a MeshSmooth modifier and on the outer sphere pulled the vertices at one end to give a slight bulge shape. On the inner sphere I pushed in the vertices of one end in order to flatten that end. I now had a basic eyeball. On the inner sphere I could apply the eyeball texture, whilst I made the outer sphere of a water material in order to give the eyes a wet look.

The next step was to create the eyelashes. I did this by creating a few different spline curves and extruding thin cylinder shapes along these splines. I then changed the taper parameter so that the cylinders grew thinner towards the end.

In order to fit these eyelashes I simply cloned lots of cylinders and placed them around the eyesocket. In the final render the eyelashes aren't that noticeable, however they do give crucial detail to the eye area of the model.

Ear Creation

To create the ear I began in the same way as I had created the face - by using the reference planes to lay out quads and then pull the vertices out in order to make the shape 3-dimensional. However, the ear is a very complex shape and I found this more difficult to model than the face.

One tool that came in very useful in modelling the ear was the chamfer tool. This enabled me to create better canals in the ear and achieve a more organic shape. Once again, the use of the TurboSmooth modifier allowed me to smooth the ear into a better finish.

I also found it quite hard to attach the ear. As with the back of the head, this was done using the weld and target weld tools. I started this process by removing faces from the head. I then created some new faces on the ear which could be used to join to the head.

In the end I think I achieved quite a good ear design. It does look slightly rigid and could be improved in the future for a more organic look, however the overall shape is quite well designed.

Creating the back of the head

In order to create the back of the head, I began by creating a standard sphere primitive. I then converted this into an editable poly and took out the bottom half of the sphere. Now I could use the reference planes to line-up this editable sphere poly and then pull the edges and vertices around in order to better shape the head. Once the head was the correct shape, the use of the weld and target weld options enabled me to join the head to the face.

I found most of this part of the head reasonably simple to model. However, one area that was a bit more tricky was the sides of this shape. Since I had earlier deleted the middle faces of the sphere, it was hard to join these correctly. Once completed, I again used the TurboSmooth modifier to give the shape a very smooth finish.

The Symmetry Modifier

In order to duplicate the topology that I had already created over to the other side of the face I used the symmetry modifier. By moving the mirror plane around, I could achieve the correct mesh. It was then simply a matter of dropping down into editable poly mode whenever I needed to edit part of the face and the modifications would then automatically reflect over through the symmetry modifier.

Once the symmetry modifier was applied, I also applied the TurboSmooth modifier. This was used in order to obtain a nice smooth finish as the shapes created earlier made for a very low-resolution face.
