Head Modelling Tutorials

We were shown these maya tutorials in class on how to model a head in the correct way and hopefully avoid triangles forming. There was also the Thunder Cloud Studios article on how to model a realistic human head with helpful advice on how the edge loops are placed.

Head Drawing Research

How to draw the human skull

This wasn’t actually helpful for the task, but as usual with youtube I was distracted by little thumbnails and I figured this would be a fun little thing to watch, and it was.

I found that this video was a bit rushed when trying to show the different steps of the drawing, as it would jump ahead and not really let you see what was done. However, I did up with a version I was happy with as I was drawing along with the video.

I found this to be more helpful in explaining the different steps of the drawing, what the basic shapes where and how you build upon them.

How to draw a portrait

I could never draw portraits before watching this video and after a this I ended up with a drawing that actually resembled the Andrew and not the creature from the Goonies. I had always tried to start with a clear outline of the facial features and work from there rather than starting light and using shading to bring out the different features. These three videos were really, really helpful.

Head Reference Images

I had to get pictures of Andrew’s head for reference when I come to model it. Initially I was just going to have him stand there and take the pictures but we found out he is just too tall for me to reach. So, he sat down to make it easier for me- and was still taller. However, the height difference was significally decreased so I got the photos.

Next I’ll draw on the various facial muscle groups onto the photos so it will be easier to edge loop in Maya.

Modelling- In Progress

After modelling an arm in class, I decided to try and model a person and found the image below online.

I’m not entirely sure how I found this image, I can’t find it again even though I used the same search words, but I’ve tried to model it.

I started with the arm since we did a version of it and when I went to extrude the hand I had accidentally selected the vertices rather than the faces, but it’s an interesting result. Matthew said it reminded him of the Iron Man suit.

Crime Chart

I read Visual complexity and liked the radial organisation chart, and decided to try and replicate it with the data we found on crime statistics that I got from the PSNI website. (In order to get the figures for crime in the city of Belfast I had to draw out the boundary of the city on the interactive map, and then it gave me the data.)

How I made it:

The circles are all actually to scale. I used Maya, created NURB circles and scaled them up to the percentages of each individual category of criminal activity that was conducted. Then I took a screenshot and drew over the image in Illustrator.

The five coloured circles represent the different types of crime and then the smaller, fainter coloured circles, represent the specific crime committed.
