For assignment 1 of creative strategies we have been given the task to animate a walk cycle using an already rigged 3D character. Before I started animating I wanted to do research on how people walk. Everyone walks differently, its like our own finger print. People come in all different shapes and sizes and this also makes a great effect on how people walk.
The following is a 500 word essay that I did last year when researching drawing with weight in life drawing class. I thought it was relevant looking back as it is on how gravity effects a person depending on their mass:
The first thing that I had to consider was what is gravity and how can it effect a form? Gravity is the force that attracts a body towards the centre of the earth. Unless you are in space with no gravity, you must illustrate with weight in mind. Mass is just one component that gives a 2D drawing a more 3D feel. There are several things to consider when drawing. These include the scale, weight, mass and density. Mass multiplied by gravity equals weight. Weight in mass is density. The denser the object the more mass it has meaning more gravity is implied upon it. With these in mind we can make our drawings more believable and alive.
Below is a YouTube tutorial video of animation walk cycles. It explains the different type of walk cycle steps and gives good advice on how and when to create the poses.
