1. A method of determining a pose of a model in a computer graphics system wherein the model is storable in electronic storage and usable in a process for generating imagery corresponding to the model, the method comprising: receiving a current pose attribute of a pose degree of freedom of the model; determining a first measurement comparing the current pose attribute of the pose degree of freedom of the model with a deep pose; determining a second measurement comparing an attractor pose attribute of the pose degree of freedom with the deep pose, the attractor pose attribute of the pose degree of freedom is indicative of an attribute of a pose to which the model is attracted to at any given moment; determining whether the current pose attribute of the pose degree of freedom of the model is more similar to the deep pose than the attractor pose attribute of the pose degree of freedom based on the first and second measurements; and in response to a determination that the current pose attribute of the pose degree of freedom of the model is more similar to the deep pose than the attractor pose attribute of the pose degree of freedom: 1) modifying the attractor pose attribute of the pose degree of freedom based on at least the current pose attribute of the pose degree of freedom of the model; and 2) determining a pose attribute of an additional pose degree of freedom based on the modified attractor pose attribute of the pose degree of freedom.
