Senescence: An Aging based Character Simulation Framework

The \u27Senescence\u27 framework is a character simulation plug-in for Maya that can be used for rigging and skinning muscle deformer based humanoid characters with support for aging. The framework was developed using Python, Maya Embedded Language and PyQt. The main targeted users for this framework are the Character Technical Directors, Technical Artists, Riggers and Animators from the production pipeline of Visual Effects Studios. The characters that were simulated using \u27Senescence\u27 were studied using a survey to understand how well the intended age was perceived by the audience. The results of the survey could not reject one of our null hypotheses which means that the difference in the simulated age groups of the character is not perceived well by the participants. But, there is a difference in the perception of simulated age in the character between an Animator and a Non-Animator. Therefore, the difference in the simulated character\u27s age was perceived by an untrained audience, but the audience was unable to relate it to a specific age group

Rigging Realistic Skin Deformation with Muscle Systems

Realistic skin deformation is one of the major criteria for creating believable, dig- itally enhanced characters. Muscle simulation is one of the more popular techniques used in filmmaking. It helps bring a sense of realism to the character by adding subtle, secondary motion to the skin. Small features like these make the character appear more lifelike. This thesis focuses on the generation of a character rig and implementation of a digital muscle system for a tiger. The rig is built and animated in Maya and the Maya Muscle tool was used to create the muscle system. The muscle deformations are compared to the standard smooth skinning method in a walk and run animation
