The Digital Dolphin

The digital dolphin is an android app that consists of a series of 3D anatomically accurate 3D models that demonstrate the basic thoracic anatomy of a harbour porpoise.

Understanding the threats marine wildlife are facing enables the successful campaign for changes to mitigate common threats. The underlying cause of strandings are not always immediately clear and so post mortem examinations are needed and samples collected to maintain the national cetacean tissue archive. These examinations and sample collections are facilitated by a system of volunteers on stranding programmes who must be adequately trained in cetacean anatomy in order to effectively determine the cause of death. The Digital Dolphin app aims to be an effective aid for volunteers learning basic anatomy of cetaceans as there are currently very few 3d resources available.

The models were built using a number of techniques and animated to communicate a number of interesting structures and processes of the heart and lungs.

App in use

The Digital Dolphin app allowed users to interact with the models. A very clean UI was used to make the experience as natural and intuitive as possible.

Alveoli animation

Alveoli of cetaceans have myoelastic sphincters that periodically cut off the oxygen. The exact purpose of this is not entirely known. This animation demonstrates this anatomical mechanism.

Lungs breathing

The lungs were animated using blend deformers to simulate the movement of lungs breathing in and out.

Skeleton and Skin Models

The skeleton and skin models were segmented from CT data and sculpted and painted in mudbox to create realistic textures.
