Wound bed of a pressure ulcer. The injured blood vessel was prepared to show the expulsion of RBC, and then swell to cut off blood flow while a clot forms around it.

Quickly assembled in a few hours for addition to a storyboard. Emphasis of this scene is on the mucosal barrier protecting epithelial cells from commensal bacteria in the small intestine.

Inspired by a coral reef, the microvilli and bacteria were animated, and then distributed over the surface of a cellular mesh which was box-modelled to depict the crypts of the large intestine. The volumetric lighting was achieved by casting a sunlight over a cube with a water volumetric shader and bump map.

Found a really effective way to apply subsurface scattering based on the 'pointyness' of the mesh. This effect combined with a hand painted subdermal color map helped really helped make the patient look alive.

I sculpted and painted the textures here myself, with extensive research into how pressure ulcers appear typically on patients. This included displacement, alpha, specularity, normals, etc. Subsurface scattering was generated based on the ‘pointyness’ of the mesh.

First major project I took while working with blender. This underwent extensive revisions. Skin cells were distributed over the model on a path array, which allowed fast adjustments, and animation of many different pathological skin states.
