Some Test Renders of an Unusual Perspective on the Ocean

Here are a variety of renders from various stages of the production process. They derive from a variety of datasets relating to the Antarctic ocean – primarily GEBCO. The ocean is rendered as a polygonal surface mesh, using shaders to impart a sense of volume. The tricky bit is getting the lighting and transparency right – in order to impart a sense of ‘wateriness” without sacrificing too much detail. Naturally this has an interplay with the transparency/translucency of the object and the refractive index of the material shader (generally set to 1.3). Some of the renders are preview tests for fulldome, so they are rendered in a fisheye projection, assuming a unidirectional seating arrangement with azimuth at the centre of the image.

Needless to sat, rendering this large dataset at 3200×3200 consumes from 5-20 minutes per frame. Fortunately I have secured access to a renderfam (more details TBA.)
