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.)

Oceans of the Earth

Paul has written up some of the work we have been doing since February – with some useful resources and images:

3d Rapid Prototype of the Global Ocean

In concert with Paul Bourke (WASP, UWA) we have produced an accurate 3d model of the global ocean – based upon the dataset derived from GEBCO and the WSG 84 world geodetic system.

Here’s a couple of snapshots:

It is remarkable to hold this in your hands (even if it’s a bit flakey and fragile) – as a way of inspecting the structure of the ocean it is most impressive and detailed. Naturally there are issues with this first rough draft – such as a missing Mediterranean – but that’s solvable in future iterations. The next question is what to cast it in – I can foresee steel or, more interestingly, transparent bluish acrylic.

As a sculptural artifact, this would seem quite marketable.
