NeRF Visualization for Cultural Heritage

The release of NVIDIA’s Instant NeRF is a fantastic opportunity to explore the technology’s applications for cultural heritage visualization. There is, of course, a lot of hype about it and it’s utility for ‘ushering in the metaverse’ – I would take this with several large grains of salt, as the...

VMI Blog IX: Weather & Penguins!

A quick demo on work-in-progress on VMI, demonstrating progress on weather simulations and few other features. I’m using the fantastic UDS rather than the inbuilt UE volumetrics and particle systems, as this provides an off-the-shelf weather solution with a ton of customizable features via blueprints. This is working in conjunction...

GPlates Visualizations

GPlates is ‘a plate tectonics program..(used to)..manipulate reconstructions of geological and paleogeographic features through geological time.’ I’ve looked at (and used) GPlates on and off over the years – it’s definitely the kind of software you need to spend some time getting your head around, as it is deep and...

We’re making good progress on environmental visualization and placing animals in our VMI simulation. Gina Moore and I have been working closely together and have moved a huge amount of our workflow into Houdini and Houdini Engine, as this offers so many advantages over using inbuilt UE tools – especially...

VMI Blog VI: Metahumans Lighting Preview

One of the challenges of creating ‘beliveable’ Metahumans for VMI has been striking a fine balance between creating CG surrogates for our scientists – that they are more-or-less happy with – and avoiding stereotypes and cliches. It is not immediately apparent that the Metahuman interface sets out to avoid this,...

VMI Blog V: A Metahuman Experiment

Part of the brief we developed for our Virtual Macquarie Island project involves the deployment of in-world avatars of the scientists we interviewed. We’ve been very fortunate to interview nine specialists with many decades of on-island experience between them, covering a wide range of disciplines. What is striking about the...

The movie covers the development of the environment and terrain model, ocean workflow and initial development tests in endemic fauna visualization – the Southern Elephant Seal and Wandering Albatross. Lots more in the pipeline! November 2021...

360 Blog – Experiments

Some experiments in mono & stereoscopic 360 renders for VR. The youtube video is a test of panoramic rendering from Unreal Engine 4.26 using Cesium for Unreal. There are technical problems with panoramic rendering, LOD and tile loading that I am investigating – but its a good start.

An old iPhone recording (2016) of a scam telephone call, using a synthesized voice, recorded on an old answering machine (2000) that uses an even older synthetic voice, meets NVIDIA’s Audio2Face (2021) – ‘an AI-powered application that generates expressive facial animation from just an audio source.’ A conjunction both sinister...
