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...

VMI Blog VIII: Voices in the Digital Twin

A night-time flight around Macquarie Island, reflecting both technical progress, technical issues, and a composite narrative of scientists who have worked there – an initial experiment in Digital Twin story-telling.Plus: demonstration of 3rd-person VR actor and satellite-derived inflow of vegetation mapping.

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...

How to generate SRT subtitles from audio recordings using Word

A quick note about a free-ish (or relatively low cost) and not-too-finicky but a-bit-technical way to generate subtitles for video interviews using Microsoft Word – up to 1hr in length (00:59:59,999) – or longer if you cut up your video into <1hr transcripts. How long this will work, I have...

VMI Blog IV

A brief 9-minute overview of work-in-progress on Virtual Macquarie Island for the VMI Project. 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...

VMI Blog III

A bit of progress on VMI visualization using the latest version of Cesium for Unreal. Mainly working on lookdev and accurate geolocation of assets. These are unmodified renders straight from Unreal, running in real time – so quite impressive. Still – there are glitches and issues to be sorted out,...

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.

No New Messages

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...

VMI Blog II

As mentioned in the previous blog post, I’m exploring the excellent WaterLine water system, which is enabling me to ~finally~ get some decent results with shorelines – something that is clearly a subject of active development in computer graphics, as the physics are so complicated and hard to simulate from...
