developer.nvidia.com/nvidia-omniverse
An open, Interactive 3D Design Collaboration Platform for Multi-Tool Workflows to simplify studio workflows for real-time graphics.
It supports Pixar’s Universal Scene Description technology for exchanging information about modeling, shading, animation, lighting, visual effects and rendering across multiple applications.
It also supports NVIDIA’s Material Definition Language, which allows artists to exchange information about surface materials across multiple tools.
With Omniverse, artists can see live updates made by other artists working in different applications. They can also see changes reflected in multiple tools at the same time.
For example an artist using Maya with a portal to Omniverse can collaborate with another artist using UE4 and both will see live updates of each others’ changes in their application.

Double Negative pulls plans of listing on Stock Exchange
DNEG said last month it was looking to raise £150m from a float on the LSE’s Main Market. This valued the firm at more than £600m.
But yesterday it said it has decided to postpone the listing due to ‘ongoing market uncertainty’.
The London-based group added that it had received ‘a strong level of interest from investors’ and still intends to go public once market conditions improve.

Magic Leap looking for 9th round of investments
Having burned through $2.6bn – that’s billion – on its way to producing an AR headset that has so many limitations it seemingly has zero chance of becoming a consumer device, the upstart has announced it is now part way through series E funding.
That’s just a Silicon Valley way of saying it’s on a fifth formal round of begging to banks and venture capitalists to help it keep going before the biz finally starts making money. In reality, it is the manufacturer’s eighth funding round, with the most recent being a cash influx of $280m in April this year. That money appears to be running out, or just simply not enough, just six months later.

MDL – NVidia Material Definition Language
www.nvidia.com/en-us/design-visualization/technologies/material-definition-language/
THE NVIDIA MATERIAL DEFINITION LANGUAGE (MDL) gives you the freedom to share physically based materials and lights between supporting applications.
For example, create an MDL material in an application like Allegorithmic Substance Designer, save it to your library, then use it in NVIDIA® Iray® or Chaos Group’s V-Ray, or any other supporting application.
Unlike a shading language that produces programs for a particular renderer, MDL materials define the behavior of light at a high level. Different renderers and tools interpret the light behavior and create the best possible image.

Photography basics: Lumens vs Candelas (candle) vs Lux vs FootCandle vs Watts vs Irradiance vs Illuminance
https://www.translatorscafe.com/unit-converter/en-US/illumination/1-11/
The power output of a light source is measured using the unit of watts W. This is a direct measure to calculate how much power the light is going to drain from your socket and it is not relatable to the light brightness itself.
The amount of energy emitted from it per second. That energy comes out in a form of photons which we can crudely represent with rays of light coming out of the source. The higher the power the more rays emitted from the source in a unit of time.
Not all energy emitted is visible to the human eye, so we often rely on photometric measurements, which takes in account the sensitivity of human eye to different wavelenghts
