R3DS Wrap4D – generate topology from animated textures
https://www.russian3dscanner.com/wrap4d/
R3DS Wrap4D is an extended version of Wrap designed specifically for 4D processing. It takes a sequence of textured 3D scans as an input and produces a sequence of meshes with a consistent topology as an output.
The solution includes 12 new nodes. At the heart of the pipeline is the FacialWrapping node which combines the power of the BlendWrapping node with the results from the lip and eyelid detector. The idea behind the node is to provide a robust result that doesn’t require cleanup.
How ‘Dune’ VFX supervisor Paul Lambert invented the Nuke’s Image Based Keyer
So, what is the IBK keyer? The very non-technical answer to that is that the ‘image- based keyer’ is a proprietary keyer in Nuke that typically deals with classic bluescreen or greenscreen plates (that need keying) by recognizing that these plates do not always have uniform color coverage. We’ve all seen uneven blue and greenscreens; that’s one place where the IBK Keyer can come in handy.
VQGAN + CLIP AI made Music Video for the song Canvas by Resonate
” In this video, I utilized artificial intelligence to generate an animated music video for the song Canvas by Resonate. This tool allows anyone to generate beautiful images using only text as the input. My question was, what if I used song lyrics as input to the AI, can I make perfect music synchronized videos automatically with the push of a button? Let me know how you think the AI did in this visual interpretation of the song.
After getting caught up in the excitement around DALL·E2 (latest and greatest AI system, it’s INSANE), I searched for any way I could use similar image generation for music synchronization. Since DALL·E2 is not available to the public yet, my search led me to VQGAN + CLIP (Vector Quantized Generative Adversarial Network and Contrastive Language–Image Pre-training), before settling more specifically on Disco Diffusion V5.2 Turbo. If you don’t know what any of these words or acronyms mean, don’t worry, I was just as confused when I first started learning about this technology. I believe we’re reaching a turning point where entire industries are about to shift in reaction to this new process (which is essentially magic!).

Rez – python friendly cross-platform package manager
https://github.com/nerdvegas/rez
Rez is a cross-platform package manager with a difference. Using Rez you can create standalone environments configured for a given set of packages. However, unlike many other package managers, packages are not installed into these standalone environments. Instead, all package versions are installed into a central repository, and standalone environments reference these existing packages. This means that configured environments are lightweight, and very fast to create, often taking just a few seconds to configure despite containing hundreds of packages.
Shutter Speed and Rolling Shutter
https://www.studiobinder.com/blog/what-is-rolling-stutter
Rendering rolling shutter in Arnold
Rolling_shutter is used to simulate the type of rolling shutter effect seen in footage shot with digital cameras that use CMOS-based sensors such as Blackmagics, Alexas, REDs, and even iPhones. This method is implemented by rolling (moving) the shutter across the camera area instead of the entire image area all at the same time.

Björn Ottosson – OKHSV and OKHSL – Two new color spaces for color picking
https://bottosson.github.io/misc/colorpicker
https://bottosson.github.io/posts/colorpicker/
In the Munsell color system, colors are described with three parameters, designed to match the perceived appearance of colors: Hue, Chroma and Value. The parameters are designed to be independent and each have a uniform scale. This results in a color solid with an irregular shape. The parameters are designed to be independent and each have a uniform scale. This results in a color solid with an irregular shape. Modern color spaces and models, such as CIELAB, Cam16 and Björn Ottosson own Oklab, are very similar in their construction.
By far the most used color spaces today for color picking are HSL and HSV, two representations introduced in the classic 1978 paper “Color Spaces for Computer Graphics”. HSL and HSV designed to roughly correlate with perceptual color properties while being very simple and cheap to compute.
Today HSL and HSV are most commonly used together with the sRGB color space.
One of the main advantages of HSL and HSV over the different Lab color spaces is that they map the sRGB gamut to a cylinder. This makes them easy to use since all parameters can be changed independently, without the risk of creating colors outside of the target gamut.
The main drawback on the other hand is that their properties don’t match human perception particularly well.
Reconciling these conflicting goals perfectly isn’t possible, but given that HSV and HSL don’t use anything derived from experiments relating to human perception, creating something that makes a better tradeoff does not seem unreasonable.
With this new lightness estimate, we are ready to look into the construction of Okhsv and Okhsl.
