Radomír Měch

Principal Scientist, Adobe Research

San Jose

Radomír heads the 3D Graphics and Interactive Design Lab at Adobe Research. He leads teams of research scientists and research engineers, and one invaluable technical artist. The researchers span areas of 2D and 3D design, 2D and 3D graphics, with focus on AI driven technologies. His areas of research are procedural modeling, with a particular focus on interaction with procedural models and casual modeling, rendering, 3D printing, and image evaluation algorithms. Currently, he is focusing on 3D driven image editing, 3D driven diffusion methods and developing frameworks to accelerate testing of new AI-driven interactive workflows.

Radomír believes that Adobe Research has an efficient and enjoyable model for producing magic features for our products. Many of Adobe Research’s projects start with internships. A typical researcher is involved in 2-6 internships each summer investigating new ideas. Many of those internships lead to university collaboration and results in high quality publications. The close ties with academia allow the researches to keep up to speed with latest academic results but also attract top talent in terms of interns and full time hires. Each researcher has also projects that are in further stages, where the investigation is followed by building a prototype that can be shown to product teams, or the prototype is already successfully sold and the researcher, with possible help from the tech transfer engineer, transfers the technology into a product.

Radomír’s role is to interface with Adobe’s product teams, the customers of the technologies developed by his team and to define and drive the strategy and research themes for the lab.  Since the inception of his group in 2008 his team has shipped many technologies, including:

Radomír’s projects:

Procedural modeling, casual modeling and 3D printing

Before Radomír became a manager in 2008, and while his team was growing, he had time to built a procedural modeling framework. The goal of the project was to allow users to create new procedural brushes or other tools in our applications.

The system first shipped in Flash Authoring and then in Photoshop CS6, enhanced in CC 14.1. With Daichi, the procedural artist on board, he and his team shipped more advanced Deco filters in 14.3 (including image frame, flame and tree filter). Radomír continues to enchance the framework, for example by adding support for iOS, since it provides means for Daichi to deploy new features and for others to quickly prototype new tools. For example, the procedural watercolor simulation shipped in Eazel was prototyped in Deco. See below for more details on the system.

Radomír is a big proponent of 3D casual modeling. In general, he would like to make it easier for people to create and modify 3D content. With the increase popularity of 3D printing and Virtual Reality there will be an increasing need for 3D content. Conversely, being able to easily create 3D content will aid the adoption of 3D printers and virtual reality. Procedural modeling is one of the possible means towards easy modeling and Radomír have explored several projects on making it easy to author and control procedural or parametric models.

He has also been a proponent of 3D printing. He has been part of the initial push for 3D printing at Adobe and has worked on several projects, several resulting in publications (link to Bedrich), some only in patents (http://www.3ders.org/articles/20150413-adobe-steps-further-into-3d-printing-industry-with-print-smoothing-patent.html), and some made it to product (multitone 3D printing as experimental feature in Photoshop CC 2014).

As an avid photographer, he was also interested in developing some features for Lightroom. With help from two researcher’s from the Media Intelligence Lab,Radomír has developed in house technology over past few years for automatic image cropping, to enhance the image composition or for zoom in, for image saliency, for evaluation of image aesthetics and for album curation – selecting representative images from image sets.

These are exciting projects for Radomír as a researcher since he is learning new skills and as a customer who needs such features.

Other projects that shipped and to which he has contributed directly are the procedural splat based water color simulation on iPad (Eazel), the ray-tracer in Photoshop, 3D extrusions in Photoshop, Multitone  3D printing in Photoshop (for smoothly mixing two colors in FDM printers), or pattern scripts in Photoshop.

Many other internship or collaboration project resulted in a publication. The list of publications below can give you an idea of the variety of topics.
