Sneak Peeks: Adobe 2020 R&D projects for 3D graphics
Friday, July 31, 2020 | Written by Jim Thacker
Adobe previewed some of the 3D graphics projects under development at Adobe Research, the company's research and development department, from a semi-automated 3D modeling system to a new physically based real-time renderer.
The company has not announced any release dates for any of the projects or even the applications to which it will belong, but gives an indication of where the company is going with its product development.
The sneak peeks were shown in yesterday's livestream on new features in Adobe's Substance Suite, along with Substance Designer 2020.2 and a new IBL creation system for Substance Alchemist.
The R&D preview itself starts at 00:49:00 in the video above.
Material creation: Convert a single source image into a PBR material
Of all the examinations exhibited, the best known was a new system for automatically generating PBR material from a single photo source image.
Similar functionality was added to Substance Alchemist earlier this year in the form of the new Image to Material filter added in Substance Alchemist 2020.2.
The underlying algorithm was trained with machine learning techniques on real source images and automatically generates accurate normal and displacement maps from individual source photos.
Modeling: Design 3D projects without having to edit the model directly
Other R&D projects exhibited included a new user-guided 3D shape modeling system: the video appears to be an independent application called Structure.
The video shows the software that generates procedural variants of 3D objects such as sofas and changes overriding parameters such as the overall width and the number of seat cushions.
The user can choose the version they like best and then use it as the basis for a new “generation” of variants to work step-by-step on a final design without ever having to edit the model directly.
Retopology: Convert the raw geometry into all-tri and all-quad networks
The video also showed a new "programmable remesher" that reduced the geometry of dense sources to even Tris: a slide showed a 10 million poly source that was decimated to 524,000 triangles.
The technology could be used to reduce the poly number of raw scan data to a level that can be used in production.
Adobe also said that a similar system for creating all-quad networks is under development that has potential applications for retopologizing character models for animation.
Rendering: new physically based real-time renderer and vector graphics rendering
The rendering technologies on display included a new physically based real-time renderer that generates a progressive preview of the above 3D environment.
The preview is grainy and not completely photorealistic, but the test scene is pretty crazy, as multiple angled mirrors create nested reflections layer by layer.
A separate demo showed rendering in vector graphics.
Of all the projects presented, it was the most specific for Adobe's current applications. A 3D model in Dimension was rendered as a vector outline to which a custom stroke style was applied in Illustrator.
Physics: The new method of incremental potential contact simulates squichy solids
But perhaps the most unexpected tech demo was one of a new physics system based on the article Incremental Potential Contact: Intersection- and Inversion-free, Large-Deformation Dynamics.
The new IPC method (Incremental Potential Contact) solves nonlinear elastodynamics in a computationally efficient way and closely mimics the behavior of real materials from fabric to rubber.
