Photorealistic Dynamic Simulation Materials for System Dynamics

MaterialPass (Material Passport) MTP mtlp

Advanced materials not only for Design but also for Simulation

MaterialPass materials as digital catalogs not only hold Physically Based Rendering (PBR) textures/colors (Metal - Roughness) but also hold extra Data/Information like mass, weight, water consumption, etc, and anything we see today (or will see tomorrow) as Psets and Qtos in Industry Foundation Classes (IFC) and other schemas for “simulation” purposes

Structure

1. Material - Materials that are GIS/BIM/PLM/VFX-ready and globally registered once and can be used multiple times
2. Object - Objects that are GIS/BIM/PLM/VFX-ready and globally registered once and can be used multiple times
3. Product - Products that are GIS/BIM/PLM/VFX-ready and globally registered once and can be used multiple times
4. Facility - Facilities that are Smart Cities-ready and globally registered once and can be used multiple times

In this way, we can decouple geometry and semantics

• Geometry - As we know there are many geometric modeling paradigms, which some are good for geometric visual representation, some for analysis and simulation, etc, so always different geometric modeling paradigms is a significant obstacle in integrating different worlds, for instance, GIS and BIM, or BIM and PLM, or VFX and BIM, so on
• Semantics - Data/Information/Knowledge Units

This way can solve known challenges because they modeled once globally through the best paradigm for that specific use-case and are ready-to-use in different worlds that can be assembled together (geometry and data/information/knowledge units) like LEGOs

Usage

1. Speed up System Dynamics, Multi-Agent Systems and Circular Economy
2. Integrating GIS, BIM, PLM, CAD, CAE, CAM, VFX, XR, and other different worlds together
3. Better focus on Geometry, Optics, Physics, and Perception which will advance some areas like Computer Graphics and Artificial Intelligence (AI), projects like Kaolin and PyTorch3D

Proposal

materialpass's Issues

Adding data into the asset

Test scenario: Adding IFC meta tags into an asset

1. Download a test asset like a chair with complex geometries and materials, shaders and textures
2. Open it on Blender and add IFC classes and related data/information
3. We will have a BIM-ready asset, save it as HelloWorld.mtlp files and HelloWorld.prdp file
4. Test it in different platforms

• Its geometry modeling paradigm?
• Its accuracy? Does it so close to its reality? in size, etc
• Its materials and finishes are correct and supported?

5. OK
