Skin and soft tissue modeling and its impact on apparel modeling

Rigid body avatars do not fully define the complex interaction between human and body-worn product (humanoid-to-coveroid).  Skin and soft tissue modeling to create more realistic 3D humanoid body models are needed. We considered if humanoid split lines relevant to pattern-engineering practice can be related to biodynamic and fold lines of the skin. Changes in skin and tissue are expected, depending on the dermis, the effects of movement, and the effects of coveroid pressure. The physiological functions of the skin may be assigned mechanical parameters for dynamic study utilizing biodynamic excisional skin tension (BEST) lines, main folding lines (MFL) with Langer’s lines. Critical to such study is the connecting of the skin to the rig (humanoid virtual skeleton). The use of stable (skeletal feature points related to both the virtual skeleton and apparel block patterns) and morphological (skin feature points identifying areas of morphological variation and dynamic study) landmarks for connecting the skin to rig was analyzed. We utilized these landmarks to drive lines as BEST, MFL and Langer’s lines for the mapping of skin deformations. Initial findings suggest the use of stable and morphological landmarks could have profoundly positive effects throughout the entire digital product creation (DPC) production pipeline and should be further explored & are important in developing standard topology practice

Working Group Progress for IEEE P3141 - Standard for 3D Body Processing, 2019-2020

The 3D Body Processing Industry Connections (3DBP IC) group, an adjunct to IEEE P3141 Working Group (WG) is developing recommendations for 3D body processing interoperability to enable the exchange of 3D human body anthropometric related information across an ecosystem encompassing consumers to creators. Representatives from diverse industries aim to establish operating principles to aid in the transformation of the retail experience. This paper also updates the status of the IEEE P3141 Working Group, Standard for 3D Body Processing (3DBP) Working Group. This paper summarizes the 3DBP activities conducted during the past year (Q4 2019 - 2020) and provides an overview of the topics to be addressed in 2021. During 2020, the working group published two white papers focused on the Comparative Analysis of Measurement Methods, Past, Present, and the Future of 3D Scanning, and 3D Foot Measurements Terminology

IEEE Standard for Transparency of Autonomous Systems

Measurable, testable levels of transparency, so that autonomous systems can be objectively assessed, and levels of compliance determined, are described in this standard
