Here we distill language specific to apparel manufacturing for clarity toward the shared goals of the 3DBP ecosystem. The whitepaper “3D Body Processing Ecosystem Overview” simplified the processes within the 3DBP ecosystem using four assets: cover, coveroid, human, and humanoid. From this we understand a cover to be any product, garment, or material worn on a human and a coveroid and humanoid to be the models of the finished forms. Here we build upon this foundation to consider where language fails to provide clarity crossing the physical to virtual realms within the 3DBP ecosystem. Through this discussion, apparel challenges are highlighted from both the perspective of the apparel practitioner (requiring subjective, heuristic, sensory processes) and the software architect (requiring objective, logical processes). Perspectives on fit are provided clarity for future dialogue toward cross-platform solutions suited to the 3DBP ecosystem. The terms are applicable beyond the influence of current trends or style aesthetics and therefore scal- able, relevant to well established manufacturing practices, yet sensitive to the art of garment design which is, and will remain, foundational to apparel practice. Keywords: garment fit, fit, 4D fit, fit assessment, fit mapping, 3DBP ecosystem, humanoid, coveroid 1. Introduction Discussion herein considers apparel fit language suited to both physical and digital space apparel prac- tice with the goal to engage conversation toward a larger treatise for a thorough dissemination of ap- parel fit language. Terminology will reference the four assets summarizing processes within the 3DBP ecosystem where the term humanoid is understood to be any representation of a human, cover is un- derstood to be any body-worn product, and coveroid is any representation of a cover. As the act of modelling humans and covers is established apparel practice, the terms humanoid and coveroid can be understood to be models (representations) of physical objects in either physical or digital space. The term cover includes all finished body worn products including molded products and wearables (body-worn products meant to monitor the bio-chemical activity of the wearer). Covers for consumers or wearers (humans) are developed on models (humanoids) as test samples (coveroids). [1] This paper will discuss apparel fit terminology to ensure definitions bridge the physical to digital realms concerning the following areas of discussion. 1. Humans and Humanoids Body Data 2. Covers and Coveroid Geometry 3. Cover and Coveroid Sizing 4. Human-to-Cover and Humanoid-to-Coveroid Interaction - Fit Assessment 2. Terminology 2.1. Human and Humanoid Body Data 3D Humanoids A humanoid is any representation of the human used for product development. 3D humanoids can be created from real or synthetic human body data (see below). There are numerous methods available for both booth scanners and photogrammetry scanning apps. * connect@fashionshouldempower.com Proceedings of 3DBODY.TECH 2022 13th Int.
