“…A simple armature in the pelvic region [ 38 , 39 , 40 , 41 , 68 , 69 ] was used in the preliminary study, which produced too-short legs and thus incorrect knee position. If the femur bone was moved, the buttocks were unnaturally curved, with a lack of volume, as shown in Figure 6 .…”

Study Regarding the Kinematic 3D Human-Body Model Intended for Simulation of Personalized Clothes for a Sitting Posture

This study deals with the development of a kinematic 3D human-body model with an improved armature in the pelvic region, intended for a sitting posture (SIT), using Blender software. It is based on the scanned female body in a standing posture (STA) and SIT. Real and virtual measures of females’ lower-body circumferences for both postures were examined. Virtual prototyping of trousers was performed to investigate their fit and comfort on the scanned and kinematic 3D body models and to make comparison with real trousers. With the switch from STA to SIT, real and virtual lower-body circumferences increase and are reflected in the fit and comfort of virtual and real trousers. In SIT, the increased circumferences are attributed to the redistribution of body muscles and adipose tissue around the joints, as well as changes in joints’ shapes in body flexion regions, which are not uniformly represented on the kinematic sitting 3D body model, despite improved armature in the pelvic region. The study shows that average increases in waist, hip, thigh, and knee circumferences should be included in the process of basic clothing-pattern designs for SIT as minimal ease allowances, as should, in the future, armature designs that consider muscle and adipose tissues, to achieve realistic volumes for kinematic 3D body models in SIT.

“…Researchers have rigged the body scan avatars to enable movement and analyze fit in different active positions such as walking [30] and rock climbing [31]. Mixamo, an online auto-rigging service has been frequently used to generate animations from structures such as bones and joints based on marker positioning [32].…”

Digital garment simulations can be very useful for technical design teams when evaluating the fit of the functional or protective garments, especially when 3D body scanning technology is unable to fully capture certain poses. In this study, we tested a method of creating animated coverall simulations and using the obj files of three poses, i.e., A-pose, reaching front, and stepping front, for objective and subjective fit analyses. We used 29 body scans that were rigged in Mixamo to analyze ease amounts of digitally stitched coveralls in each pose. Pattern outlines were visible in the digital coveralls Circumferences, cross sections, volumes, as well as crotch heights, were measured from the obj files of the clothed and minimally clothed digital bodies. Results showed that our method was effective in creating realistic wrinkles/folds that indicate tightness. There were significant differences in the overall ease across the three poses. A-pose yielded the highest overall ease followed by reaching front and stepping front. Crotch ease was significantly the lowest in the stepping front pose. Animations were found to be signaling additional fit clues.

“…Such system is able to track several points of the body during the motion, but does not contain information for the whole body part. This information have to be recreated using rigging of the body [8] and morphing of the human body mesh based on specialized algorithms. A powerful method is the use of trained data based 3D models for the human body and a large set of pictures, as reported in [9].…”

Modern hardware makes high speed 3D scanning (4D scanning) of moving clothed humans possible and opens new possibilities for optimization of the pattern in order to provide improved clothing comfort. At the same time the high speed scanning process generates a large amount of data which analysis over times series is not more as efficient as it is for single 3D frames. This contribution reports first steps in the area of evaluation of high speed scanned data sets of humans with not tight clothing. The newest export of the IBV scanner MOVE4D in the form of triangulated meshes of the complete scan (human and textiles) is critically analyzed. It was recognized that it provides an efficient initial mesh for additional analysis from one side and some effects like small folds and areas, where the cloth is sticking to the body cannot be recognized anymore. After that the method of the approximate distances between different raw data cloud points are analyzed for a raising arms motion of a clothed human. The optical analysis demonstrates good correlation with the reality and suitability of the method for fast analysis of the clothing behavior based on 4D scanned frames.
