Workflow: From Scan to Custom Avatar Creation
How to Take a 3D Body Scan
For the best results during a 3D body scan, it's important to wear snug-fitting clothing and maintain a straight posture. Scanning systems often include real-time pose validation, offering immediate feedback to help users adjust their stance for accurate data collection. Advanced clothing detection features ensure garments don’t interfere with capturing precise body measurements.
Professional scanning setups go beyond basic body dimensions. They create a detailed digital model that includes body shape, skin texture, and even facial expressions. Some 4D scanning systems take this further by capturing expressions at up to 30 frames per second, enabling the creation of avatars with realistic movements and facial animations. Once the scan is complete, the raw data enters a processing pipeline for refinement.
Processing Scan Data Into Avatars
The raw data from a scan undergoes several steps to transform it into a custom avatar. The process starts with cleaning up the data and removing noise. Then, retopology is applied to shape the data into a polished character model. Rigging adds a digital skeleton, enabling natural movement, while skinning connects the character’s mesh to this structure for fluid motion. To enhance the visual appeal, materials and shaders are applied, often using tools like Character Creator and iClone.
The Instituto de Biomecánica (IBV) describes their method:
"IBV provides the technology to fit the same surface template and skeleton to raw 3D scan data, generating a high resolution watertight 3D body model that perfectly fits customer's body."
AI-powered systems have made significant strides in precision. For example, 3DLOOK’s technology achieves 89% accuracy in BMI predictions based on estimated weight. Most users - 76% - see deviations of just 5% or less, and the average prediction error is a mere 3.5%. Body measurements show an accuracy rate of 96–97% and over 95% consistency in repeated scans.

Veronica Cimolin from the Department of Electronics, Information and Bioengineering at Politecnico di Milano highlights the importance of such accuracy:
"The accuracy of body measurements is a crucial element for the successful application of avatars..."
Studies comparing scanning technologies back up these claims. For instance, the "Gate" 3D body scanner outperformed a gold-standard optoelectronic system in measuring a 20 cm cube with greater accuracy. Additionally, 3D body scanning has proven more precise than traditional weight scales for assessing body composition, including lean muscle mass and fat levels.
Impact of Realism on Clothing Fit and Movement
The precision offered by advanced 3D scanning directly impacts the realism of digital avatars, leading to better-fitting clothing and more natural simulations of garment movement. This level of detail helps minimize sizing errors and reduces high return rates. When avatars accurately mirror a person’s body shape and proportions, they provide a clear prediction of how clothes will fit and behave in motion.
However, creating highly realistic avatars is a balancing act. While smooth and visually appealing avatars are popular, they might oversimplify the human form, potentially complicating the design of well-fitted clothing patterns. Interestingly, research has shown that consumers are more likely to make purchases - by as much as 200% - when they see garments on avatars resembling their own body type. In one study, participants rated photo-realistic avatars significantly higher in realism (M = 4.94) compared to mannequin-like avatars (M = 3.06, p < .001), with strong statistical support (F (1, 61) = 13.33; p < .05; partial η² = .18).
These advancements in realism extend well beyond the fashion industry.
Applications Beyond Fashion
The precision and realism made possible by 3D scanning open doors to a variety of applications outside of clothing. For instance, the same technology that improves garment sizing also supports personalized nutrition plans, fitness tracking, and health monitoring. In healthcare and fitness, detailed body measurements provide professionals with reliable data to track changes in body composition over time.
Realistic avatars also play a significant role in gaming and virtual reality. High levels of both visual and behavioral realism enhance user immersion and overall experience, although inconsistencies between these elements can disrupt the experience. Moreover, research shows that cognitive and emotional trust significantly influence users’ willingness to adopt avatar-based technologies, with trust accounting for 79% of this adoption intention (R² = .79).
As 3D scanning technology evolves, the scope of applications for realistic avatars continues to expand, paving the way for innovative solutions in healthcare, gaming, and beyond.
