FBX CoreAI is the technology foundation behind Fittingbox’s digital eyewear experiences. It combines an AI Engine, a Vision Engine and a 3D Engine to understand faces, track movement, reproduce eyewear frames accurately and render them in real time. It powers Fittingbox solutions including Virtual Try-On, Digital Frames and Optical Fit. 

Fittingbox uses the camera on a smartphone, tablet or computer to analyze facial landmarks, face shape, head movement and viewing angle. It then positions a realistic 3D model of the selected frame with the appropriate scale, perspective and alignment, continuously updating the rendering as the user moves. 

An accurate virtual try-on requires both precise facial analysis and accurate 3D frame data. Fittingbox reconstructs the face in 3D, detects key eye and facial reference points, and tracks movement in real time. The dimensions and proportions of each frame are preserved during digitization, helping the glasses remain stable and naturally aligned on the face.

Fittingbox uses eyewear-specific AI models and computer vision to understand frames, facial geometry and fitting points. Because the models are designed specifically for eyewear, they address the positioning, fitting and rendering requirements of glasses.

Fittingbox digitizes a frame’s geometry, proportions, materials, colors, lenses and finishes to create an accurate digital version. Its 3D Engine preserves precise dimensions and reproduces light, reflections and surface appearance. Automated production also helps maintain consistent visual quality across large eyewear catalogs.
