DI4D

DI4D is a facial performance capture technology brand developed by Dimensional Imaging Limited, a Scottish imaging business established in Glasgow in 2003. Its work spans digital humans, character animation and digital doubles for games, film and television, with earlier applications in medical and facial research. Following the original operating company's liquidation in 2025, Clear Angle Studios acquired DI4D's technology, intellectual property and brand assets in February 2026.

The business developed markerless capture methods that record facial movement as detailed, changing surface geometry. These methods support the translation of an actor's expressions into animated characters, combining facial scanning, performance tracking and rigging. Its entertainment work includes facial performances and digital doubles for productions such as Blade Runner 2049, Free Guy, The Last of Us Part II and Alan Wake 2.

Capture and animation technology

DI4D's technology suite connects controlled facial scanning with performance capture and animation production:

• DI4D PRO uses a seated multi-camera array to capture dense facial surface geometry over time.
• DI4D HMC uses stereo head-mounted cameras to record facial performances alongside body motion capture and audio.
• PURE4D combines high-resolution expression data with head-mounted camera footage through a machine learning-assisted pipeline designed to support large volumes of game animation.
• Neural Rigging, introduced in 2025, transfers facial geometry animation onto actor-specific rigs so animators can edit the results non-destructively.

These capabilities address different stages of character production, from recording an actor's facial shapes to preparing performances for animation. Alongside entertainment applications, the company's earlier stereophotogrammetry systems supported orthodontic and medical research.

Technology integration

Under Clear Angle Studios, DI4D's markerless tracking technology has been integrated into TopoTrack, a tracking and geometry stabilization service for FACS scans, 4D sequences and head-mounted camera performance data. The integration connects facial capture with character asset preparation, with ongoing services delivered through Clear Angle Studios' capture infrastructure.
