DTRACK4 features

DTRACK4 is ART's current tracking software for Windows — without a dedicated ART Controller. It combines proven DTRACK workflows with a modern 3D monitor, flexible configurations, and direct integration into your applications.

Relevant passages in the DTRACK4 manuals are linked directly below (PDF opens in a new tab).

System requirements

• Windows 10 or 11 on your tracking PC (Installation Guide, p. 26)
• 2× Gigabit Ethernet — two 1 Gbit ports (User's Guide, p. 30)
• Jumbo frames up to 9 KB on the network adapter (User's Guide, p. 30)

Cameras & tracking hardware

Supported

• AT7-50, ARTTRACK6/M, and AT7-80 tracking cameras (Installation Guide, p. 24)
• ARTTRACK5(/C) systems when at least one supported camera (ARTTRACK6/M, AT7-50, or AT7-80) is part of the setup
• No software limit on the number of cameras in one system (User's Guide, p. 71)
• No software limit on the number of Targets in one system
• Synchronization between cameras for a common capture time (User's Guide, p. 81)

Not supported

• ARTTRACK1/2/3, TRACKPACK(/E), Firewire cameras, and legacy ART Controllers (SyncCard3)
• Standalone SMARTTRACK/3/M — still supported in the DTRACK3 software line
• Inertial sensors (YEI, Trivisio, and similar)

Details on licensing and migration from older systems are on the licensing page.

Calibration & tracking volume

Room & coordinate systems

Calibration defines the shared coordinate system within the Tracking volume.

• Room calibration with angle tools of different sizes
• Multiple coordinate systems per configuration
• Room adjustment in the 3D monitor — refine the coordinate system after calibration
• Transfer a room calibration to another configuration

Camera setup

• Up to three sync groups — cameras in different groups do not interfere with each other
• Exclusion zones per camera — for example to mask sun reflections
• Camera modes for a higher maximum frame rate with a reduced vertical field of view
• Automatic exposure control across all cameras (exposure time and flash length optimized together)
• Manual exposure settings per camera when needed

Bodies, markers & targets

• Body administration with the integrated ART target library — standard ART targets do not need separate calibration (Target Library, p. 100)
• Adjust the body coordinate system in the administration tool or in the 3D monitor (Programmer's Guide, p. 10)
• 3D marker calculation can be enabled or disabled as required
• Retroreflection: How passive spherical markers send IR light back to the camera — blog article

Interaction devices

• Flystick2+ with integrated radio link (Programmer's Guide, p. 17)
• Finger tracking 2 including tactile variant (radio link) (Tactile control, p. 134)
• Measurement Tool with COOTRANS — align the ART coordinate system to an external reference and measure points with export (reference points, p. 95)
• Active targets such as AMC6 via modulated flash synchronization (Installation Guide, p. 60)

Configurations & day-to-day operation

• Multiple configurations on one system — for example different applications, target sets, or coordinate systems
• Password protection for saved configurations
• Display brightness on cameras adjustable — status LEDs, rings, and 7-segment displays, down to full deactivation for dark environments

Data output & integration

• 6DOF tracking data via ART's UDP data stream
• Multicast and multiple output channels for parallel consumers (Programmer's Guide, p. 21)
• Direct use in Autodesk VRED, Unity, and Unreal Engine, or custom applications via the C++ and Java SDK (interfaces overview, p. 155)

See the interfaces section for plugins, SDK downloads, and connectivity documentation.

Documentation & quick guides

• DTRACK4 multi-camera quick guide
• Installation guide
• User's guide
• Programmer's guide
• All manuals and quick guides in the resources section

Deployment options

• Separate backend and frontend — the tracking backend can run headless as a Windows service on a dedicated PC while operators use the GUI on another machine (Backend Service PC, p. 155)
