Spline Adds 3D Hand tracking Directly Inside Its V2 Editor.

Spline is bringing webcam-powered 3D Hand tracking directly into Spline V2, giving designers a way to control browser-based 3D scenes with physical movements and gestures. The feature turns a standard camera into an input source, without requiring creators to leave the editor or set up dedicated motion-capture hardware.

The company announced the capability on LinkedIn, saying that 3D Hand tracking is now possible inside Spline V2. It builds on the editor’s support for interactive, real-time 3D content, but replaces conventional mouse, touch, or keyboard input with movements captured through a webcam.

That could make gesture-driven experiences considerably easier to prototype. A product team could create a virtual object that responds when someone moves a hand, while an educator could build a spatial demonstration controlled through gestures. Designers working on games, installations, digital showrooms, or experimental landing pages gain another input method without first moving the scene into a separate game engine.

Spline’s implementation uses the webcam as a video source, then captures hand movement for use within a scene. Based on the announcement, tracking happens in real time inside the V2 workflow, allowing hand position and gestures to influence interactive content while it is being designed or tested.

The practical shift is less about video itself and more about input. Conventional webcam support displays an image stream. Hand tracking interprets what is happening within that stream, giving the scene structured movement information that can be used for interaction and control.

Spline has not yet published detailed documentation covering the available gestures, tracking points, event controls, supported browsers, or whether processing happens locally. Those details will determine how suitable the feature is for production projects. Teams should also test camera permission flows, performance on lower-powered hardware, lighting conditions, and behavior when a hand moves outside the camera frame.

The update lands as Spline expands V2 beyond a conventional modeling canvas. As previously covered, the company has rebuilt its browser editor around newer creation and automation workflows. It has also introduced an AI Agent Mode for generating interactive 3D simulations. Hand tracking adds a physical interaction layer to that broader direction.

The most immediate use case is rapid prototyping. Instead of writing a custom camera pipeline before validating an idea, a creator can begin testing hand-controlled behavior in the same environment used to construct the scene.

Potential applications include:

• Product demonstrations, where a model reacts to hand position or a gesture.
• Interactive storytelling, with movement used to reveal content or alter a scene.
• Learning experiences, such as manipulating spatial diagrams without a controller.
• Games and playful web projects, where the webcam becomes an accessible input device.
• Installation prototypes, allowing agencies to test touch-free interactions before committing to specialist hardware.

For small teams, the main advantage is reduced setup. Browser-based hand tracking will not replace high-end motion capture where precision is critical, but it can shorten the path from concept to a working demonstration. It also makes gesture interaction available to creators who may be comfortable building visually but do not want to assemble a computer-vision stack from scratch.

Spline has not disclosed whether 3D Hand tracking is limited to particular paid plans, nor has it provided separate pricing for the capability. The announcement identifies it as a Spline V2 feature, so users will need access to that editor and a compatible webcam to try it.

What is Spline 3D Hand tracking?

Spline 3D Hand tracking is a V2 editor feature that uses a webcam as a video source to capture hand movements and gestures. Those movements can provide real-time interaction and control inside a 3D scene.

Who is 3D Hand tracking intended for?

It is relevant to designers and developers building gesture-controlled web experiences, prototypes, product demonstrations, games, educational content, or touch-free installations. It may be particularly useful for small teams that want to test an interaction without creating a separate hand-tracking pipeline.

Which Spline plan includes 3D Hand tracking?

Spline has not specified plan requirements or separate pricing in the announcement. The company has only confirmed that the capability is available directly inside Spline V2.
