3D Hand Info
The 3D Hand Info node captures and outputs detailed information about the position and rotation of a user’s hand in 3D space. Unlike 2D hand tracking, the 3D Hand Info node is more performance-intensive, making it essential for special effects artists to enable detection only when needed. This node provides precise 3D coordinates and rotation angles for individual finger keypoints, which can be useful for creating realistic interactions, gesture-based effects, and animations.
Input
| Name | Data Type | Description |
|---|---|---|
| Enable | Boolean | Activates this node when checked |
| Camera | Camera | The camera that provides the input viewport space |
| Hand | String | Either the left or right hand to detect |
Output
The 3D Hand Info node outputs data in array format, allowing you to access information about each finger joint individually through additional nodes.
| Name | Data Type | Description |
|---|---|---|
| Keypoint Position | Vec3 | The positions of the 3D hand's keypoints in an array format. Use the node “Get Item from Array” to access a specific keypoint position on a hand. |
| Keypoint Rotations | Vec3 | The rotations of the 3D hand's keypoints in an array format. Use the node “Get Item from Array” to access a specific keypoint rotation on a hand. |
