## Parameters

### Object

Parameter ID: `GV_SPLINE_INPUT_OBJECT`

All **spline** objects can be connected to this input port.

### Offset

Parameter ID: `GV_SPLINE_INPUT_POINT` · Range: [0..100%]

Use the offset value to define the desired location on a given spline. The first spline point reflects an offset value of 0%, the end of the spline an offset value of 100%. The value at the position output port is contingent upon the points that control the shape of the spline.

### Segment

Parameter ID: `GV_SPLINE_INPUT_SEGMENT` · Range: [0..2147483647]

Since splines can contain numerous segments (e.g., a text spline that consists of several letters), the number of desired segments can be defined using the segment input port. The segment count will begin at **0**, i.e., the first segment will have the number **0**, the second **1** and so on.

### Position

Parameter ID: `GV_SPLINE_OUTPUT_POSITION` · Range: [XYZ ]

Outputs the coordinates of a position along the spline (as defined by the Offset value and the Matrix Mode setting).

### Tangent

Parameter ID: `GV_SPLINE_OUTPUT_TANGENT` · Range: [XYZ ]

Tangents define the run of the curve before and after the position along the curve. This port outputs the tangent for the chosen position along the spline as a vector.

### Length

Parameter ID: `GV_SPLINE_OUTPUT_LENGTH` · Range: [-∞..+∞]

Outputs the length of the chosen spline segment, as a Real number.

### Closed

Parameter ID: `GV_SPLINE_OUTPUT_IS_CLOSED`

Outputs a Boole value of 0 if the spline in open or **1** if the spline is closed (splines can be closed by enabling the Close Spline option in the **Attribute Manager**).

### Segments

Parameter ID: `GV_SPLINE_OUTPUT_SEGMENTS` · Range: [-2147483648..2147483647]

Outputs the total number of spline segments. When passing the number of a segment to the **Segment** input port, keep in mind that the number of the first segment is **0**.
