Evaluate Path
Evaluate Path
Section titled “Evaluate Path” Category Shape
Is Pair Node: No
Evaluates a point on a vector path at a specified offset, returning the position, tangent, and transformation matrix for that point. This is useful for placing objects along paths or extracting information about the path geometry.
Inputs
Section titled “Inputs” Offset
Section titled “ Offset ” Type: Double
Default: 0.0
The "probing" value along the path. If Normalize Offset is true, 0 is the start of the path, and 1 is the end of the path. If Normalize Offset is false, it is a distance along the path.
Normalize Offset
Section titled “ Normalize Offset ” Type: Boolean
Default: true
If true, the Offset is normalized to the range [0, 1], where 0 is the start of the path and 1 is the end of the path. If false, the Offset is treated as a distance along the path.
Outputs
Section titled “Outputs” Position
Section titled “ Position ” Type: VecD
Default: (0, 0)
An absolute position on canvas of the evaluated point on the path.
Tangent
Section titled “ Tangent ” Type: VecD
Default: (0, 0)
The tangent vector at the evaluated point on the path, indicating the direction of the path at that point.
Matrix
Section titled “ Matrix ” Type: Matrix3x3
Default: Identity
A transformation matrix with position and tangent. You can use this matrix to place an object at the evaluated point on the path.
