- bool cubic_interp
true, the position between two cached points is interpolated cubically, and linearly otherwise.
The points along the Curve3D of the Path are precomputed before use, for faster calculations. The point at the requested offset is then calculated interpolating between two adjacent cached points. This may present a problem if the curve makes sharp turns, as the cached points may not follow the curve closely enough.
There are two answers to this problem: Either increase the number of cached points and increase memory consumption, or make a cubic interpolation between two points at the cost of (slightly) slower calculations.
- float h_offset
The node’s offset along the curve.
- bool loop
true, any offset outside the path’s length will wrap around, instead of stopping at the ends. Use it for cyclic paths.
- float offset
The distance from the first vertex, measured in 3D units along the path. This sets this node’s position to a point within the path.
- float unit_offset
The distance from the first vertex, considering 0.0 as the first vertex and 1.0 as the last. This is just another way of expressing the offset within the path, as the offset supplied is multiplied internally by the path’s length.
- float v_offset
The node’s offset perpendicular to the curve.
