Get Locations At Distances On Curve

Given a set of curve points and a normalized distance between 0-1.0, return the location on a closed curve. 0 is the first point on the curve, 1.0 is also the first point because the is an implicit segment connecting the first and last points. Values outside the range 0-1.0 will be wrapped to that range, for example -0.4 is equivalent to 0.6 and 1.3 is equivalent to 0.3. This is a simplistic curve-following node, intended for curves in a plane, for prototyping purposes.

Installation

To use this node enable omni.graph.nodes in the Extension Manager.

Inputs

Name	Type	Descripton	Default
Curve (inputs:curve)	pointd[3][]	The vertex values of the curve to be examined.	[]
Distance (inputs:distance)	double	The distance along the curve, normalized to the range 0-1.0.	0.0
Forward (inputs:forwardAxis)	token	The direction vector from which the returned rotation is relative. The legal values are ‘X’, ‘Y’, or ‘Z’.	X
Up (inputs:upAxis)	token	The world Up vector, the curve should be in a plane perpendicular with this. The legal values are ‘X’, ‘Y’, or ‘Z’.	Y

Outputs

Name	Type	Descripton	Default
Location on curve at the given distance in world space. (outputs:location)	pointd[3]	Location	None
World space orientation of the curve at the given distance. It may not be smooth for some curves. (outputs:orientation)	quatf[4]	Orientation	None
World space rotation of the curve at the given distance. It may not be smooth for some curves. (outputs:rotateXYZ)	vectord[3]	Rotations	None
