AFrame-Curves

Components for dealing with spline curves

curve component

This defines a Catmull-Rom spline curve. It is exposed on el.components.curve.curve,

Property	Type	Description	Default
tension	number	The Catmull-Rom Tension	0.25
closed	boolean	Whether it joins back up with it's tail	false

curve-point component

A point that tracks itself in 3D world space and updates the curve that it has changed.

No configuration required

draw-curve component

Property	Type	Description	Default
curve	selector	Curve to draw, defaults to the curve on the same entity.
spacing	number	How far apart to place the line segments, smaller is a smoother curve.	0.5
tangent	boolean	Draw curve tangents	false
normal	boolean	Draw curve normals	false
length	number	Length to draw the normal and tangent markers	0.1

clone-along-curve component

Apply this to the curve element, or set one seperately, to instance element at fixed intervals along a curve. They will be rotated to follw the curve.

Property	Type	Description	Default
curve	selector	Optional, pick a particular curve to use, it defaults to the curve on it's own element
spacing	number	How far apart to place the elements	1
scale	vec3	Scale of the elements	{"x":1,"y":1,"z":1}

<a-curve>

Describes a curve doesn't display anything unless one of the other components is used

Default Components:

Default component	Settings
curve	{}

Entity Attribute Mappings:

Property	Mapping
closed	"curve.closed"
tension	"curve.tension"

<a-curve-point>

This is used to set the control points of the curve, they don't need to be immediate children.

Default Components:

Default component	Settings
curve-point	{}

<a-draw-curve>

Describes a curve this uses the draw-curve component to draw a line where the curve is.

Default Components:

Default component	Settings
draw-curve	{}
curve	{}

Entity Attribute Mappings:

Property	Mapping
curve	"draw-curve.curve"
closed	"curve.closed"
tension	"curve.tension"
