Props

animation

TypeDescription
PropTypes.shape({ name: PropTypes.string, delay: PropTypes.number, loop: PropTypes.bool, onStart: PropTypes.func, onFinish: PropTypes.func, run: PropTypes.bool, })A collection of parameters that determine if this component should animate. For more information on animated components please see our Animation Guide.

arShadowReceiver

TypeDescription
PropTypes.boolWhen set to true, this control will act as a transparent surface and capture any shadows that are cast onto it.

dragPlane

TypeDescription
PropTypes.shape({ planePoint:PropTypes.arrayOf(PropTypes.number), planeNormal:PropTypes.arrayOf(PropTypes.number), maxDistance:PropTypes.number})When a drag type of "FixedToPlane" is given, dragging is limited to a user defined plane. The dragging behavior is then configured by this property (specified by a point on the plane and its normal vector). You can also limit the maximum distance the dragged object is allowed to travel away from the camera/controller (useful for situations where the user can drag an object towards infinity).

dragType

TypeDescription
PropTypes.oneOf(["FixedDistance", "FixedToWorld"])Determines the behavior of drag if onDrag is specified.|Value|Description||:------|:----------:||FixedDistance| Dragging is limited to a fixed radius around the user, dragged from the point at which the user has grabbed the geometry containing this draggable node||FixedDistanceOrigin| Dragging is limited to a fixed radius around the user, dragged from the point of this node's position in world space.||FixedToWorld| Dragging is based on intersection with real world objects. Available only in AR ||FixedToPlane| Dragging is limited to a fixed plane around the user. The configuration of this plane is defined by the dragPlane property.|The default value is "FixedDistance".

height

TypeDescription

uvCoordinates

TypeDescription
PropTypes.arrayOf(PropTypes.number)An array of 4 values [u0, v0, u1, v1] representing the UV-coordinates which determines how a texture should be tiled across the surface.Texture coordinates are represented on 2D U and V axes (essentially the X and Y axes of the image). The left edge of a texture is U = 0.0 and the right edge of the texture is U = 1.0. Similarly, the top edge of a texture is V=0.0 and the bottom edge of the texture is V=1.0.Specifying greater than 1.0 on either the U or V axis will cause the tile to repeat itself or clamp, depending on the Material's wrapS and wrapT properties. Specifying less than 1.0 on the U or V axis will render that texture partially over the entire surface.

For example, setting a Node's rendering order to -1 will cause the Node to be rendered before all Nodes with rendering orders greater than or equal to 0.
