circleGeometry

Creates a THREE.CircleGeometry

CircleGeometry is a simple shape of Euclidean geometry.

It is constructed from a number of triangular segments that are oriented around a central point and extend as far out as a given radius. It is built counter-clockwise from a start angle and a given central angle. It can also be used to create regular polygons, where the number of segments determines the number of sides.

Attributes

name

string: Name for this geometry.

Default: ''

vertices

array of THREE.Vector3: See THREE.Geometry#vertices.

Default: []

colors

array of THREE.Color: See THREE.Geometry#colors.

Default: []

faceVertexUvs

array of (array of (array of THREE.Vector2)): See THREE.Geometry#faceVertexUvs.

Default: []

faces

array of THREE.Face3: See THREE.Geometry#faces.

Default: []

dynamic

bool: See THREE.Geometry#dynamic.

Set to true if attribute buffers will need to change in runtime (using "dirty" flags).

Unless set to true internal typed arrays corresponding to buffers will be deleted once sent to GPU.

Default: false

radius

number: Radius of the circle

segments

number: Number of segments (triangles), minimum = 3

thetaStart

number: Start angle for first segment, default = 0 (three o'clock position).

thetaLength

number: The central angle, often called theta, of the circular sector.

The default is 2*Pi, which makes for a complete circle.

resourceId

string: The resource id of this object, only used if it is placed into resources.

Default: ''

Notes:

This component can be added into <resources/>! See Resource Types for more information.
