CircleGeometry

CircleGeometry ⟵ BufferGeometry

A geometry class for a circle with given radius and segments.

CircleGeometry creates a circle geometry that is centered on the origin, lying in the XZ plane (Y = 0). The circle is constructed from triangular segments and can be used to create regular polygons or partial circles.

Methods

CircleGeometry(f32 radius, u32 segments, f32 thetaStart, f32 thetaLength, Color color)

Universal constructor - covers all cases with smart defaults

radius	Radius of the circle	1.0f
segments	Number of triangular segments (minimum 3)	32
thetaStart	Start angle for first segment in radians	0.0f
thetaLength	Central angle of circular sector in radians	2π
color	RGBA color for all vertices	0xFFFFFFFF

CircleGeometry* clone(bool recursive) const

Creates a copy of this geometry

recursive

Whether to clone descendants as well

false

void copy(const CircleGeometry& geometry)

Copies properties from another geometry

geometry

Source geometry to copy from

void buildCircle()

Builds the circle geometry with vertices, indices, and colors

void dispose()

Frees GPU-related resources

Properties

radius	f32	Radius of the circle
segments	u32	Number of triangular segments
thetaStart	f32	Start angle in radians
thetaLength	f32	Central angle in radians
color	Color	RGBA color for all vertices
