TorusGeometry

TorusGeometry ⟵ BufferGeometry

A geometry class for a torus (donut) with given radius, tube and segment counts.
TorusGeometry creates a torus geometry that is centered on the origin, with the torus ring lying in the XZ plane and the tube cross-section extending along the Y axis. This provides a classic donut shape.

Methods

TorusGeometry(f32 radius, f32 tube, u32 radialSegments, u32 tubularSegments, f32 arc, const Color& color)

Universal constructor - covers all cases with smart defaults

radius	Major radius (center to tube center)	1.0f
tube	Tube radius (must be smaller than radius)	0.4f
radialSegments	Segments around the tube cross-section	12
tubularSegments	Segments around the torus ring	48
arc	Central sweep angle in radians	2π
color	RGBA color for all vertices	0xFFFFFFFF

TorusGeometry* clone(bool recursive = false) const

Creates a copy of this geometry

recursive

Whether to clone descendants as well

void copy(const TorusGeometry& geometry)

Copies properties from another geometry

geometry

Source geometry to copy from

void buildTorus()

Builds the torus geometry with vertices, indices, and colors

Properties

arc	f32	Central sweep angle in radians
color	Color	RGBA color for all vertices
radialSegments	u32	Number of segments around tube
radius	f32	Major radius of the torus
tube	f32	Radius of the tube
tubularSegments	u32	Number of segments around ring
