SphereGeometry

SphereGeometry ⟵ BufferGeometry

A geometry class for a sphere with given radius and segment counts.

SphereGeometry creates a sphere geometry that is centered on the origin, with customizable radius and segment counts for smoothness. The sphere is created by sweeping vertices around the Y axis (horizontal) and Z axis (vertical).

Methods

SphereGeometry(f32 radius, u32 widthSegments, u32 heightSegments, f32 phiStart, f32 phiLength, f32 thetaStart, f32 thetaLength, const Color& color)

Universal constructor - covers all cases with smart defaults

radius	Sphere radius	1.0f
widthSegments	Number of horizontal segments (minimum 3)	32
heightSegments	Number of vertical segments (minimum 2)	16
phiStart	Horizontal starting angle	0.0f
phiLength	Horizontal sweep angle size	2π
thetaStart	Vertical starting angle	0.0f
thetaLength	Vertical sweep angle size	π
color	RGBA color for all vertices	0xFFFFFFFF (white)

SphereGeometry* clone(bool recursive) const

Creates a copy of this geometry

recursive

Whether to clone descendants as well

false

void copy(const SphereGeometry& geometry)

Copies properties from another geometry

geometry

Source geometry to copy from

void buildSphere()

Builds the sphere geometry with vertices, indices, and colors

void dispose()

Frees GPU-related resources
