CylinderGeometry

CylinderGeometry ⟵ BufferGeometry

A geometry class for a cylinder with given top/bottom radius and height.
CylinderGeometry creates a cylinder geometry that is centered on the origin, with the cylinder axis aligned along the Y axis. The cylinder can have different radii at the top and bottom, allowing for cone-like shapes.

Methods

CylinderGeometry(f32 radiusTop, f32 radiusBottom, f32 height, u32 radialSegments, u32 heightSegments, bool openEnded, f32 thetaStart, f32 thetaLength, const Color& color)

Universal constructor - covers all cases with smart defaults

radiusTop	Radius of the cylinder at the top	1.0f
radiusBottom	Radius of the cylinder at the bottom	1.0f
height	Height of the cylinder	1.0f
radialSegments	Number of segments around circumference	32
heightSegments	Number of segments along height	1
openEnded	Whether ends are open (true) or capped (false)	false
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

CylinderGeometry* clone(bool recursive = false) const

Creates a copy of this geometry

recursive

Whether to clone descendants as well

void copy(const CylinderGeometry& geometry)

Copies properties from another geometry

geometry

Source geometry to copy from

void buildCylinder()

Builds the cylinder geometry with vertices, indices, and colors
