Class ScyllaBarrelShape

Parametric barrel: a lathed profile rotated around the Y axis. The profile narrows at top and bottom (chamfered cap edges), carries two belt hoops (one near the top, one near the bottom - the classic wooden-barrel iron-band look), and terminates in flat top and bottom cap discs. Centered on the origin.

Syntax

[AddComponentMenu("Scylla/Geometry/Barrel")]
public sealed class ScyllaBarrelShape : ScyllaShapeBase3D

Remarks

The profile is parameterized by Radius (the body radius in the cylindrical regions), Height (total Y extent), ChamferInset (how much narrower the cap rings are than the body), ChamferHeight (the vertical run of each chamfer), BeltOutset (how far each belt protrudes radially beyond the body), BeltHeight (each belt's vertical span; both belts share this), BeltDistanceFromCap (vertical distance from each cap to the corresponding belt's center), and Segments (circumferential subdivisions, clamped to [3, 256]).

Each profile strip is emitted with its own analytically derived flat normal (flat in the strip's profile direction, smooth around the circumference). Strip boundaries get duplicated vertices so the joins between body / chamfer / belt are crisp creases.

For per-face coloring, ColoringMode selects between LidsBeltAndBody (default, 3 resolver indices: body = chamfers + body cylinders, belt = middle hoop, lids = top + bottom caps) and PerSection (9 resolver indices, one per profile section - the original busier preset).

Properties

BeltDistanceFromCap

Vertical distance from each cap to the center of the corresponding belt. The lower belt center is at -Height/2 + BeltDistanceFromCap; the upper belt center at +Height/2 - BeltDistanceFromCap. Clamped at build time so both belts remain inside the available body region. Setting this triggers an immediate mesh rebuild.

Declaration

public float BeltDistanceFromCap { get; set; }

Property Value

Type	Description
float

BeltHeight

Vertical span of each belt's outer cylindrical wall. Both belts share this value. The complete belt sub-profile (lower flange + outer wall + upper flange) spans this total height. Setting this triggers an immediate mesh rebuild.

Declaration

public float BeltHeight { get; set; }

Property Value

Type	Description
float

BeltOutset

Radial protrusion of each belt beyond the body radius (beltRadius = Radius + BeltOutset). Setting this triggers an immediate mesh rebuild.

Declaration

public float BeltOutset { get; set; }

Property Value

Type	Description
float

ChamferHeight

Vertical run of each chamfer strip. The profile transitions from the cap radius to the body radius across this Y span at each end. Setting this triggers an immediate mesh rebuild.

Declaration

public float ChamferHeight { get; set; }

Property Value

Type	Description
float

ChamferInset

Radial cut-in of the chamfer: how much narrower the top and bottom cap ring radius is compared to the body radius (capRadius = Radius - ChamferInset). Clamped to [0, Radius - epsilon] at build time. Setting this triggers an immediate mesh rebuild.

Declaration

public float ChamferInset { get; set; }

Property Value

Type	Description
float

ColoringMode

Selects the per-face color granularity used when an IFaceColorResolver is active. Geometry is identical in all modes; only how many distinct resolver indices the barrel emits changes. See BarrelColoringMode for the exact index layout. Setting this triggers an immediate mesh rebuild.

Declaration

public BarrelColoringMode ColoringMode { get; set; }

Property Value

Type	Description
BarrelColoringMode

Height

Total height of the barrel along the Y axis. The mesh is centered on the origin so it extends from -Height/2 to +Height/2. Setting this triggers an immediate mesh rebuild.

Declaration

public float Height { get; set; }

Property Value

Type	Description
float

Radius

Body radius in the cylindrical sections of the profile (between the chamfers and the belt flanges). The cap ring radius is derived as Radius - ChamferInset; the belt radius as Radius + BeltOutset. Setting this triggers an immediate mesh rebuild.

Declaration

public float Radius { get; set; }

Property Value

Type	Description
float

Segments

Circumferential subdivisions around the Y axis. Higher values produce a rounder silhouette. Clamped to [3, 256] when set and at build time. Setting this triggers an immediate mesh rebuild.

Declaration

public int Segments { get; set; }

Property Value

Type	Description
int

Methods

Build(Mesh, float, float, float, float, float, float, int, float, BarrelColoringMode, IFaceColorResolver)

Populates target with a parametric barrel mesh. Existing mesh data is overwritten.

Declaration

public static void Build(Mesh target, float radius, float height, float chamferInset, float chamferHeight, float beltOutset, float beltHeight, int segments, float beltDistanceFromCap = 0.18, BarrelColoringMode coloringMode = BarrelColoringMode.LidsBeltAndBody, IFaceColorResolver resolver = null)

Parameters

Type	Name	Description
Mesh	target	Destination mesh. Must be non-null.
float	radius	Body radius (cylindrical regions).
float	height	Total height along Y.
float	chamferInset	Radial cut-in of the cap chamfers (cap radius = radius - inset).
float	chamferHeight	Vertical run of each chamfer.
float	beltOutset	Radial protrusion of the belt beyond the body.
float	beltHeight	Vertical span of the belt's outer wall.
int	segments	Circumferential subdivisions. Clamped to `[3, 256]`.
float	beltDistanceFromCap	Vertical distance from each cap to the corresponding belt's center. The lower belt sits this far above the bottom cap; the upper belt sits this far below the top cap. Clamped to fit between the chamfers and the central body region.
BarrelColoringMode	coloringMode	Selects how the resolver indices are assigned. LidsBeltAndBody (the default) uses three indices total - `0` for the body (chamfers + body cylinders), `1` for the belts (both belts share this color), `2` for the lids (top + bottom caps). PerSection uses nine indices, one per profile section in build order (bottom cap, lower chamfer, lower body, lower belt, middle body, upper belt, upper body, upper chamfer, top cap).
IFaceColorResolver	resolver	Optional per-face color resolver. When non-null, a per-vertex color channel is emitted with one solid color per logical face. When null, no color channel is written.

BuildMesh(Mesh)

Subclass extension point: write vertex / triangle / normal / uv data into target from the shape's serialized parameters. The base class calls Clear(bool) before invoking this method and UnityEngine.Mesh.RecalculateBounds() afterwards, so subclasses should not invoke either themselves.

Declaration

protected override void BuildMesh(Mesh target)

Parameters

Type	Name	Description
Mesh	target	The owned mesh to populate. Already cleared by the base class.

Overrides

ScyllaShapeBase3D.BuildMesh(Mesh)

GetMeshName()

Returns the shape's mesh name as it should appear on the generated mesh asset. Defaults to the subclass type name; override to provide a friendlier label.
