Mesh class base Geometry

Defines the shape and appearance of a 3D model in the scene.

It consists of a list of MeshPrimitive instances, where each primitive contains the Geometry and the Material to render a specific part of the 3d model.

Constructors

Mesh(Geometry geometry, Material material)

Creates a Mesh consisting of a single MeshPrimitive with the given Geometry and Material.

Mesh.primitives({required List<MeshPrimitive> primitives})

Creates a Mesh composed of the supplied MeshPrimitive list.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

localBounds → Aabb3?

Local-space union of every primitive's Geometry.localBounds, or null when no primitive has computable bounds.

no setter

morphTargets → MorphTargetData?

The morph target data of this mesh's first morphed primitive, or null when no primitive carries targets. Every primitive of an imported mesh shares one target count and order (the importers validate it), so the first primitive's names, defaults, and count speak for the whole mesh.

no setter

primitives → List<MeshPrimitive>

The list of MeshPrimitive objects that make up the Geometry and Material of the 3D model.

final

runtimeType → Type

A representation of the runtime type of the object.

Methods

clone() → Mesh

Returns a shallow copy: a new Mesh with new MeshPrimitives that reuse this mesh's Geometry and Material instances.

markLocalBoundsDirty() → void

Invalidate the cached localBounds. Rarely needed, since the cache already detects a replaced primitive geometry and a bumped Geometry.localBoundsVersion; call this only after mutating a geometry's bounds through a path that leaves its version unchanged.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
