InstancedMesh class

Many copies of one Geometry / Material pair, each placed by its own model transform.

Use an InstancedMesh for foliage, crowds, debris, or any scene that holds many copies of the same mesh. Attach it to a node with an InstancedMeshComponent; the whole set is then one render item, one pipeline, and one cull test rather than one node per copy.

Phase 3c carries a per-instance transform only. The naive backend still issues one draw call per instance.

Constructors

InstancedMesh({required Geometry geometry, required Material material})
Creates an instanced mesh that draws geometry shaded by material. It starts with no instances; add them with addInstance.

Properties

geometry → Geometry
The geometry drawn for every instance.
final
hashCode → int
The hash code for this object.
no setterinherited
instanceCount → int
The number of instances.
no setter
material → Material
The material every instance is shaded with.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

addInstance(Matrix4 transform) → int
Adds an instance placed by transform and returns its index.
clearInstances() → void
Removes every instance.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
removeInstanceAt(int index) → void
Removes the instance at index. Instances after it shift down by one, so their indices change.
setInstanceTransform(int index, Matrix4 transform) → void
Replaces the transform of the instance at index.
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
