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
geometryshaded bymaterial. It starts with no instances; add them with addInstance.
Properties

final
- hashCode → int

Methods
-
addInstance(
Matrix4 transform) → int -
Adds an instance placed by
transformand 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.
