Maya type pointMatrixMultDL
Direct parent DGNode
Inventory Members defined or overridden here; inherited members are grouped by parent in each section.

Signature : PointMatrixMult(node) → PointMatrixMult.

Parameter Accepted type Default
node Union[str, om.MObject, om.MObjectHandle, om.MFnDependencyNode] Required

Wraps an existing node or stages a wrapper for an absent name; does not create the node. Call create() separately. An incompatible object or type can raise TypeError. Shared identity can return an already registered compatible wrapper.

Python properties defined or overridden here. R: read-only; R/W: a setter exists, subject to the member notes. om.* types belong to maya.api.OpenMaya.

No new Python property; see inherited members and specs below.

Properties inherited from DGNode15
Property Return type Access Description
dep_fn om.MFnDependencyNode R Live function set; unattached object when the node is missing.
uuid str | None R Live UUID, or the last staged value if still available.
name str | None R/W Live name, otherwise staged name.
absolute_name str | None R Absolute namespace name from MFnDependencyNode.absoluteName(); None without a node.
stripped_name str | None R/W Name without its namespace, or None when unnamed.
namespace str | None R/W Normalized namespace such as a:b; None at the root.
plugs Plugs | None R Live node plug manager; None otherwise.
is_valid_dep_fn bool R Function-set compatibility with the current MObject.
is_default_node bool R Whether this is a Maya default node; False without a node.
is_from_referenced_file bool R Whether the node comes from a referenced file; False without a node.
is_locked bool R/W Node lock, separate from plug locks.
is_shared bool R Shared state reported by Maya; False without a node.
plugin_name str | None R Associated Maya plugin name, possibly an empty string; None without a node.
affect_animation bool R Result of MFnDependencyNode.affectsAnimation(); False without a node.
type str | None R/W Live native type or staged type.
Properties inherited from Node10
Property Return type Access Description
mobject om.MObject R/W Live Maya object, or a null object.
mobject_handle om.MObjectHandle R/W Handle associated with the node.
api_type int | None R Maya API type identifier.
api_type_str str R API type name, for example "kTime".
exists bool R The wrapper currently has a live node.
is_null bool R The returned Maya object is null.
is_alive bool R The object exists with a valid, live handle.
is_valid_handle bool R Validity of the stored handle.
is_dag_node bool R Compatibility with om.MFn.kDagNode.
hash_code int R Maya handle hash.

Defaults and flags below are spec declarations, not guaranteed live values. A descriptor can return a proxy: .value reads its value; .plug accesses the Plug. Proxy names describe results, not private classes to import. Observed types come from a test fixture; disconnected geometry inputs may notably return None.

For writes where failure must be checked, use the Plug explicitly and verify live state. Descriptor setters do not propagate every native failure.

snapshot DGSnapshot Captures and stores an identity and spec-driven SVD dictionary.

svd SVDView Returns a read-only live view of source, value and destinations; it is not a frozen capture.

NODE_TYPE · Maya 2025.3 pointMatrixMult

NODE_REGISTRY and other class attributes not overridden here remain inherited. Exported Snapshot types describe dictionaries; use node.snapshot() to capture state.

Point Behavior
Identity A node recreated under the same name is a new Maya object.
Creation and geometry The constructor creates nothing; call create() before live operations.
Capture Snapshots can contain Maya objects; do not assume JSON-ready data or complete geometry reconstruction.
Usage The wrapper selects pointMatrixMult in Maya 2025.3 and pointMatrixMultDL in Maya 2026.3. Vector mode ignores translation, unlike point mode.

Self-contained Maya Python Script Editor example. In mayapy, initialize maya.standalone before this block. The demonstration creates its own nodes and removes them in finally.

from uuid import uuid4
import maya.api.OpenMaya as om
from weSkel.src.core.node.dg.point_matrix_mult.lib import PointMatrixMult
node = PointMatrixMult("api_point_matrix_mult_" + uuid4().hex[:8])
try:
node.create()
matrix = om.MTransformationMatrix()
matrix.setTranslation(om.MVector(1.0, 2.0, 3.0), om.MSpace.kTransform)
node.in_matrix = matrix.asMatrix()
node.in_point = (2.0, 0.0, 0.0)
node.vector_multiply = False
assert om.MVector(node.output.value).isEquivalent(om.MVector(3.0, 2.0, 3.0), 1e-6)
print("PointMatrixMult: native evaluation OK")
finally:
node.delete(snapshot=False)

Expected result : PointMatrixMult: native evaluation OK.

SDK checkpoint 87c3486. Member inventory checked against loaded classes in Maya 2025.3 and 2026.3; reads and compatibility are specified in the member cards. Example run in both versions, including explicitly documented expected failures. The example does not cover every method. Listed limitations remain in source; these checks do not validate the compiled package.
