Transform Array
Method #
This node is used to create an Array of ‘points’ from various other internal Notch sources. Specifically:
| Point Source | Effect |
|---|---|
| Sets of Nulls | Multiple Null nodes can be attached to the Point Source input to create an array with one element per Null. |
| Particle Root Nodes | Attaching a Particle Root Node to the Point Source input will generate an Array element for each particle in the particle system. |
| Blob Tracker | Attaching a Blob Tracker to the Point Source input will cause an Array element to be created for each detected blob. |
When used with particle systems, enable determinism or make sure the Particle Root Num Particles matches the live particle count as closely as possible.
See the Array Sources node to see how this node is used in the nodegraph to multi-instance child nodes.
The Transform Array node can also be used for initialising arrays that can be addressed via JavaScript.
The number of elements in the array may vary per frame, up to the defined maximum. The source of the transforms is typically a GPU buffer, so there is some latency in accessing them.
The output transform array may be used directly with a Clone To Transform Array, or to clone other nodes within a Field System or Particle System.
Parameters
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
Parameter Details Position X Move along the local x-axis.
Position Y Move along the local y-axis.
Position Z Move along the local z-axis.
Rotation Heading Rotate around the local y-axis.
Rotation Pitch Rotate around the local x-axis.
Rotation Bank Rotate around the local z-axis.
Scale X Scale along the local x-axis.
Scale Y Scale along the local y-axis.
Scale Z Scale along the local z-axis.
Control the inheritance of the transforms from the parent.
Parameter Details Position Toggle inheritance of the Position from the parent.
Rotation Toggle inheritance of the Rotation from the parent.
Scale Toggle inheritance of the Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.
These properties control the core behaviours of the node.
Parameter Details Max Element Count The maximum number of elements allowed in the transform array.
Low Latency Mode Reduces the number of frames of latency by which elements are updated in the transform array.
Apply Node Transforms To Array Elements Only When Enabled, transform changes applied to this nodes transform properties will also be applied to the array elements, and carried onto any nodes this data is used.
