New OmniGraph nodes in Create 2022.3

Overview

The release of Create 2022.3 brings with it a lot of new and exciting OmniGraph nodes that you can use for animation, physics, curves, UI and lots more! Check out the full list of new nodes below!

Animation

• AnimCurve

  Evaluates curve animation

• AnimationGraphUpdate

  Update Animation Graph

• UnpackAnimationGraphPoseBundle

  Unpack Animation Graph Pose Bundle as skeleton hierarchy

FlowUSD

• FlowBlocks

  Flow block count

• FlowSimTime

  Node exposing simulation time to OG

Curve

• PushoutCurvePoints

  Sample points along curves in the input curvesBundle. When a range of these points falls within the bounding sphere / box of the prims within the collisionBundle, this node attempts to push those subsections of points outside the bounding volume in some reasonable way. This node outputs two bundles: a pointsBundle that contains one prim per polyline containing the displaced points of that polyline, and a curvesBundle that contains curve prims fit to those displaced points.

Event

• OnLoaded

  Triggers the output on the first update of the graph after it is created or loaded. This will run before any other event node, and will only run once after this node is created.

Flow Control

• SwitchToken

  Outputs an execution pulse along a branch which matches the input token. For example if inputs:value is set to ‘A’ it will continue downstream from outputs:outputNN if there is an inputs:branchNN that is set to ‘A’

Math

• Ceil

  Computes the ceil of the given decimal number a, which is the smallest integral value greater than a

• ToUint64

  Converts the given input to a 64 bit unsigned integer of the same shape. Negative integers are converted by adding them to 2**64, decimal numbers are truncated.

Function

• EndsWith

  Determines if a string ends with a given string value

• StartsWith

  Determines if a string starts with a given string value

• SlangNode

  Compute node compiling and executing slang code

Bundle

• ExtractBundle

  Exposes readable attributes for a bundle as outputs on this node. When this node computes it will read the latest attribute values from the target bundle into these node attributes

Scene Graph

• GraphTarget

  Access the target prim the graph is being executed on. If the graph is executing itself, this will output the prim path of the graph. Otherwise the graph is being executed via instancing, then this will output the prim path of the target instance.

• ReadOmniGraphValue

  Imports a data value from the Fabric cache that is located at the given path and attribute name. This is for data that is not already present in OmniGraph as that data can be accessed through a direct connection to the underlying OmniGraph node.

UI

• Button

  Create a button widget on the Viewport

• ComboBox

  Create a combo box widget on the Viewport

• OnWidgetClicked

  Event node which fires when a UI widget with the specified identifier is clicked. This node should be used in combination with UI creation nodes such as OgnButton.

• OnWidgetValueChanged

  Event node which fires when a UI widget with the specified identifier has its value changed. This node should be used in combination with UI creation nodes such as OgnSlider.

• Placer

  Contruct a Placer widget. The Placer takes a single child and places it at a given position within it.

• ReadWidgetProperty

  Read the value of a widget’s property (height, tooltip, etc).

• ReadWindowSize

  Outputs the size of a UI window.

• Slider

  Create a slider widget on the Viewport

• Spacer

  A widget that leaves empty space.

• VStack

  Contruct a Stack on the Viewport. All child widgets of Stack will be placed in a row, column or layer based on the direction input.

• WriteWidgetProperty

  Set the value of a widget’s property (height, tooltip, etc).

• WriteWidgetStyle

  Sets a widget’s style properties. This node should be used in combination with UI creation nodes such as Button.

Omni PhysX Scene Queries

• SceneQueryOverlapBoxAll

  Returns a list of prim paths of all colliders that overlap the input box.

• SceneQueryOverlapBoxAny

  Checks whether any colliders overlap the query input box.

• SceneQueryOverlapPrimAll

  Returns a list of prim paths of all colliders that overlap the input Prim.

• SceneQueryOverlapPrimAny

  Checks whether any colliders overlap the query input Prim.

• SceneQueryOverlapSphereAll

  Returns a list of prim paths of all colliders that overlap the input sphere.

• SceneQueryOverlapSphereAny

  Checks whether any colliders overlap the query input sphere.

• SceneQueryRaycastAll

  Returns a list of prim paths of all colliders that are hit by the input ray.

• SceneQueryRaycastAny

  Returns whether any colliders are hit by the input ray.

• SceneQueryRaycastClosest

  Finds the closest collider that is hit by the input ray.

• SceneQuerySweepSphereAll

  Returns a list of prim paths of all colliders that are hit by the input ray.

• SceneQuerySweepSphereAny

  Returns whether any colliders are hit by the input ray.

• SceneQuerySweepSphereClosest

  Finds the closest collider that is hit by the input ray.

Omni PhysX Vehicles

• VehicleGetDriveState

  Retrieving drive related simulation state of an omni.physx vehicle. Note: the simulation must be running if this node is evaluated, else the resulting behavior will be undefined.

• VehicleGetWheelState

  Retrieving wheel related simulation state of an omni.physx vehicle. Note: the simulation must be running if this node is evaluated, else the resulting behavior will be undefined.

Synthetic Data Generation

  Synthetic Data node to expose the scene instances semantic hierarchy information

• SdInstanceMappingPtr

  Synthetic Data node to expose the scene instances semantic hierarchy information

• SdLinearArrayToTexture

  Synthetic Data node to copy the input buffer array into a texture for visualization

• SdOnNewFrame

  Synthetic Data postprocess node to execute pipeline after the NewFrame event has been received

• SdOnNewRenderProductFrame

  Synthetic Data postprocess node to execute pipeline after the NewFrame event has been received on the given renderProduct

• SdPostInstanceMapping

  Synthetic Data node to compute and store scene instances semantic hierarchy information

• SdRenderProductCamera
