This system will result in asymmetric steer angles such that the line defined by the non-steered wheel axle and the lateral lines of the steered wheels meet at the same point. As a consequence, when following the path around a curve, the inner wheel will turn more than the outer one. This avoids that some wheels need to slip sideways to stay on the path.

usdrt::PhysxSchemaPhysxVehicleBrakesAPI: Describes a braking system for a vehicle by specifying which wheels are connected to the brake control and by defining the brake torque that gets applied to those wheels. Currently, up to two braking systems are supported. Use the instance name TfToken "brakes0" and "brakes1" of this multipleApply schema to distinguish between the two braking systems. Note that system "brakes0" will be coupled to the brake control brake0 while system "brakes1" will be coupled to the brake control brake1 (see PhysxVehicleControllerAPI for the brake controls). An example for using two systems is to provide brake and handbrake control (the former applying brake torque to all wheels and the latter applying brake torque to the rear wheels only). This API schema has to be applied to a prim with PhysxVehicleAPI applied. Can only be used for vehicles that have a drive (see PhysxVehicleDriveBasicAPI or PhysxVehicleDriveStandardAPI).
usdrt::PhysxSchemaPhysxVehicleClutchAPI: Properties of the PhysX vehicle clutch. If the clutch setup does not need to be shared among vehicle instances, it can be applied to the prim which has PhysxVehicleDriveStandardAPI applied. If the intent is to share the clutch setup, PhysxVehicleClutchAPI can be applied to a separate prim which can be linked to (see PhysxVehicleDriveStandardAPI).
usdrt::PhysxSchemaPhysxVehicleContextAPI: PhysX vehicles general settings. Has to be applied to a PhysicsScene prim. For any described attribute Fallback Value or Allowed Values below that are text/tokens, the actual token is published and defined in PhysxSchemaTokens. So to set an attribute to the value "rightHanded", use PhysxSchemaTokens->rightHanded as the value.

usdrt::PhysxSchemaPhysxVehicleDriveBasicAPI: Very simple drive model for a PhysX vehicle. A torque will be directly applied to the wheels that are marked as driven (see PhysxVehicleMultiWheelDifferentialAPI or deprecated attribute "driven" in PhysxVehicleWheelAttachmentAPI).
usdrt::PhysxSchemaPhysxVehicleDriveStandardAPI: Standard drive model for a PhysX vehicle. The available drive torque will be split equally between all the wheels that are marked as driven (see PhysxVehicleMultiWheelDifferentialAPI or deprecated attribute "driven" in PhysxVehicleWheelAttachmentAPI) unless the torque distributon is configured explicitly (see PhysxVehicleMultiWheelDifferentialAPI for details).
usdrt::PhysxSchemaPhysxVehicleEngineAPI: Properties of a PhysX vehicle engine. If the engine setup does not need to be shared among vehicle instances, it can be applied to the prim which has PhysxVehicleDriveStandardAPI applied.

usdrt::PhysxSchemaPhysxVehicleGearsAPI: Properties of PhysX vehicle gears. If the gears setup does not need to be shared among vehicle instances, it can be applied to the prim which has PhysxVehicleDriveStandardAPI applied.

usdrt::PhysxSchemaPhysxVehicleMultiWheelDifferentialAPI: Describes which wheels of a vehicle are driven as well as the distribution of the drive torque among those wheels. Has to be applied to a prim with PhysxVehicleAPI applied. Can only be used for vehicles that have a drive (see PhysxVehicleDriveBasicAPI or PhysxVehicleDriveStandardAPI).
usdrt::PhysxSchemaPhysxVehicleSteeringAPI: Describes a steering system for a vehicle by specifying which wheels are connected to the steer control and by defining the maximum steer angle for those wheels (see PhysxVehicleControllerAPI for the steer control).

usdrt::PhysxSchemaPhysxVehicleSuspensionAPI: Properties of a PhysX vehicle wheel suspension. If the suspension setup does not need to be shared among vehicle instances, it can be applied to the prim which has PhysxVehicleWheelAttachmentAPI applied. If the intent is to share the suspension setup, PhysxVehicleSuspensionAPI can be applied to a separate prim which can be linked to (see PhysxVehicleWheelAttachmentAPI).
usdrt::PhysxSchemaPhysxVehicleSuspensionComplianceAPI: Compliance describes how toe and camber angle and force application points are affected by suspension compression. Each compliance term is in the form of a graph with up to 3 points. The points in the graph consist of a normalized jounce value (with 0 meaning fully elongated and 1 fully compressed suspension) and a corresponding compliance value (which can be an angle or point etc. depending on the specific compliance term). The sequence of points must respresent monotonically increasing values of normalized jounce. The actual compliance value will be computed by linear interpolation based on the current normalized jounce. If any graph has zero points in it, a value of 0.0 is used for the compliance value. If any graph has 1 point in it, the compliance value of that point is used directly. This API schema has to be applied to a prim with PhysxVehicleWheelAttachmentAPI applied. If defined, then this setup takes precedence over the deprecated attributes suspensionForceAppPointOffset and tireForceAppPointOffset of the PhysxVehicleWheelAttachmentAPI API schema, the deprecated attributes camberAtRest, camberAtMaxCompression, camberAtMaxDroop of the PhysxVehicleSuspensionAPI API schema as well as the deprecated attribute toeAngle of the PhysxVehicleWheelAPI API schema.
usdrt::PhysxSchemaPhysxVehicleTankControllerAPI: PhysX vehicle tank controller to divert torque from the engine to the wheels of the tracks of a wheel based tank vehicle (see PhysxVehicleTankDifferentialAPI). Note that the "accelerator" attribute of PhysxVehicleControllerAPI still drives the engine torque whereas the thrust controls introduced here define how that torque gets diverted to the wheels, so both controls need to be used to drive a wheel based tank vehicle usually. This API schema has to be applied to a prim with PhysxVehicleAPI applied. Can only be used for vehicles that have a standard drive and a tank differential defined (see PhysxVehicleDriveStandardAPI, PhysxVehicleTankDifferentialAPI).
usdrt::PhysxSchemaPhysxVehicleTankDifferentialAPI: Differential to set up a wheeled tank vehicle. Describes which wheels of a vehicle are part of the tank tracks. The wheels in each tank track have a constraint applied to them to enforce the rule that they all have the same longitudinal speed at the contact point between the wheel and the tank track. Driven wheels that are not part of a tank track receive the torque split specified in physxVehicleMultiWheelDifferential:torqueRatios. Has to be applied to a prim with PhysxVehicleAPI applied. Can only be used for vehicles that have a standard drive (see PhysxVehicleDriveStandardAPI).
usdrt::PhysxSchemaPhysxVehicleTireAPI: Properties of a PhysX vehicle tire. If the tire setup does not need to be shared among vehicle instances, it can be applied to the prim which has PhysxVehicleWheelAttachmentAPI applied.

usdrt::PhysxSchemaPhysxVehicleWheelAPI: Properties of a PhysX vehicle wheel. If the wheel setup does not need to be shared among vehicle instances, it can be applied to the prim which has PhysxVehicleWheelAttachmentAPI applied. If the intent is to share the wheel setup, PhysxVehicleWheelAPI can be applied to a separate prim which can be linked to (see PhysxVehicleWheelAttachmentAPI).
usdrt::PhysxSchemaPhysxVehicleWheelAttachmentAPI: For every wheel of a vehicle, this class defines the attachment properties. Has to be applied to a prim that is a descendant of a prim with PhysxVehicleAPI applied. If the wheel attachment prim (the prim with PhysxVehicleWheelAttachmentAPI applied) is a UsdGeomXformable , then the position and orientation of the prim will be set by the vehicle simulation. If the wheel attachment prim has PhysicsCollisionAPI applied, then none of its descendants are allowed to have PhysicsCollisionAPI applied. If the wheel attachment prim is a UsdGeomXformable but does not have PhysicsCollisionAPI applied, then exactly one direct child prim among all descendants is allowed to have PhysicsCollisionAPI applied. That prim will be interpreted as the collision geometry of the wheel and its position and orientation will be set by the vehicle simulation too. Note that the relative transform between the collision geometry prim and the wheel attachment prim at the start of the simulation will be maintained (the relative transform with respect to the center of mass frame of the vehicle rigid body that is). If there is no desire to have the vehicle simulation control the transform of the wheel attachment prim, then a prim type that is not a UsdGeomXformable should be chosen.
usdrt::PhysxSchemaPhysxVehicleWheelControllerAPI: PhysX wheel controller that samples user input and allows direct control of the wheel torques and steer angle to drive the vehicle. Has to be applied to a prim with PhysxVehicleWheelAttachmentAPI applied and be a descendant of a prim with a PhysxVehicleAPI applied.

usdrt::RtChangeTracker: The RtChangeTracker class provides an interface for tracking changes to Fabric data. Unlike TfNotice (USD's built in notification system), RtChangeTracker and Fabric handle change notifications in a non-blocking manner.
usdrt::RtPrimSelection: The RtPrimSelection class represents a subset of a stage's prims, and allows you to efficiently process them on CPU or GPU using the fabric::batch API.
usdrt::RtTokensType: Provides standard set of public tokens for Rt schema. Access via the RtTokens helper accessor.

usdrt::TfToken: Token for efficient comparison, assignment, and hashing of known strings.
usdrt::UsdAPISchemaBase: The base class for all API schemas.
usdrt::UsdAttribute: Scenegraph object for authoring and retrieving numeric, string, and array valued data, sampled over time.
usdrt::UsdClipsAPI: UsdClipsAPI is an API schema that provides an interface to a prim's clip metadata. Clips are a "value resolution" feature that allows one to specify a sequence of usd files (clips) to be consulted, over time, as a source of varying overrides for the prims at and beneath this prim in namespace.
usdrt::UsdCollectionAPI: This is a general purpose API schema, used to describe a collection of heterogeneous objects within the scene. "Objects" here may be prims or properties belonging to prims or other collections. It's an add-on schema that can be applied many times to a prim with different collection names.
usdrt::UsdGeomBasisCurves: BasisCurves are a batched curve representation analogous to the classic RIB definition via Basis and Curves statements. BasisCurves are often used to render dense aggregate geometry like hair or grass.

usdrt::UsdGeomCamera: Transformable camera.
usdrt::UsdGeomCapsule: Defines a primitive capsule, i.e. a cylinder capped by two half spheres, centered at the origin, whose spine is along the specified axis . For any described attribute Fallback Value or Allowed Values below that are text/tokens, the actual token is published and defined in UsdGeomTokens. So to set an attribute to the value "rightHanded", use UsdGeomTokens->rightHanded as the value.
usdrt::UsdGeomCone: Defines a primitive cone, centered at the origin, whose spine is along the specified axis , with the apex of the cone pointing in the direction of the positive axis.
usdrt::UsdGeomCube: Defines a primitive rectilinear cube centered at the origin.
usdrt::UsdGeomCurves: Base class for UsdGeomBasisCurves , UsdGeomNurbsCurves , and UsdGeomHermiteCurves . The BasisCurves schema is designed to be analagous to offline renderers' notion of batched curves (such as the classical RIB definition via Basis and Curves statements), while the NurbsCurve schema is designed to be analgous to the NURBS curves found in packages like Maya and Houdini while retaining their consistency with the RenderMan specification for NURBS Patches. HermiteCurves are useful for the interchange of animation guides and paths.
usdrt::UsdGeomCylinder: Defines a primitive cylinder with closed ends, centered at the origin, whose spine is along the specified axis .
usdrt::UsdGeomGprim: Base class for all geometric primitives.
usdrt::UsdGeomHermiteCurves: This schema specifies a cubic hermite interpolated curve batch as sometimes used for defining guides for animation. While hermite curves can be useful because they interpolate through their control points, they are not well supported by high-end renderers for imaging. Therefore, while we include this schema for interchange, we strongly recommend the use of UsdGeomBasisCurves as the representation of curves intended to be rendered (ie. hair or grass). Hermite curves can be converted to a Bezier representation (though not from Bezier back to Hermite in general).
usdrt::UsdGeomImageable: Base class for all prims that may require rendering or visualization of some sort. The primary attributes of Imageable are visibility and purpose , which each provide instructions for what geometry should be included for processing by rendering and other computations.
usdrt::UsdGeomMesh: Encodes a mesh with optional subdivision properties and features.
usdrt::UsdGeomModelAPI: UsdGeomModelAPI extends the generic UsdModelAPI schema with geometry specific concepts such as cached extents for the entire model, constraint targets, and geometry-inspired extensions to the payload lofting process.
usdrt::UsdGeomMotionAPI: UsdGeomMotionAPI encodes data that can live on any prim that may affect computations involving:
usdrt::UsdGeomNurbsCurves: This schema is analagous to NURBS Curves in packages like Maya and Houdini, often used for interchange of rigging and modeling curves. Unlike Maya, this curve spec supports batching of multiple curves into a single prim, widths, and normals in the schema. Additionally, we require 'numSegments + 2 * degree + 1' knots (2 more than maya does). This is to be more consistent with RenderMan's NURBS patch specification.
usdrt::UsdGeomNurbsPatch: Encodes a rational or polynomial non-uniform B-spline surface, with optional trim curves.
usdrt::UsdGeomPlane: Defines a primitive plane, centered at the origin, and is defined by a cardinal axis, width, and length. The plane is double-sided by default.
usdrt::UsdGeomPointBased: Base class for all UsdGeomGprims that possess points, providing common attributes such as normals and velocities.
usdrt::UsdGeomPointInstancer: Encodes vectorized instancing of multiple, potentially animated, prototypes (object/instance masters), which can be arbitrary prims/subtrees on a UsdStage .
usdrt::UsdGeomPoints: Points are analogous to the RiPoints spec .
usdrt::UsdGeomPrimvarsAPI: UsdGeomPrimvarsAPI encodes geometric "primitive variables", as UsdGeomPrimvar, which interpolate across a primitive's topology, can override shader inputs, and inherit down namespace.
usdrt::UsdGeomScope: Scope is the simplest grouping primitive, and does not carry the baggage of transformability. Note that transforms should inherit down through a Scope successfully - it is just a guaranteed no-op from a transformability perspective.
usdrt::UsdGeomSphere: Defines a primitive sphere centered at the origin.
usdrt::UsdGeomSubset: Encodes a subset of a piece of geometry (i.e. a UsdGeomImageable ) as a set of indices. Currently only supports encoding of face-subsets, but could be extended in the future to support subsets representing edges, segments, points etc.

usdrt::UsdGeomXformCommonAPI: This class provides API for authoring and retrieving a standard set of component transformations which include a scale, a rotation, a scale-rotate pivot and a translation. The goal of the API is to enhance component-wise interchange. It achieves this by limiting the set of allowed basic ops and by specifying the order in which they are applied. In addition to the basic set of ops, the 'resetXformStack' bit can also be set to indicate whether the underlying xformable resets the parent transformation (i.e. does not inherit it's parent's transformation).
usdrt::UsdGeomXformable: Base class for all transformable prims, which allows arbitrary sequences of component affine transformations to be encoded.
usdrt::UsdLuxBoundableLightBase: Base class for intrinsic lights that are boundable.

For any described attribute Fallback Value or Allowed Values below that are text/tokens, the actual token is published and defined in UsdLuxTokens. So to set an attribute to the value "rightHanded", use UsdLuxTokens->rightHanded as the value.

usdrt::UsdLuxListAPI: ///
usdrt::UsdLuxMeshLightAPI: This is the preferred API schema to apply to Mesh type prims when adding light behaviors to a mesh. At its base, this API schema has the built-in behavior of applying LightAPI to the mesh and overriding the default materialSyncMode to allow the emission/glow of the bound material to affect the color of the light. But, it additionally serves as a hook for plugins to attach additional properties to "mesh lights" through the creation of API schemas which are authored to auto-apply to MeshLightAPI.
usdrt::UsdLuxNonboundableLightBase: Base class for intrinsic lights that are not boundable.
usdrt::UsdLuxPluginLight: Light that provides properties that allow it to identify an external SdrShadingNode definition, through UsdShadeNodeDefAPI , that can be provided to render delegates without the need to provide a schema definition for the light's type.
usdrt::UsdLuxPluginLightFilter: Light filter that provides properties that allow it to identify an external SdrShadingNode definition, through UsdShadeNodeDefAPI , that can be provided to render delegates without the need to provide a schema definition for the light filter's type.
usdrt::UsdLuxPortalLight: A rectangular portal in the local XY plane that guides sampling of a dome light. Transmits light in the -Z direction. The rectangle is 1 unit in length. For any described attribute Fallback Value or Allowed Values below that are text/tokens, the actual token is published and defined in UsdLuxTokens. So to set an attribute to the value "rightHanded", use UsdLuxTokens->rightHanded as the value.
usdrt::UsdLuxRectLight: Light emitted from one side of a rectangle. The rectangle is centered in the XY plane and emits light along the -Z axis. The rectangle is 1 unit in length in the X and Y axis. In the default position, a texture file's min coordinates should be at (+X, +Y) and max coordinates at (-X, -Y). For any described attribute Fallback Value or Allowed Values below that are text/tokens, the actual token is published and defined in UsdLuxTokens. So to set an attribute to the value "rightHanded", use UsdLuxTokens->rightHanded as the value.

But, it additionally serves as a hook for plugins to attach additional properties to "volume lights" through the creation of API schemas which are authored to auto-apply to VolumeLightAPI.
usdrt::UsdMediaSpatialAudio: The SpatialAudio primitive defines basic properties for encoding playback of an audio file or stream within a USD Stage. The SpatialAudio schema derives from UsdGeomXformable since it can support full spatial audio while also supporting non-spatial mono and stereo sounds. One or more SpatialAudio prims can be placed anywhere in the namespace, though it is advantageous to place truly spatial audio prims under/inside the models from which the sound emanates, so that the audio prim need only be transformed relative to the model, rather than copying its animation.

For floating articulations, this should be on the root body. For fixed articulations (robotics jargon for e.g. a robot arm for welding that is bolted to the floor), this API can be on a direct or indirect parent of the root joint which is connected to the world, or on the joint itself..
usdrt::UsdPhysicsCollisionAPI: Applies collision attributes to a UsdGeomXformable prim. If a simulation is running, this geometry will collide with other geometries that have PhysicsCollisionAPI applied. If a prim in the parent hierarchy has the RigidBodyAPI applied, this collider is a part of that body. If there is no body in the parent hierarchy, this collider is considered to be static.

Setting these as a multipleApply schema TfToken name will define the degree of freedom the DriveAPI is applied to. Each drive is an implicit force-limited damped spring: Force or acceleration = stiffness * (targetPosition - position)
usdrt::UsdPhysicsFilteredPairsAPI: API to describe fine-grained filtering. If a collision between two objects occurs, this pair might be filtered if the pair is defined through this API. This API can be applied either to a body or collision or even articulation. The "filteredPairs" defines what objects it should not collide against. Note that FilteredPairsAPI filtering has precedence over CollisionGroup filtering.
usdrt::UsdPhysicsFixedJoint: Predefined fixed joint type (All degrees of freedom are removed.)
usdrt::UsdPhysicsJoint: A joint constrains the movement of rigid bodies. Joint can be created between two rigid bodies or between one rigid body and world.

PhysicsLimitAPI is a multipleApply schema: The PhysicsJoint can be restricted along "transX", "transY", "transZ", "rotX", "rotY", "rotZ", "distance". Setting these as a multipleApply schema TfToken name will define the degree of freedom the PhysicsLimitAPI is applied to. Note that if the low limit is higher than the high limit, motion along this axis is considered locked.

For any described attribute Fallback Value or Allowed Values below that are text/tokens, the actual token is published and defined in UsdPhysicsTokens. So to set an attribute to the value "rightHanded", use UsdPhysicsTokens->rightHanded as the value.
usdrt::UsdPhysicsRigidBodyAPI: Applies physics body attributes to any UsdGeomXformable prim and marks that prim to be driven by a simulation. If a simulation is running it will update this prim's pose. All prims in the hierarchy below this prim should move accordingly.
usdrt::UsdPhysicsScene: General physics simulation properties, required for simulation.
usdrt::UsdPhysicsSphericalJoint: Predefined spherical joint type (Removes linear degrees of freedom, cone limit may restrict the motion in a given range.)

usdrt::UsdRenderPass: A RenderPass prim encapsulates the necessary information to generate multipass renders. It houses properties for generating dependencies and the necessary commands to run to generate renders, as well as visibility controls for the scene.
