Description

The Simulation 3D Actor Transform Set block sets the actor translation, rotation, and scale in the 3D visualization environment.

The block uses a vehicle-fixed coordinate system that is initially aligned with the inertial world coordinate system.

Coordinate system image showing roll, pitch, and yaw about x, y, and z axes, respectively

Axis	Description
X	Forward direction of the vehicle Roll — Right-handed rotation about X-axis
Y	Extends to the right of the vehicle, initially parallel to the ground plane Pitch — Right-handed rotation about Y-axis
Z	Extends upwards Yaw — Left-handed rotation about Z-axis

Axis

Description

Forward direction of the vehicle

Roll — Right-handed rotation about X-axis

Extends to the right of the vehicle, initially parallel to the ground plane

Pitch — Right-handed rotation about Y-axis

Extends upwards

Yaw — Left-handed rotation about Z-axis

Actors are scene objects that support 3D translation, rotation, and scale. Parts are actor components. Components do not exist by themselves; they are associated with an actor.

Tip

Verify that the Simulation 3D Actor Transform Set block executes before the Simulation 3D Scene Configuration block. That way, Simulation 3D Actor Transform Set prepares the signal data before the Unreal Engine^® 3D visualization environment receives it. To check the block execution order, right-click the blocks and select Properties. On the General tab, confirm these Priority settings:

Simulation 3D Scene Configuration — 0
Simulation 3D Actor Transform Set — -1

For more information about execution order, see Control and Display Execution Order (Simulink).

Actor Setup

Actor name.

Actors are scene objects that support 3D translation, rotation, and scale. Parts are actor components. Components do not exist by themselves; they are associated with an actor.

The block does not support multiple instances of the same actor tag. To refer to the same scene actor when you use the 3D block pairs (e.g. Simulation 3D Actor Transform Get and Simulation 3D Actor Transform Set), specify the same Tag for actor in 3D scene, ActorTag parameter.
