    Description

    Use the sim3d.vehicle.space.SmallSatSpacecraft object to implement an SmallSat (Aerospace Blockset) spacecraft in a 3D visualization environment using translation and rotation to place the spacecraft.

    Creation

    Description

    smallsat = sim3d.vehicle.space.SmallSatSpacecraft() creates a spacecraft object in the 3D environment in the Unreal Engine® with a default name.

    Object Functions

    Algorithms

    The sim3d.vehicle.space.SmallSatSpacecraft object input uses the aircraft north-east-down (NED) right-handed (RH) Cartesian coordinate system.

    • X-axis — Along aircraft longitudinal axis, points forward

    • Y-axis — Along aircraft lateral axis, points to the right

    • Z-axis — Points downward

    For more information, see Coordinate Systems for Navigation.

    Unreal® uses a skeleton, bones, and mesh to define a 3D model. A skeleton is comprised of a set of bones. A mesh is the outer covering of the skeleton. Aircraft parts are sections of the mesh, such as ailerons or wheels, which are linked to the bones. For more information, see https://docs.unrealengine.com/4.27/AnimatingObjects/SkeletalMeshAnimation/Skeleton/ and Aerospace Skeletons.
