Aero.Body Class

Namespace: Aero

Create body object for use with animation object

Description

Use the Aero.Body class to create a body object for use with an Aero.Animation object. To use the Aero.Body object, you typically:

  1. Create the animation body.

  2. Configure or customize the body object.

  3. Load the body.

  4. Generate patches for the body. This step requires an axes from a figure.

  5. Set the timeseries data source.

  6. Move or update the body.

By default, an Aero.Body object natively uses aircraft x-y-z coordinates for the body geometry and the timeseries data. It expects the rotation order z-y-x (psi, theta, phi).

Convert timeseries data from other coordinate systems by registering a different CoordTransformFcn function.

The Aero.Body class is a handle class.

Creation

h = Aero.Body constructs a body for an animation object. The animation object is returned in h.

Type of timeseries data stored in 'TimeSeriesSource' property, specified as one of these values:

timeseries TypeDescription

'Array6DoF'

A double-precision array in n rows and seven columns for 6-DoF data: time x y z phi theta psi. If a double-precision array of eight or more columns is in 'TimeSeriesSource', the first seven columns are used as 6-DoF data.

'Timeseries'

MATLAB timeseries data with six values per time:

x y z phi theta psi

The values are resampled.

'Timetable'

MATLAB timetable data with six values per time:

x y z phi theta psi

The values are resampled.

'StructureWithTime'

Simulink struct with time, for example, Simulink root outport logging 'Structure with time':

  • signals(1).values: x y z

  • signals(2).values: phi theta psi

Signals are linearly interpolated versus time using interp1.

'Array3DoF'

A double-precision array in n rows and four columns for 3-DoF data: time x z theta. If a double-precision array of five or more columns is in 'TimeSeriesSource', the first four columns are used as 3-DoF data.

'Custom'

Position and angle data are retrieved from 'TimeSeriesSource' by the currently registered 'TimeseriesReadFcn'.

This example shows how to update the body, b, with time in seconds of 5.

b = Aero.Body;
b.load('pa24-250_orange.ac','Ac3d'); 
tsdata = [ ...
    0,  1,1,1, 0,0,0; ...
    10  2,2,2, 1,1,1; ];
b.TimeSeriesSource = tsdata;
b.update(5);
