MATLAB: Is there a way to use the point-of-view (POV) switch on the joystick with the Joystick Input block in the Aerospace Blockset 2.2 (R2006b)

Aerospace Blocksetinputjoystickofpointpovview

I want to use the POV switch on a joystick to control trimflaps during my simulation.

This bug has been fixed in Release 2007a (R2007a). For previous product releases, read below for any possible workarounds:

To use the POV switch of a joystick with the Pilot Joystick block in Aerospace Blockset:

1. Double-click the Pilot Joystick block.

2. Select the 'Output configuration' popup list. This option enables you to output all signals from the joystick.

3. From the list, select 'AllOutputs' and click OK. The block outputs reflect three ports. Port 3 is for POV.

To implement actions based on signals, you can do one of the following:

With the POV signal, use Enabled or Triggered subsystems to perform actions based on the signal value.
Use If-Else blocks to implement actions based on a signal.

MATLAB: Does Simulink 3D Animation enable the use of more than two input joysticks

Yes, the "Joystick Input" block supports the use of more than 2 joysticks at a time since the parameters allow you to freely specify the "Joystick ID".

I have attached a simple model showing three "Joystick Input" blocks with three different "Joystick IDs".

MATLAB: Is the VRML Animation slow and jerky when using Simulink 3D Animation

There are several reasons that can cause the slow and jerky behavior in a VRML world created using Simulink 3D Animation.

1. Check the sample time for the VR Sink block. It should be explicitly set, not inherited (-1).

2. Ensure that you are using a graphics card with hardware OpenGL acceleration. Check the output of entering the following MATLAB Command to see if you are using a supported graphics card with OpenGL Acceleration.

3. Check the size of the VRML world.

CAD models are usually parametric models that use proprietary object rendering methods for use in various contexts. During VRML model export, the internal parametric model of the assembly is tessellated. In this process, the model surface is divided into triangular meshes, represented in VRML by the "IndexedFaceSet" node. During tesselation, it is important to set the granularity of the mesh so that it is suitable for further use. ~10000 triangles is the limit for smooth performance, but, this will be dependent on the model complexity which is driving the VRML sink. The ">> vr_octavia" is a good benchmark to check the graphics capability on the customer's system.

4. If the Simulink model and the VRML file are both demanding significant computational resources, consider client-server capabilities of Simulink 3D Animation. They will run the model on one computer, but, visualize the animation from a different computer by connecting over TCP/IP and using a remote viewer.
