Detailed Description

A GUI plugin that demos the ignition::math::Matrix4<T>::LookAt function.

The plugin offers 3 input fields (XYZ) for each of 3 vectors: the position of the eye, the position of the target and the desired up direction. See more documentation on ignition math.

It works with the lookat_demo.world, and expects that world to have 3 models:

  1. "frame": A model representing the resulting frame, the one which "looks at"
  2. "target": A yellow sphere representing the target which is being "looked at"
  3. "desired_z": A single axis, representing the desired Z axis.

◆ Create()

static TPtr Create ( const std::string &  _filename,
const std::string &  _name 
)
inlinestaticinherited

a class method that creates a plugin from a file name.

It locates the shared library and loads it dynamically.

Parameters
[in]_filenamethe path to the shared library.
[in]_nameshort name of the plugin
Returns
Shared Pointer to this class type

◆ GetFilename()

std::string GetFilename ( ) const
inlineinherited

Get the name of the handler.

◆ GetHandle()

std::string GetHandle ( ) const
inlineinherited

Get the short name of the handler.

◆ GetType()

PluginType GetType ( ) const
inlineinherited

Returns the type of the plugin.

Returns
type of the plugin

◆ Load()

void Load ( sdf::ElementPtr  )
virtual

Load function.

Called when a plugin is first created. This function should not be blocking. This function will be called with an empty sdf element when a GUI plugin is loaded via a gui.ini file or via a command line argument.

Parameters
[in]_sdfPointer the the SDF element of the plugin. This is the plugin SDF, <plugin ...>, and its children. It will be an empty element when loaded from INI file or command line argument.

Reimplemented from GUIPlugin.

◆ LoadParam() [1/2]

void LoadParam ( const sdf::ElementPtr &  _sdf,
const std::string &  _name,
V &  _target,
_defaultValue = V() 
) const
inlineprotectedinherited

Load parameter value from _sdf and store it to the given reference, using the supplied default value if the element in _sdf is not found.

A message is written using gzmsg reporting whether the default value was used or not.

Parameters
[in]_sdfThe SDF element of the plugin.
[in]_nameName of a tag inside the SDF.
[out]_targetThe reference to store the param value to.
[in]_defaultValueThe default value.

◆ LoadParam() [2/2]

void LoadParam ( sdf::ElementPtr &  _sdf,
const std::string &  _name,
std::string &  _target,
const char *  _defaultValue 
) const
inlineprotectedinherited

Load parameter value from _sdf and store it to the given reference, using the supplied default value if the element in _sdf is not found.

A message is written using gzmsg reporting whether the default value was used or not. String specialization to allow accepting const char* values for std::string parameters.

Parameters
[in]_sdfThe SDF element of the plugin.
[in]_nameName of a tag inside the SDF.
[out]_targetThe reference to store the param value to.
[in]_defaultValueThe default value.

◆ paintEvent()

virtual void paintEvent ( QPaintEvent *  )
