Detailed Description

Runtime implementation of a GlsVideoToTexture

Constructor & Destructor Documentation

◆ GlsVideoToTexture() [1/2]

GlsVideoToTexture ( bool  generateInstance = false)

Constructor

Parameters
generateInstanceWhether or not to generate an instance name for this object.

◆ GlsVideoToTexture() [2/2]

GlsVideoToTexture ( const GlsVideoToTexture that,
const bool  generateNames 
)

Copy constructor

Parameters
thatThe object to copy from.
generateNamesWhether or not to generate an instance name for this object.

◆ ~GlsVideoToTexture()

virtual ~GlsVideoToTexture ( )
virtual

Destructs a GlsVideoToTexture object

Member Function Documentation

◆ CaptureDevice() [1/2]

virtual int CaptureDevice ( )
virtual
Returns
The current capture device index.

◆ CaptureDevice() [2/2]

virtual void CaptureDevice ( const int &  value)
virtual

Sets the desired capture device index.

Parameters
valueThe new capture device index to set.

◆ CloneObject()

virtual DisplayObject * CloneObject ( bool  generateNames = false)
virtual

Copy+Create operation in one method. In derived classes, this method will create a new instance of the derived class and then copy the object into the new instance. The cut,copy,paste and undo operations use this method.

Parameters
generateNamesWhether or not to generate new names for cloned objects
Returns
A new object, identical to the original, except for the instance name

Reimplemented from GLPolygon.

◆ CopyProperties()

virtual void CopyProperties ( DisplayObject src)
virtual

Copies the attributes except for geometry attributes from one object to another. Used by the undo mechanism to undo most attribute change operations.

Parameters
srcThe object to copy properties from

Reimplemented from DisplayObject.

◆ CreateInstance()

static DisplayObject * CreateInstance ( )
static
Returns
A pointer to a new GlsVideoToTexture object.

◆ Draw()

virtual void Draw ( )
virtual

Draws this object on the current display frame (_parent member).

Reimplemented from GLPolygon.

◆ GetCppInterfaceDescription()

virtual InterfaceListType * GetCppInterfaceDescription ( InterfaceListType addToThisList = NULL)
virtual

Get the details of the Cpp Interface The actual interface is exposed in compiled code.

Parameters
addToThisListIf not NULL this list will be added to then returned. If NULL a new list will be created.
Returns
A templated list.
The caller must call the corresponding free method to safely free the memory.

Reimplemented from DisplayObject.

◆ GetCppInterfaceDescriptionFree()

virtual void GetCppInterfaceDescriptionFree ( InterfaceListType array)
virtual

Frees the memory allocated by a previous call to GetCppInterfaceDescription

Parameters
arrayMemory allocated by a previous call to GetCppInterfaceDescription

Reimplemented from DisplayObject.

◆ NumUpdateBlocks() [1/2]

virtual int NumUpdateBlocks ( )
virtual
Returns
The number of execution frames required to update.

◆ NumUpdateBlocks() [2/2]

virtual void NumUpdateBlocks ( const int &  value)
virtual

Specifies how many execution frames required to update on texture. 1 == Full update in one frame.

Parameters
valueThe new number of execution frames.

◆ PreDraw()

virtual void PreDraw ( const OpenGLMatrices current,
Culler culler 
)
virtual

Traverses the hierarchy calculating the _modelMatrix, _projMatrix, _viewMatrix as needed.

Parameters
currentCurrent matrices inherited from parent
cullerObject that possibly marks this object for culling

Reimplemented from DisplayObject.

◆ SetAvailableAttributes()

virtual void SetAvailableAttributes ( unsigned int  value)
virtual

Specifies which attributes are available for the object. Currently the available attributes cannot be changed after they have been set. (Only the first call has an effect.)

Parameters
valueA bitfield specifying which types of attributes to make available.
See also
AvailableAttributesEnum

Reimplemented from DisplayObject.

◆ SetValue()

virtual void SetValue ( int  spec,
va_list &  args 
)
virtual

Sets an attribute of this object using variable arguments

Parameters
specA GLS_Initializer tag
argsA variable argument list

Reimplemented from DisplayObject.
