Detailed Description

Being rendered, the elements modifies current model-view matrix such that the axes of the specified reference system (in model space) become oriented in the following way:

• X - heads to the right side of view.
• Y - heads to the up side of view.
• N(Z) - heads towards the screen. Originally, this element serves for need of flipping the 3D text of dimension presentations.

Constructor & Destructor Documentation

OpenGl_Flipper()

OpenGl_Flipper::OpenGl_Flipper

(

const gp_Ax2 &

theReferenceSystem

)

Construct rendering element to flip model-view matrix along the reference system to ensure up-Y, right-X orientation.

Parameters

[in]

theReferenceSystem

the reference coordinate system.

Member Function Documentation

DumpJson()

void OpenGl_Flipper::DumpJson ( Standard_OStream & theOStream, int theDepth = -1 ) const

overridevirtual

Dumps the content of me into the stream.

Reimplemented from OpenGl_Element.

Release()

void OpenGl_Flipper::Release ( OpenGl_Context * theContext )

overridevirtual

Release GPU resources. Pointer to the context is used because this method might be called when the context is already being destroyed and usage of a handle would be unsafe.

Implements OpenGl_Element.

Render()

void OpenGl_Flipper::Render ( const occ::handle< OpenGl_Workspace > & theWorkspace ) const

overridevirtual

Implements OpenGl_Element.

SetOptions()

void OpenGl_Flipper::SetOptions ( const bool theIsEnabled )

inline

Set options for the element.

Parameters

[in]

theIsEnabled

flag indicates whether the flipper matrix modification should be set up or restored back.
