Creating a text shape

The creation of a text shape is similar to the creation of all other REDsdk shapes, except that it uses the CID_REDTextShape value as parameter of the RED::Factory::CreateInstance call:

// Create the text shape:
RED::Object* text = RED::Factory::CreateInstance( CID_REDTextShape );
if( text == NULL )

// Access its RED::ITextShape interface and assign a font to it:
RED::ITextShape* itext = text->As< RED::ITextShape >();
RC_TEST( itext->SetFont( font, iresmgr->GetState() ) );

The text shape will show something only if:

  1. It has a font assigned to it.
  2. It has a string to display!
  3. It's part of the scene graph being drawn.

Strings can be easily added to text shapes:

// Adding a string to display:
RC_TEST( itext->AddString( "MyFirstString!", RED::Vector3( 10.0, 50.0, 100.0 ), RED::TAP_CENTER, iresmgr->GetState() ) );

Then, the text string should appear centered in 3D at the position specified by RED::Vector3( 10.0, 50.0, 100.0 ).
