Constructor & Destructor Documentation

virtual makVrv::DtTextRenderer::~DtTextRenderer ( )

virtual

Member Function Documentation

DtTextRenderer& makVrv::DtTextRenderer::operator= ( const DtTextRenderer &  other )

delete

Assignment Operator not implemented - Assignment not allowed.

virtual DtTextProxy* makVrv::DtTextRenderer::createProxy ( )

virtual

Create a text proxy.

virtual DtTextProxy* makVrv::DtTextRenderer::cloneProxy ( const DtTextProxy *  )

virtual

Clone a text proxy.

virtual int makVrv::DtTextRenderer::numberOfPrimitives ( ) const

virtual

Get the number of Primitives.

Implements makVrv::DtPrimitiveRenderer.

virtual void makVrv::DtTextRenderer::releaseResources ( )

virtual

Release any rendering resources.

Implements makVrv::DtPrimitiveRenderer.

virtual bool makVrv::DtTextRenderer::isRenderModeSupported ( int  mode )

virtual

Get if a render mode is supported.

Implements makVrv::DtPrimitiveRenderer.

virtual bool makVrv::DtTextRenderer::forceTextShaping ( void  ) const

virtual

virtual void makVrv::DtTextRenderer::render ( bool  geocentric, float  geocentricAlpha, const double  location[3], double  altitude, const double  positionMatrix[16], const double  projectionMatrix[16]  )

virtual

Render the text.

virtual void makVrv::DtTextRenderer::addGroupRef ( unsigned  int )

virtual

Add the given group reference to the DtOverlayResourceProvider.

virtual void makVrv::DtTextRenderer::removeGroupRef ( unsigned  int )

virtual

Remove the given group reference from the DtOverlayResourceProvider.

virtual void makVrv::DtTextRenderer::removeProxy ( const DtTextProxy *  )

virtual

Removes a text proxy from this text renderer. This does not delete the text proxy object.

virtual void makVrv::DtTextRenderer::setAltitudeBasedConfigurationsForProxy ( DtTextProxy *  , const DtAltitudeBasedConfigurationCollection &    )

virtual

Set a collection of altitude-based configurations to use for a text proxy. This API allows for the specification of different fonts a text proxy will use based on the altitude of the camera rendering the text proxy.

That is, each frame, the camera's altitude is used to determine the specific altitude-based configuration to use. The altitude-based configuration that meets both of the following conditions will be used: (1) The configuration's base altitude is less than the camera's current altitude. (2) The configuration's base altitude is larger than all other altitude-based configurations, defined for a given text proxy, that also meet condition (1).

Altitude is in meters from mean sea level.

virtual bool makVrv::DtTextRenderer::getAltitudeBasedConfigurationsForProxy ( const DtTextProxy *  , DtAltitudeBasedConfigurationCollection &    ) const

virtual

Get the collection of altitude-based configurations used for a text proxy.

virtual void makVrv::DtTextRenderer::clearAltitudeSpecificConfigurationsForProxy ( DtTextProxy *  )

virtual

Clear the collection of altitude-based configurations for a text proxy, if any.
