Detailed Description

Describes an icon marker. The icon will be displayed at the point associated. This descriptor will instanciate a VgIconMarker after the call to VgEngine::VgInstanceFactory::instantiate(VgPointDescriptor const&)

...
VgApplication::VgIApplication* mVgApplication;
VgEngine::VgRefPtr< VgEngine::VgITexture > mTexture;
...

// Allocate a VgIconMarkerDescriptor object
VgEngine::VgRefPtr< Vg3DModule::VgIconMarkerDescriptor > lIconMarkerDescriptor = Vg3DModule::VgIconMarkerDescriptor::create();

// Change the scale
lIconMarkerDescr.mScale = 10.f;
lIconMarkerDescr.mIcon = mTexture.get();

Member Function Documentation

static VgEngine::VgRefPtr< Vg3DModule::VgIconMarkerDescriptor > Vg3DModule::VgIconMarkerDescriptor::create ( )

static

This static method returns a new heap-allocated descriptor. It is the only method that should be used to instantiate new descriptors. It is a way to make sure no one will delete it, except the last VgRefPtr pointing to it.

const VgMarkerType Vg3DModule::VgIconMarkerDescriptor::getType ( ) const

inlinevirtual

Returns

the type of marker

Implements Vg3DModule::VgMarkerDescriptor.

References Vg3DModule::eVgMarkerIcon.

Member Data Documentation

VgEngine::VgColor Vg3DModule::VgIconMarkerDescriptor::mColor = {1.0f, 1.0f, 1.0f, 1.0f}

Color to apply to the marker. Default is fully opaque white. The provided color will be multiplied with the color from the icon's image.

Version

2.1.19

VgEngine::VgRefPtr< VgEngine::VgITexture > Vg3DModule::VgIconMarkerDescriptor::mIcon

The icon's texture. if mIcon is NULL, then the marker and the point will still be created use VgIconMarker::setIcon() to update it later.

Note

When added to the screen, the icon's pixel size is independant from its distance to the camera.

float Vg3DModule::VgIconMarkerDescriptor::mScale

Controls the size of the VgIconMarker in meters if the Vg3DModule::VgPointDescriptor::mSizePolicy is VgEngine::eVgSizePolicyConstantScale, by default 1.0. if Vg3DModule::VgPointDescriptor::mSizePolicy is VgEngine::eVgSizePolicyFitRectangle, will only impact the size relationship of the text marker to other markers on the VgPoint if any. The visible size is also determined by the distance of the POI from the camera (Vg3DModule::VgPointDescriptor::mGeometryConstantSizeDistance) as well as the scale of the VgPoint (Vg3DModule::VgGeometryDescriptor::mScale).

Version

2.1.0 changed default from 70.0 to 1.0, updated documentation.
