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
Vg3DModule::VgIconMarkerDescriptor lIconMarkerDescr;

// 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.

Member Data Documentation

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

The icon's texture.

Note

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

float Vg3DModule::VgIconMarkerDescriptor::mScale

Scales the icon (which sides always mesure 1x1 meter), by default 70.0.

The visible size can also be determined by the distance of the VgPoint from the camera, see the property VgPointDescriptor::mGeometryConstantSizeDistance for further explanation.
