Detailed Description

This class exposes the layer concept. There are two types of layers, one is the type of layers which come from the XML configuration file. This type of layer can't be instantiated except through XML configuration. The other type of layer (called user created layer) may be instantiated by the user through the VgInstanceFactory class using a VgEngine::VgLayer::Descriptor .

Member Function Documentation

float VgLayer.getLoadFactor

(

)

Gets the load factor of the layer. Only applicable on layers created through XML configuration.

Returns

The current load factor.

float VgLayer.getLODFactor

(

)

Gets the LOD factor of the layer. Only applicable on layers created through XML configuration.

Returns

The current LOD factor.

String VgLayer.getName

(

)

Get the layer's name.

Returns

The layer's name.

VgSRSConstRefPtr VgLayer.getSRS

(

)

Returns

The layers SRS

boolean VgLayer.isVisible

(

)

Gets the visibility of the layer.

Returns

true if the layer is visible, false if invisible.

void VgLayer.setHostedVisible

(

boolean

pVisible

)

Sets the visibility of hosted (i.e. user or database created) visuals.

Parameters

pVisible

If true, the visuals are visible, invisible if false.

void VgLayer.setLoadFactor

(

float

pLoadFactor

)

Sets the load factor of the layer. This will impact how much data is loadeded at a same time. May be a usefull handle to control memory footprint and loading speeds. Higher values will cause more data to be loaded at the same time. Only applicable on layers created through XML configuration.

Parameters

pLoadFactor

The load factor to assign to the layer.

void VgLayer.setLODFactor

(

float

pLODFactor

)

Sets the LOD factor of the layer. This will impact how much data is displayed at a same time. May be a usefull handle to control frame rate. Higher values lead to more geometry being displayed. Only applicable on layers created through XML configuration. Does not affect hosted visuals (e.g. labels).

Parameters

pLODFactor

The LOD factor to assign to the layer.

void VgLayer.setVisible

(

boolean

pIsVisible

)

Sets the overall visibility of the layer.

Parameters

pIsVisible

If true the layer will be visible, invisible if false.
