Detailed Description

This is the base class that represents a drawer that can draw an aspect of the terrain.

To be a terrain drawer, the internalDraw method must be implemented. This method will only be invoked if the drawer has drawing enabled

virtual void DtTerrainDrawer::draw ( const DtTerrainDatabase *  , const DtViewportExtents *  , DtPrimitiveDrawer *  painter  )

virtual

Call in order to draw the particular aspect of the terrain on the supplied painter.

Calls internalDraw to do the actual drawing if the drawingEnabled flag is true

Reimplemented in DtTerrainGdbDrawer.

void DtTerrainDrawer::setDrawingEnabled ( bool  b )

inline

Get/set the drawingEnabled flag.

Changing this flag does not have any immediate effect. By default this flag is true

Implement this feature to do specific terrain drawing.

Implemented in DtTerrainGridLineDrawer, DtTerrainPolygonDrawer, DtTerrainPaperMapDrawer, DtTerrainFeatureDrawer, DtTerrainContourLinesDrawer, and DtCollectionTerrainDrawer.
