Detailed Description

This class is a terrain texturing decorator that supports the mapping of geospecific images onto terrain tiles.

A user may add as many geospecific images as they wish and the appropriate image region will be loaded and assigned to the terrain tile as needed.

Member Function Documentation

void dtTerrain::GeoTiffDecorator::OnLoadTerrainTile

(

PagedTerrainTile &

tile

)

[virtual]

Based on the currently registered geo tiff images, this method will generate a base texture and assign it to the tile.

Implements dtTerrain::TerrainDecorationLayer.

virtual osg::Node* dtTerrain::GeoTiffDecorator::GetOSGNode

(

)

[inline, virtual]

Since this decorator does not add any geometry to the terrain, just return NULL here.

Implements dtTerrain::TerrainDecorationLayer.

void dtTerrain::GeoTiffDecorator::AddGeoSpecificImage

(

const std::string &

fileName

)

[inline]

Adds a new geo tiff image to the decorator.

void dtTerrain::GeoTiffDecorator::LoadAllGeoSpecificImages

(

)

Loads any images in the image list.

osg::Image * dtTerrain::GeoTiffDecorator::CalculateBaseImage	(	int	lat,
		int	lon
	)

Calculates an image based on the curret geospecific image set.

Parameters:

	lat	The latitude to build an image for.
	lon	The longitude to build an image for.

void dtTerrain::GeoTiffDecorator::SetResultingImageDimensions	(	unsigned int	w,
		unsigned int	h
	)			[inline]

Sets the image dimensions for the resulting terrain tile base texture.
