Detailed Description

An OrthoGPUProducer layer to blend the tiles of two OrthoGPUProducer.

This layer modifies the tiles of its OrthoGPUProducer producer by blending into them the tiles produced by another OrthoGPUProducer, after they have been transformed via a GPU Program.

Constructor & Destructor Documentation

proland::TextureLayer::TextureLayer ( ptr< TileProducer >  tiles,
ptr< Program >  program,
std::string  tilesSamplerName,
BlendParams  blend,
int  minDisplaylevel,
bool  storeTiles = false 
)

Creates a new TextureLayer.

Parameters:
tiles the producer producing the tiles that must be blended into the tiles produced by the producer to which this layer belongs. The 'tiles' producer must be a GPU producer, but the size and format of its tiles are arbitrary. Its maximum level can also be less than the maximum level of the producer to which this layer belongs (in this cas an automatic zoom is used to produce finer tiles).
program the Program to be used to transform the tiles produced by 'tiles' before bending them into the tiles produced by the producer to which this layer belongs.
tilesSamplerName name of the samplerTile uniform in 'program' that is used to access the tiles produced by 'tiles'.
blend the blend equations and functions to be used to blend the tiles together.
minDisplayLevel the quadtree level at which the display of this layer must start.
virtual proland::TextureLayer::~TextureLayer (  )  [virtual]

Deletes this TextureLayer.

proland::TextureLayer::TextureLayer (  )  [protected]

Creates an uninitialized TextureLayer.

ptr<TileProducer> proland::TextureLayer::tiles [private]
