Constructor Detail

TextureManager

public TextureManager(DirectByteBufferPool directByteBufferPool,
                      TextureTileManager tileManager,
                      double[] translationToLocalCRS,
                      int maxFragmentTexturesInGPUMemory,
                      int requestTimeout)

Parameters:

directByteBufferPool - to be used for the textures

tileManager - managing all tiles

translationToLocalCRS - the translation vector

maxFragmentTexturesInGPUMemory -

requestTimeout - in miliseconds

public double getMatchingResolution(double unitsPerPixel)

Parameters:

unitsPerPixel -

Returns:

the matching resolution

getTextures

public Map<RenderMeshFragment,FragmentTexture> getTextures(RenderContext glRenderContext,
                                                           float maxProjectedTexelSize,
                                                           Set<RenderMeshFragment> fragments)

Retrieves view-optimized textures for the RenderMeshFragments.

Parameters:
