Method Detail

computeTextureTransform

protected abstract void computeTextureTransform(DrawContext dc,
                                                SurfaceTile tile,
                                                SurfaceTileRenderer.Transform t)

dispose

public void dispose()

Free internal resources held by this surface tile renderer. A GL context must be current when this method is called.

Specified by:

dispose in interface Disposable

Throws:

GLException - - If an OpenGL context is not current when this method is called.

getIntersectingTiles

protected abstract java.lang.Iterable<SurfaceTile> getIntersectingTiles(DrawContext dc,
                                                                        SectorGeometry sg,
                                                                        java.lang.Iterable<? extends SurfaceTile> tiles)

initAlphaTexture

protected void initAlphaTexture(DrawContext dc,
                                int size)

initOutlineTexture

protected void initOutlineTexture(DrawContext dc,
                                  int size)

isShowImageTileOutlines

public boolean isShowImageTileOutlines()

isUseImageTilePickColors

public boolean isUseImageTilePickColors()

Indicates how this SurfaceTileRenderer interprets image tile colors during picking. When true, image tile RGB colors are drawn during picking. When false, image tile RGB colors are replaced with the current RGB color. Initially false.

Returns:

true if image tile RGB colors are drawn during picking, false if image tile RGB colors are replaced by the current RGB color.

preComputeTextureTransform

protected abstract void preComputeTextureTransform(DrawContext dc,
                                                   SectorGeometry sg,
                                                   SurfaceTileRenderer.Transform t)

renderTile

public void renderTile(DrawContext dc,
                       SurfaceTile tile)

renderTiles

public void renderTiles(DrawContext dc,
                        java.lang.Iterable<? extends SurfaceTile> tiles)

setShowImageTileOutlines

public void setShowImageTileOutlines(boolean showImageTileOutlines)

setUseImageTilePickColors

public void setUseImageTilePickColors(boolean useImageTilePickColors)

Specifies how this SurfaceTileRenderer interprets image tile colors during picking. When true, image tile RGB colors are drawn during picking. When false, image tile RGB colors are replaced with the current RGB color.

Parameters:

useImageTilePickColors - true if image tile RGB colors should be drawn during picking, false if image tile RGB colors should be replaced by the current RGB color.
