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 Iterable<SurfaceTile> getIntersectingTiles(DrawContext dc,
                                                              SectorGeometry sg,
