Functions

func DDAPolygon

func DDAPolygon(polygon geom.Polygon, pixel func(x, y int))

func DDAPolygonBlocks

func DDAPolygonBlocks(polygon geom.Polygon, blockSize int, line func(x0, x1, y int), block func(x, y int))

func DDATriangle

func DDATriangle(triangle geom.Triangle, pixel func(x, y int))

DDATriangle calls function pixel for each pixel a geom.Triangle covers.

func DDATriangleBlocks

func DDATriangleBlocks(triangle geom.Triangle, blockSize int, line func(x0, x1, y int), block func(x, y int))

DDATriangleBlocks calls function line for each line a triangle covers, and calls function block for each block the triangle covers.

func DDATriangleLines

func DDATriangleLines(triangle geom.Triangle, line func(x0, x1, y int))

DDATriangleLines calls function line for each horizontal line a geom.Triangle covers using a digital differential analyzing algorithm.
