Function Documentation

◆ CheckPartialPixelZ()

bool CheckPartialPixelZ	(	Slope	slope,
		std::array< int, TILE_SIZE *TILE_SIZE >	expected
	)

Check whether the partial pixel Z values are the expected values.

The arrays are as if the map is rotated 45 degrees counterclockwise.

Parameters

slope	The slope that is to be checked.
expected	The expect partial pixels Z values.

Returns: True iff at all GetPartialPixelZ results are the same as the expected Z-coordinates.

Definition at line 88 of file landscape_partial_pixel_z.cpp.

References GB(), and GetPartialPixelZ().

◆ CheckPartialPixelZSlopeAddition()

bool CheckPartialPixelZSlopeAddition	(	Slope	slope_expected,
		Slope	slope_a,
		Slope	slope_b
	)

Check whether the addition of two slope's GetPartialPixelZ values results in the GetPartialPixelZ values of the expected slope.

This iterates over all sub-pixel locations within a single tile.

Parameters

slope_expected	The slope that is expected.
slope_a	The first slope of the addition.
slope_b	The second slope of the addition.

Returns: True iff at all GetPartialPixelZ results are the same for each sub-tile position.
