awayDirection()

QVector2D M2M_Private::SideTools::awayDirection

(

SideDirection

side

)

awayDirection Computes the "away" direction for a side on a tile, in XZ coordinates.

Parameters

side	The direction a side is facing.

Returns

NORTH -> (0, -1) EAST -> (1, 0) SOUTH -> (0, 1) WEST -> (-1, 0)

makeTopQuadFragment()

M2M::Quad M2M_Private::SideTools::makeTopQuadFragment	(	SideDirection	side,
		QVector2D	quadCenter,
		QVector2D	minusQuadCenter,
		float	minusQuadSize,
		M2M::ImageInfo	quadImage,
		M2M::PhongInfo	quadMaterial
	)

makeTopQuadFragment Creates a fragment of a top-facing quad.

Parameters

side	Which fragment? (there are 4!)
quadCenter	Center in XZ coordinates of the quad. The quad is assumed to be size (1, 1).
minusQuadCenter	Center in XZ coordinates of the quad that is subtracted.
minusQuadSize	Size of the subtracted quad (so it is assumed a square).
quadImage	Texture for the main quad.
quadMaterial	Material for the main quad.
