Member Function Documentation

f32 core::plane3d::getDistanceTo

(

const vector3d &

point

)

const

Returns the distance to a point. Note that this only works if the normal is Normalized.

References D, core::vector3d::dotProduct(), and Normal.

bool core::plane3d::getIntersectionWithLine	(	const vector3d &	linePoint,
		const vector3d &	lineVect,
		vector3d &	outIntersection
	)		const

Returns an intersection with a 3d line.

Parameters:

lineVect,:	Vector of the line to intersect with.
linePoint,:	Point of the line to intersect with.
outIntersection,:	Place to store the intersection point, if there is one.

References D, core::vector3d::dotProduct(), and Normal.

Referenced by getIntersectionWithPlanes().

bool core::plane3d::getIntersectionWithPlane	(	const plane3d &	other,
		vector3d &	outLinePoint,
		vector3d &	outLineVect
	)		const

Intersects this plane with another.

Parameters:

other,:	Other plane to intersect with.
outLinePoint,:	Base point of intersection line.
outLineVect,:	Vector of intersection.

bool core::plane3d::getIntersectionWithPlanes	(	const plane3d &	o1,
		const plane3d &	o2,
		vector3d &	outPoint
	)		const

Returns the intersection point with two other planes if there is one.

vector3d core::plane3d::getMemberPoint

(

)

const

Returns a member point of the plane.

References D, and Normal.

Referenced by core::matrix4::transformPlane().

bool core::plane3d::isFrontFacing

(

const vector3d &

lookDirection

)

const

Returns if the plane is front of backfacing. Note that this only works if the normal is Normalized.

Parameters:

lookDirection,:

Look direction.

Returns:

Returns true if the plane is front facing, which mean it would be visible, and false if it is backfacing.

void core::plane3d::recalculateD

(

const vector3d &

MPoint

)

Recalculates the distance from origin by applying a new member point to the plane.
