Member Function Documentation

double RectPatch::dist

(

const Vec3 &

P

)

Get distance from given point to closest point of patch.

Parameters:

P

the point

References sep().

Here is the call graph for this function:

Plane RectPatch::getPlane

(

const Vec3 &

P

)

get the plane further away from the given point

Referenced by CRoughPaddedBlock3D::getClosestPlane().

Here is the caller graph for this function:

bool RectPatch::intersect	(	const Vec3 &	P1,
		const Vec3 &	P2
	)

check if line between 2 points intersects patch

Parameters:

P1	1st point
P2	2nd point

double RectPatch::sep

(

const Vec3 &

P

)

Get (perpendicular) distance from given point. If projection of point onto plane is outside patch return -1

Parameters:

P

the point
