distance()

float inviwo::Plane::distance

(

const vec3 &

x

)

const

Return signed distance from plane to point, i.e. dot(x - p, normal).

 Plane
   |
   p-> normal

x <-—|-—> x (point) -d d

Returns

Negative distance if behind plane, positive otherwise.

getIntersection()

IntersectionResult inviwo::Plane::getIntersection	(	const vec3 &	start,
		const vec3 &	stop
	)		const

Get intersection point with plane and line segment. Intersects if plane is in between start and stop. Segement start point will be returned if segment lies in the plane.

Returned intersection point is invalid if no intersection exist.

Parameters

start	Start point of segment
stop	End point of segment

Returns

Intersected point and true if intersecting.

isInside()

bool inviwo::Plane::isInside

(

const vec3 &

point

)

const

Check if point is on positive side of plane.

         Plane
           |
           |-> normal
 (outside) |  (inside)

Parameters

point

to check

Returns

true if on positive side of normal or on the plane, otherwise false

projectPoint()

vec3 inviwo::Plane::projectPoint

(

const vec3 &

x

)

const

Project point onto plane. Plane | |-> normal projection |<-— x (point)

Parameters

x	Point to project

Returns

point on the plane
