PlaneDouble
Constructs a new plane based on the normal and distance to the origin.- Parameters:
normal
- The plane normald
- The distance to the origin
-
PlaneDouble
Constructs a new plane based on the normal and a point on the plane.- Parameters:
normal
- The normalpoint
- The point on the plane
-
PlaneDouble
Constructs a new plane out of the three given points that are considered to be on the plane. The normal is calculated via a cross product between (point1-point2)x(point2-point3)- Parameters:
point1
- The first pointpoint2
- The second pointpoint3
- The third point
-

set
Sets the plane normal and distance to the origin based on the three given points which are considered to be on the plane. The normal is calculated via a cross product between (point1-point2)x(point2-point3)- Parameters:
point1
- The first pointpoint2
- The second pointpoint3
- The third point
-
set
public void set(double nx, double ny, double nz, double d) Sets the plane normal and distance- Parameters:
nx
- normal x-componentny
- normal y-componentnz
- normal z-componentd
- distance to origin
-
distance
Calculates the shortest signed distance between the plane and the given point.- Parameters:
point
- The point- Returns:
- the shortest signed distance between the plane and the point
-
testPoint
Returns on which side the given point lies relative to the plane and its normal. PlaneSide.Front refers to the side the plane normal points to.- Parameters:
point
- The point- Returns:
- The side the point lies relative to the plane
-
testPoint
Returns on which side the given point lies relative to the plane and its normal. PlaneSide.Front refers to the side the plane normal points to.- Parameters:
x
-y
-z
-- Returns:
- The side the point lies relative to the plane
-
isFrontFacing
Returns whether the plane is facing the direction vector. Think of the direction vector as the direction a camera looks in. This method will return true if the front side of the plane determined by its normal faces the camera.- Parameters:
direction
- the direction- Returns:
- whether the plane is front facing
-
getNormal
- Returns:
- The normal
-
getD
public double getD()- Returns:
- The distance to the origin
-
set
Sets the plane to the given point and normal.- Parameters:
point
- the point on the planenormal
- the normal of the plane
-
set
public void set(double pointX, double pointY, double pointZ, double norX, double norY, double norZ) -
set
Sets this plane from the given plane- Parameters:
plane
- the plane
-
