From Solid Graphics Wiki
The Planed class represents a plane. The plane is specified by the plane's normal vector and it's distance from the coordinate system origin (by the offset field). The Plane class uses double precision.
Constructors
Default Planed class constructor does not initialize the plane fields to any value. This is on purpose for performance reasons. Other class costructors allow to initialize the Planed object from other plane, vector and a offset, or four double values.
Fields
| Field name
| Type
| Description
|
| x
| double
| (inherited from the Vectord class) the X coordinate of planes normal vector
|
| y
| double
| (inherited from the Vectord class) the Y coordinate of planes normal vector
|
| z
| double
| (inherited from the Vectord class) the Z coordinate of planes normal vector
|
| offset
| double
| plane's distance value from the coordinate system origin (0, 0, 0). (The offset represents the distance correctly only if plane's normal vector's length is 1 )
|
Methods
| Create
| Creates the plane from plane normal vector and a point which is part of the plane, or a three points lying in the plane.
|
| RecalculateOffset
| Recalculates the offset field to include specified point.
|
| Normalize
| Scales the plane values so its' normal vector's length is 1.
|
| Scale
| Scales the plane values by specified factor.
|
| Distance
| Returns distance of specified point to the plane.
|
| GetUVVectors
| Returns two non-parallel vectors which lie inside of the plane.
|
| ClosestPlanePoint
| Returns point which lies inside the plane and is closest to the specified point.
|
| VectorProjection
| Returns vector which is projection of specified vector to the plane's normal vector.
|
Operators
| *
| Returns a plane equal to the plane instance scaled by the operand.
|
| =
| assigns a vector to the plane. The offset field is initialized to value 0.0f.
|
| *=
| Scales the plane by specified operand.
|
| /=
| Divides the vector by specified operand
