Constructor.

Instance methods

Pt	Add(double x = 0, double y = 0, double z = 0)	Moves this point/vector by the specified amount in 3D space.
double	Distance(Pt other)	Calculates the distance between two points in 3D space. (see also remarks)
double	Dot(Pt other)	Calculates the vector dot product.
bool	Equals(object obj) Overrides: object.Equals(object)	Refer to the documentation for object.Equals.
bool	Equals(Pt other) Implements: IEquatable<Pt>.Equals(Pt)	Refer to the documentation for IEquatable<Pt>.Equals.
double[]	GetCameraMatrix(Pt lookingAt, Pt? up = null)	Returns a 3×3 matrix that describes a linear transform that will rotate objects in accordance with the orientation of the camera. This can be passed to Pt.ProjectOntoCamera(Pt, double[]) to project 3D objects into a 2D representation.
int	GetHashCode() Overrides: object.GetHashCode()	Refer to the documentation for object.GetHashCode.
Pt	Normalize()	Scales this vector to make its length equal to 1 (or returns the same vector if it is zero).
PointD	ProjectOntoCamera(Pt cameraPosition, double[] cameraMatrix)	Projects a point onto a 2D canvas using a linear-transformation matrix.
PointD	ProjectOntoCamera(Pt cameraPosition, Pt cameraLookingAt, Pt? cameraUp = null)	Projects a point onto a camera.
Pt	ProjectOntoPlane(Pt planeNormal)	Projects this vector onto the plane that has the specified normal vector.
Pt	Rotate(Pt axisStart, Pt axisEnd, double angle)	Rotates this point counter-clockwise about the specified axis by the specified angle in degrees.
Pt	Scale(double x = 1, double y = 1, double z = 1)	Scales (stretches or shrinks) this point/vector along each axis by the specified multiplicative factors.
Pt	ScaleX(double x)	Scales (stretches or shrinks) this point/vector along the x-axis by the specified multiplicative factor.
Pt	ScaleY(double y)	Scales (stretches or shrinks) this point/vector along the y-axis by the specified multiplicative factor.
Pt	ScaleZ(double z)	Scales (stretches or shrinks) this point/vector along the z-axis by the specified multiplicative factor.
Pt	Set(double? x = null, double? y = null, double? z = null)	Overrides some of the specific coordinates of this point/vector.
string	ToString() Overrides: object.ToString()	Refer to the documentation for object.ToString.
MeshVertexInfo	WithMeshInfo(Pt normal)	Converts this point to a MeshVertexInfo with the specified normal vector.
MeshVertexInfo	WithMeshInfo(double normalX, double normalY, double normalZ)
MeshVertexInfo	WithMeshInfo(Normal befX, Normal afX, Normal befY, Normal afY)	Converts this point to a MeshVertexInfo with the specified normal vector instructions.
VertexInfo	WithNormal(Pt normal)	Converts this point to a vertex with the specified normal vector.
VertexInfo	WithNormal(double x, double y, double z)
VertexInfo	WithTexture(PointD texture)	Converts this point to a vertex with the specified texture coordinates (UV mapping).
VertexInfo	WithTexture(double x, double y)

Operators

Pt	operator+(Pt one, Pt two)	Adds two vectors.
Pt	operator/(Pt one, double two)	Divides a vector by a scalar.
bool	operator==(Pt one, Pt two)	Compares two points/vectors for equality.
