Transform Methods |
The Transform type exposes the following members.
Name | Description | |
---|---|---|
Affineize |
Replaces the last row with (0 0 0 1), discarding any perspective part of this transform
| |
ChangeBasis(Plane, Plane) |
Computes a change of basis transformation. A basis change is essentially a remapping
of geometry from one coordinate system to another.
| |
ChangeBasis(Vector3d, Vector3d, Vector3d, Vector3d, Vector3d, Vector3d) |
Computes a change of basis transformation. A basis change is essentially a remapping
of geometry from one coordinate system to another.
| |
Clone |
Returns a deep copy of the transform. For languages that treat structures as value types, this can
be accomplished by a simple assignment.
| |
CompareTo |
Compares this transform with another transform.
M33 has highest value, then M32, etc.. | |
DecomposeAffine(Transform, Vector3d) |
Decomposes an affine transformation.
A transformation is affine if it is valid and its last row is [0, 0, 0, 1].
An affine transformation can be broken into a linear transformation and a translation.
Note, a perspective transformation is not affine.
| |
DecomposeAffine(Vector3d, Transform) |
Decomposes an affine transformation.
A transformation is affine if it is valid and its last row is [0, 0, 0, 1].
An affine transformation can be broken into a linear transformation and a translation.
Note, a perspective transformation is not affine.
| |
DecomposeAffine(Vector3d, Transform, Transform, Vector3d) |
An affine transformation can be decomposed into a Symmetric, Rotation and Translation.
Then the Symmetric component may be further decomposed as non-uniform scale in an orthonormal
coordinate system.
| |
DecomposeRigid |
Decomposes a rigid transformation. The transformation must be affine.
| |
DecomposeSimilarity |
Decomposes a similarity transformation. The transformation must be affine.
A similarity transformation can be broken into a sequence of a dilation, translation, rotation, and a reflection.
| |
DecomposeSymmetric |
A Symmetric linear transformation can be decomposed A = Q * Diag * Q ^ T, where Diag is a diagonal
transformation. Diag[i][i] is an eigenvalue of A and the i-th column of Q is a corresponding
unit length eigenvector. Note, this transformation must be Linear and Symmetric.
| |
DecomposeTextureMapping |
Decomposition of a uvw transform into components
| |
Diagonal(Vector3d) |
Constructs a new transformation with diagonal (d0,d1,d2,1.0).
| |
Diagonal(Double, Double, Double) |
Constructs a new transformation with diagonal (d0,d1,d2,1.0).
| |
Equals(Object) |
Determines if another object is a transform and its value equals this transform value.
(Overrides ValueTypeEquals(Object).) | |
Equals(Transform) |
Determines if another transform equals this transform value.
| |
GetEulerZYZ |
Find the Euler angles for a rotation transformation.
| |
GetHashCode |
Gets a non-unique hashing code for this transform.
(Overrides ValueTypeGetHashCode.) | |
GetQuaternion |
If this transform is a proper rotation, then find the equivalent quaternion.
| |
GetType | Gets the Type of the current instance. (Inherited from Object.) | |
GetYawPitchRoll |
Find the Tait-Byran angles (also loosely called Euler angles) for a rotation transformation.
| |
IsRigid |
Gets a value indicating whether or not the Transform is rigid.
A rigid transformation can be broken into a proper rotation and a translation,
while an isometry transformation could also include a reflection.
| |
IsSimilarity |
Gets a value indicating whether or not the Transform maintains similarity.
A similarity transformation can be broken into a sequence of a dilation, translation, rotation, and a reflection.
| |
IsZeroTransformationWithTolerance |
True if all values are 0 within tolerance, except for M33 which is exactly 1.
| |
Linearize |
Affinitize() and replaces the last column with (0 0 0 1)^T, discarding any translation part of this transform.
| |
Mirror(Plane) |
Constructs a new Mirror transformation.
| |
Mirror(Point3d, Vector3d) |
Create mirror transformation matrix
The mirror transform maps a point Q to
Q - (2*(Q-P)oN)*N, where
P = pointOnMirrorPlane and N = normalToMirrorPlane.
| |
Multiply |
Multiplies (combines) two transformations.
This is the same as the * operator between two transformations. | |
Orthogonalize |
Force the linear part of this transformation to be a rotation (or a rotation with reflection).
Use DecomposeRigid(T,R) to find the nearest rotation.
| |
PlanarProjection |
Constructs a projection transformation.
| |
PlaneToPlane |
Create a rotation transformation that orients plane0 to plane1. If you want to orient objects from
one plane to another, use this form of transformation.
| |
ProjectAlong |
Construct a projection onto a plane along a specific direction.
| |
Rotation(Double, Point3d) |
Constructs a new rotation transformation with specified angle and rotation center. The axis of rotation is ZAxis.
| |
Rotation(Double, Vector3d, Point3d) |
Constructs a new rotation transformation with specified angle, rotation center and rotation axis.
| |
Rotation(Vector3d, Vector3d, Point3d) |
Constructs a new rotation transformation with start and end directions and rotation center.
| |
Rotation(Double, Double, Vector3d, Point3d) |
Constructs a new rotation transformation with specified angle, rotation center and rotation axis.
| |
Rotation(Vector3d, Vector3d, Vector3d, Vector3d, Vector3d, Vector3d) |
Constructs a transformation that maps X0 to X1, Y0 to Y1, Z0 to Z1.
The frames should be right hand orthonormal frames (unit vectors with Z = X x Y).
The resulting rotation fixes the origin (0,0,0), maps initial X to final X,
initial Y to final Y, and initial Z to final Z.
| |
RotationZYX |
Create rotation transformation From Tait-Byran angles (also loosely known as Euler angles).
| |
RotationZYZ |
Create rotation transformation From Euler angles.
| |

bounding box that contains the transformed result of its 8 original corner
points.
