Transform Properties |
The Transform type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | Determinant |
The determinant of this 4x4 matrix.
|
 | Identity |
Gets a new identity transform matrix. An identity matrix defines no transformation.
|
| IsAffine |
Tests for 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.
|
| IsIdentity | Return true if this Transform is the identity transform |
| IsLinear |
Tests for a linear transformation.
A transformation is affine if it is valid and its last row is [0, 0, 0, 1].
If in addition its last column is ( 0, 0, 0, 1)^T then it is linear.
An affine transformation can be broken into a linear transformation and a translation.
|
| IsRotation |
Returns true if this is a proper rotation.
|
| IsValid |
Gets a value indicating whether or not this Transform is a valid matrix.
A valid transform matrix is not allowed to have any invalid numbers.
|
| IsZero |
True if matrix is Zero4x4, ZeroTransformation, or some other type of
zero. The value xform[3][3] can be anything.
|
| IsZero4x4 |
True if all values are 0
|
| IsZeroTransformation |
True if all values are 0, except for M33 which is 1.
|
| Item |
Gets or sets the matrix value at the given row and column indices.
|
| M00 | Gets or sets this[0,0]. |
| M01 | Gets or sets this[0,1]. |
| M02 | Gets or sets this[0,2]. |
| M03 | Gets or sets this[0,3]. |
| M10 | Gets or sets this[1,0]. |
| M11 | Gets or sets this[1,1]. |
| M12 | Gets or sets this[1,2]. |
| M13 | Gets or sets this[1,3]. |
| M20 | Gets or sets this[2,0]. |
| M21 | Gets or sets this[2,1]. |
| M22 | Gets or sets this[2,2]. |
| M23 | Gets or sets this[2,3]. |
| M30 | Gets or sets this[3,0]. |
| M31 | Gets or sets this[3,1]. |
| M32 | Gets or sets this[3,2]. |
| M33 | Gets or sets this[3,3]. |
| RigidType |
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.
|
| SimilarityType |
Gets a value indicating whether or not the Transform maintains similarity.
The easiest way to think of Similarity is that any circle, when transformed,
remains a circle. Whereas a non-similarity Transform deforms circles into ellipses.
|
| Unset |
Gets an XForm filled with RhinoMath.UnsetValue.
|
| ZeroTransformation |
ZeroTransformation diagonal = (0,0,0,1)
