|
IsConformal | The boolean value that indicates whether this transformation is conformal. |
|
|
IsIdentity | The boolean value that indicates whether this transformation is an identity. |
|
IsReadOnly |
Identifies if the object is read-only or modifiable.
(Inherited from APIObject ) |
|
|
IsTranslation | The boolean value that indicates whether this transformation is a translation. |
|
|
Origin | Defines the origin of the old coordinate system in the new coordinate system. |
|
|
Scale | The real number that represents the scale of the transformation. |
Methods
| Name | Description | |
|---|---|---|
|
AlmostEqual | Determines whether this transformation and the specified transformation are the same within the tolerance (1.0e-09). |
|
|
CreateReflection | Creates a transform that represents a reflection across the given plane. |
|
|
CreateRotation | Creates a transform that represents a rotation about the given axis at (0, 0, 0). |
|
|
CreateRotationAtPoint | Creates a transform that represents a rotation about the given axis at the specified point. |
|
|
CreateTranslation | Creates a transform that represents a translation via the specified vector. |
|
|
Dispose |
Causes the object to release immediately any resources it may be utilizing.
(Inherited from APIObject ) |
|
|
Equals |
Determines whether the specified object is equal to the current object.
(Inherited from Object ) |
|
|
GetHashCode |
Serves as the default hash function.
(Inherited from Object ) |
|
|
GetType |
Gets the
Type
of the current instance.
(Inherited from Object ) |
|
|
Multiply | Multiplies this transformation by the specified transformation and returns the result. |
|
|
OfPoint | Applies the transformation to the point and returns the result. |
|
|
OfVector | Applies the transform to the vector |
|
|
ScaleBasis | Scales the basis vectors of this transformation and returns the result. |
|
|
ScaleBasisAndOrigin | Scales the basis vectors and the origin of this transformation and returns the result. |
|
|
ToString |
Returns a string that represents the current object.
(Inherited from Object ) |
Operators
| Name | Description | |
|---|---|---|
|
Multiply(Transform, Transform) | Multiplies the two specified transforms. |
Example
C#
public static XYZ TransformPoint(XYZ point, Transform transform)
{
double x = point.X;
double y = point.Y;
double z = point.Z;
//transform basis of the old coordinate system in the new coordinate // system
XYZ b0 = transform.get_Basis(0);
XYZ b1 = transform.get_Basis(1);
XYZ b2 = transform.get_Basis(2);
XYZ origin = transform.Origin;
//transform the origin of the old coordinate system in the new
//coordinate system
double xTemp = x * b0.X + y * b1.X + z * b2.X + origin.X;
double yTemp = x * b0.Y + y * b1.Y + z * b2.Y + origin.Y;
double zTemp = x * b0.Z + y * b1.Z + z * b2.Z + origin.Z;
return new XYZ(xTemp, yTemp, zTemp);
