Detailed Description

Affine transformation for 3D containing a transformation matrix and a translation vector.

No perspective transformation is possible, only translation, rotation, scaling and shear.

Member Function Documentation

Equals() [1/2]

bool Equals

(

AffineMatrix3D

t2

)

Gets whether this and the other t2 object are equal.

Parameters

t2	Object to compre to.

Returns

true if t2 and this instance represent the same value; otherwise false.

Equals() [2/2]

override bool Equals

(

object

obj

)

Indicates whether this instance and the given obj are equal.

Parameters

obj	Object to compare to.

Returns

true if obj and this instance are the same type and represent the same value; otherwise false.

GetHashCode()

override int GetHashCode

(

)

Returns the hash code for this instance.

Returns

A 32-bit signed integer that is the hash code for this instance.

Inverse()

AffineMatrix3D Inverse

(

)

Gets the inverse of this affine transformation if possible.

Returns

Inverse.

Exceptions

DivideByZeroException

If the matrix cannot be inverted.

Invert()

void Invert

(

)
