OpenMaya.MPoint Class Reference

Class Description

3D point with double-precision coordinates.

Constructors

SignatureParametersDescription
MPoint()  

Default constructor. Returns a new MPoint object, initialized to the origin.

MPoint(src) src - MPoint, MFloatPoint, MVector or MFloatVector

Copy constructor. Returns a new MPoint object with its x, y, z and w coords set to the same values as src. If src is a vector then the new MPoint's w coordinate is set to 1.0.

MPoint(seq) seq - sequence of two, three or four floats

Returns a new MPoint object whose x, y, z and w coordinates are set to the elements of seq. If the sequence contains fewer than four values w will be set to 1.0. If the sequence contains fewer than three values z will be set to 0.0.

MPoint(x, y, z=0.0, w=1.0) x - float
y - float
z - float
w - float
Returns a new MPoint object with the specified x, y, z and w coordinates.

Sequence Support

An MPoint is treated a sequence of four float values: [x, y, z, w].

len() returns 4.

Indexing and element assignment are supported.

Deletion, concatenation, repetition and slicing are not supported.

Number Support

Operation

Description

MPoint = MPoint + MVector

Addition of a vector to a point.

MPoint += MVector

In-place addition of a vector to the point. Returns a new reference to the point.

MPoint = MPoint - MVector

Subtraction of a vector from a point.

MPoint -= MVector

In-place subtraction of a vector from a point. Returns a new reference to the point.

MVector = MPoint - MPoint

Vector difference between two points.

MPoint = MMatrix* MPoint

Pre-multiplication of a point by a matrix.

MPoint = MPoint * MMatrix

Post-multiplication of a point by a matrix.

MPoint *= MMatrix

In-place post-multiplication of a point by a matrix. Returns a new reference to the point.

MPoint = MPoint * scalar

Multiplication of a point by a scalar. The scalar must be convertable to float.

MPoint = MPoint / scalar

Division of a point by a scalar. The scalar must be convertable to float.

Comparison Support

MPoint == MPoint Returns True if each component of the first point is exactly equal to the corresponding component of the second.
MPoint != MPoint Returns False is any component of the first point is not exactly equal to the corresponding component of the second.

All other comparison operators will raise a TypeError exception.
