Detailed Description

Represents a generic 3*3 matrix.

It is defined in a row-major order, it means that, in the value buffer, the entire first row is stored first, followed by the entire second row, and so on. You can access the data with the 'r' ptr or by element attribute.

Parameters
rotation: the Matrix3f to compute the transpose from.
Returns
The transpose of the given Matrix3f

◆ set_identity()

def set_identity (   self)

Sets the Matrix3f to identity.

Returns
itself

◆ identity()

def identity (   self)

Creates an identity Matrix3f  .

Returns
a Matrix3f set to identity
