occtl_transform_t Struct Reference

#include <occtl_geom.h>

Public Attributes
double	m [12]

Detailed Description

3-by-4 affine transform, row-major, double precision.

Represents the linear part and translation of an affine map from 3D to 3D. Layout (row indices 0–2, column indices 0–3):

m[0..3]  — row 0: [a00 a01 a02 tx]
m[4..7]  — row 1: [a10 a11 a12 ty]
m[8..11] — row 2: [a20 a21 a22 tz]

The implicit last row is [0 0 0 1]. occtl_transform_identity returns a valid identity transform. The rotation sub-matrix is not guaranteed orthonormal unless the transform was produced by occtl_transform_rotation or composed from other valid transforms.
