ludus::foundation::math::Matrix4d¶

Struct

Column-major 4x4 double-precision matrix used for offline and tooling transforms.

Storage matches Matrix4 (column c, row r at Elements[4 * c + r]); default is zero, not identity. Equality is element-wise IEEE comparison, so -0.0 equals 0.0 and NaN is never equal.
