Struct re_types::datatypes::Mat4x4

pub struct Mat4x4(pub [f32; 16]);

Datatype: A 4x4 Matrix.

Matrices in Rerun are stored as flat list of coefficients in column-major order:

           column 0         column 1         column 2         column 3
       --------------------------------------------------------------------
row 0 | flat_columns[0]  flat_columns[4]  flat_columns[8]  flat_columns[12]
row 1 | flat_columns[1]  flat_columns[5]  flat_columns[9]  flat_columns[13]
row 2 | flat_columns[2]  flat_columns[6]  flat_columns[10] flat_columns[14]
row 3 | flat_columns[3]  flat_columns[7]  flat_columns[11] flat_columns[15]

Tuple Fields

0: [f32; 16]

Flat list of matrix coefficients in column-major order.
