* matrix notation used in opengl documentation does not describe in-memory layout for OpenGL matrices
Translation matrix should be laid out in memory like this:
{ 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, trabsX, transY, transZ, 1 }
9.005 Are OpenGL matrices column-major or row-major?
For programming purposes, OpenGL matrices are 16-value arrays with base vectors laid out
contiguously in memory. The translation components occupy the 13th, 14th, and 15th elements
of the 16-element matrix, where indices are numbered from 1 to 16 as described in section
For programming purposes, OpenGL matrices are 16-value arrays with base vectors laid out
contiguously in memory. The translation components occupy the 13th, 14th, and 15th elements
of the 16-element matrix, where indices are numbered from 1 to 16 as described in section
2.11.2 of the OpenGL 2.1 Specification.
Column-major versus row-major is purely a notational convention. Note that post-multiplying
with column-major matrices produces the same result as pre-multiplying with row-major matrices.
The OpenGL Specification and the OpenGL Reference Manual both use column-major notation.
