I am a bit confused about matrices and matrix multiplication in GLSL. It is not clear to me where the entries go.

Let’s say I have a `vec2 v = vec2(1.0f, 2.0f);`

and a matrix `mat2 m = mat2(1.0f, 2.0f, 0.0f, 1.0f);`

I can multiply those two together `v = m * v;`

I think GLSL interprets vectors as column vectors, which means that the matrices are filled column after column. So the multiplication above is actually [ATTACH=CONFIG]1494[/ATTACH]. Also, this means that a `mat2x3`

is actually would appear as a `3x2 matrix`

in linear algebra, and can be multiplied from the left by a `vec2`

.

Edit: Moreover, we can multiply `matnxm`

times `matkxn`

, in that order.

Is this the right interpretation?
