Look at me ma, my library is going to have a matrix type, a row vector type and a column vector type, isn't that wonderful? I read a math book. I study math I'm so smart ^-^

@namark It's a map? huh?
@mc nah, nothing too sophisticated, it's a matrix, with corresponding elements taken from the two vectors and added. Similar to matrix multiplication (3x1 and 1x3) expect with addition. Looking at the whole part and the fractional part of the resulting numbers separately you should see the original column and the row repeating across the matrix.
@khird I'm writing my own here https://git.qoto.org/namark/libsimple_geom
and the other usual places.
In my case this is emergent behaviour from generalizing basic vector ops to vector/matrices of any shape with support of usual c++ style arithmetic type promotion, nice to know it's a thing! This particular "fix" is not commuted yet though.
what's a column vector plus a row vector? huh? :v
huh?! :V
