When working on GLSL you format and edit matrices constantly. Matrices can be hard to read and edit which leads to mistakes. We created a little tool to make it easier.

GLSL is hard enough to debug as is, so knowing that you’re putting your 0’s and 1’s in the right place is a lot of help.

Check this out. Try to change the 0 to a 1 in the third row, second column.

[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]

You’ll be counting and fumbling to find the right row or column.

Can’t get it? It’s here.

[0,0,0,0,0,0,0,0,0, -> 1 <- ,0,0,0,0,0,0,0]

UGH! It’s a needle in a haystack!
