Hi. I'm working on a model exporter for blender with python. I really wanna make my own and atm i'm working with armatures(bones)
And now I realised that I need to know alot more about how matrices work.
For example I can get the "bonespace" and I don't know what that means. And the bone space is:
1 0 0
0 0 1
0 -1 0
a 3x3 matrix.
But what does all these numbers stand for? is it vectors?
there's something tkey call armaturespace too:
1 0 0 0
0 0 1 0
0 -1 0 0
0 0 0 1
a 4x4 matrix.
If you know anything about matrices and want to help me I love you!
Sorry for typos.
so no one know anything about matrices?
Well, you can use matrices for a lot of things. Equation solving, vectors, and more. As these are specific to Blender, I guess you should go see the documentation.
Aha so it's up to blender what the (rows? columns?) stand for?
Could be... But it usually has something to do with triangles and vectors.
All known model extensions uses triangles for model visualization. Then it's up to the model viewer (Blender) to show the correct model.
I actually have no idea what the matrix4 is used for. Probably alpha and colors.
lol.
matrices are used to encode transformations efficiently, basically. (in this case anyway).

Heh. I've always used it for models. Didn't know that.
thank you blankthemuffin for that link, I will read it now
