Hi,

How can I obtain point’s coordinates in a specific coordinate system ?

It seems pretty simple but I can’t find the node to do that.

Thank you

Thank you Alban,

This is not what I’m searching for.

I’m looking for a mathematical conversion of the point P coordinates from the general coordinate system (O, x, y, z) to any other coordinate system (A, i, j, k).

Thank you for this proposal. It’s close to what I’m looking for. But your solution works only if coordinate systems are parallel. I’m searching for the general solution.

I was expecting to find something already existing. I will try to code the node, if I can remember my math…

Ok, I made a custom node to do it.

If someone wants to convert it in python to make it faster, feel free … I will probably do it soon or later, but probably later…
