I'm trying to deform a mesh but I need to use global coordinates to move the vertex. I can't just subtract the models position from the vector because the model has to be able to rotate.

You can't use a vec_rotate()?

var WorldPos[3];
var VertexPos[3];

vec_set(temp, WorldPos);
vec_sub(temp, my.x);
vec_rotate(temp, my.pan);

?


Please explain what your goal is, so we get a better idea of how to solve it...

Thanks for that, I never knew about the vec_rotate command

Let us know if it works!

And please tell us what your doing. It sounds very interesting!

I'm making a program for real time sword trails.

Its almost working now but it still doesn't work right when you rotate it around more than one axis at once
