How to use VEX coding to achieve the same result as transform function in primitive sop node

[asxp3]

The question is same as the title shows, I tried serval ways in vex, but all fail, so I'm so curious that how to make that happen in vex?

Anyone knows?

You can use maketransform(): http://www.sidefx.com/docs/houdini/vex/functions/maketransform

Put this in a pointwrangle and make sure to set all scale values to 1.

int trs  = chi('transformation_order');
int xyz  = chi('rotation_order');
vector t = chv('translation');
vector r = chv('rotation');
vector s = chv('scale');
vector p = chv('pivot');

matrix m = maketransform(trs, xyz, t, r, s, p);
@P *= m;

Thanks konstantin Magnus! This is something I was searching for:-)
