6 years ago The RVar’s in an RDom r are accessed as “r.x”, “r.y”, or indexed on the RDom in a way I don’t immediately recall. (“r.rvar(0)”?) If the RDom is declared at class scope, the same syntax should work in both generate() and schedule().
If this is not working for you, a trivial code example would help diagnose what’s going wrong.
It is also an open question as to whether the separate schedule() method is going to be the favored way to do things. I’m a proponent for it, but it hasn’t gotten good reviews from many Halide users. Hence the disconnect in not having adequate examples.

It appears to be the case that you have to schedule rfactor or the split of an RDom Rvar in the generate() section of a Generator. If you try to do it in the schedule section, the definition of the RDom produces RVar names that are opaque to the schedule() section, even if you declare the RDom and RVars in the private area.
I looked around for an example of rfactor being used in AOT Generator style, with separate generate() and schedule() sections, and could not find one.
