So actually rotating the implicit is kind of difficult. An easier approach is as follows.
f(p::Primitive,x,y,z) = n
We say x,y,z
is in p
if n
< 0, on the surface if n
= 0, and outside if n
> 0.
So we leave the primitive definition at the origin. We keep a homogenous transform matrix (T
) with each object. To then test point membership we apply the inverse of T
to the point and use our origin-centered primitive.
Open questions: How to do bounding boxes? I think we will need all 8 points to do it robustly.
I am not sure how this will affect Rvachev functions.
