point inside volume

Is there a quick way to check if a point is inside a volume?

Looking at evCollision, not sure it'll work with a point. Not sure if it's even close to what I want.



In the case above, this would be true.

    I don't know if evCollision will work (it should in principle, but I haven't tested it and it's 50-50 whether it actually does).  One possibility is if q is a query for a body, then
    evaluateQuery(context, qContainsPoint(q, point)) != []
    will evaluate to true if the point is inside (or on the boundary of) the body.

    Another way is checking if evDistance between the point and the body returns a distance of zero.

    wow, thanks for quick response.

    Tried evDistance, seems to return distance to closest face inside or outside body. evDistance seems to work with faces, not bodies. Correct me if I'm wrong.

    Will try evaluateQuery.

    man you're good, thanks

    Just tested evDistance -- looks like it's computing the distance to the body boundary.  There is potential usefulness there (though only coupled with the knowledge that we're inside) -- logged a bug to figure out how to best expose it.
