I don't think this would be any different from having multiple blob
objects with some identical components. And I don't understand your
reasoning in calling it a "threshold identifier", since it doesn't seem
to have anything to do with the threshold...a possible sign that I
completely misunderstood what you were trying to say. :-(
And anyway, you still have the problem of determining which set of blob
components to use. The components are not blobbed together one by one
and the results rendered, their contributions to a point are added
together and the equation solved for each ray. How do you decide which
components to use in the solving process when you have a ray, or even a
point, as the starting information?
The only way I can see something like this being possible is by making a
new type of blobby object which takes components that are turned into a
mesh, and blobbed together one by one in a tree structure. Then the mesh
object would be rendered...of course, this has all the problems of
tesselating into triangles(probably even harder because of the specific
order the components would be combined in).
