The only parametric "modelling" I've seen done, and have done, using textures is using the height map on a suitably tesellated mesh. You can get clever and complex with it but it doesn't have the full flexibility of an object graph to extend the mesh itself.
Sorry，maybe I wasn't clear enough，what I mean is imitating the parametric modeling，texture could accomplish more meta texture append or reduce through change parameters. Like the node splatter_circular，change the parameters，and texture appended or reduced.
what I want…… like this picture. Once the edge change then the triangle and circle append.
