Sculptural and spatial practice for me has always been more expansive than Kraussian quadrants. Simply; sculptural and spatial practice encompasses a wide range of philosophical and artistic interrogations that break down/emphasise/piece together how humans perceive and feel dimension and expressions of form* that can include, painting, drawing, photography etc.
British artist and painter Clare Woods is a great example of an artist working in a medium traditionally considered outside sculpture, but whose practice is formally sculptural. Woods uses paint as a means of expressing the three-dimensional value of form using techniques that emphasise the structure of an image (see below video).
I think it’s important to recognise that historical as well as contemporary sculptural and spatial practice is consistently an expression of form relative to human and human-scale concepts of space and time. As such, form is perceived and experienced at a human level as both a 2D as well as 3D phenomenon relative to distance/proximity. I can’t help but wonder why, at least in Australia, formal distinctions that individuate sculpture from drawing from printmaking from photography etc. continue to persist despite contemporary social shifts in understanding about dimension/space-time concurrently with acknowledgement of the advent of the Anthropocene.
NB. I consider that there is a distinction between the philosophical and artistic interrogation of the dimension and expression of form (sculpture and spatial practical) and the rendering/depiction of form to create the illusion of dimension (broadly printmaking, drawing and painting).
