The codification of style in painting manuals like The Mustard-seed Garden and the way landscapes could be built up from simple forms has prompted modern computer programmers to simulate the small axe cut, the hemp-fibre stroke and so on. A paper by Way and Shih, for example, describes work on the synthesis of rock textures in Chinese landscape painting, aiming to provide tools for digital artists and allow the automatic rendering of Chinese-style landscapes. Their mathematical models have no connection to physical objects or natural processes; but then it is also possible to imagine Fan Kuan dabbing his brush onto the silk scroll oblivious to the rain drops falling outside. Can this gap between art and the world be closed? In his New River Watercolours, John Cage took stones from a river and drew round them to create marks not unlike roiling cloud strokes: "with the involvement of the rock, the line is not so much me as it is the rock." And Brice Marden (as I was saying a couple of weeks ago) uses sticks in his calligraphic drawing to produce natural variations in the line. These objects restrict the artist to a type of gesture whilst releasing the expressive potential of the brush stroke. Cage said that as he traced the stones, "a slight turning of the brush on my part makes a big difference in the line. So, it's hard to explain, but I'm moving toward a freedom of gesture while at the same time using gesture."
