What is the feature of cross contour drawing?

Cross contour drawing is characterized by the use of lines that traverse the surface of the form to indicate changes in volume and three-dimensionality. Unlike simple contour drawing, which only outlines the edges of an object, cross contour lines follow the shape of the object and illustrate its dimensionality by changing direction and spacing along the surface. This technique helps to convey the form and volume of an object, giving it a more realistic appearance on a flat surface.

The other options do not accurately describe cross contour drawing. For instance, focusing exclusively on color application relates to color theory and painting techniques, while cross contour drawing primarily emphasizes line work and form. Similarly, stating that it is limited to two-dimensional representations does not align with its intention to depict three-dimensional qualities. Lastly, the requirement of digital tools does not apply to cross contour drawing, which can be executed in traditional mediums such as pencil, ink, or charcoal.
