Two-Dimensional
Optical Texture
Texture can be both tactile and optical. The tactile kind
is associated with descriptions such as rough, smooth,
bumpy, ridged, gritty, creased, crumpled, and silky. It
responds to your sense of touch. Optical te xture can be
detected only by your sense of sight. Areas of a painting
may appear to have three-dimensional texture, whereas
really they are smooth to the touch. Imagine a photograph
of a field of stubble. Experience tells us that the stubble
is rough to the touch. But if you run your fingers over the
photograph, it will feel smooth.
