Final answer:
Texture is the term used to describe the impression of how a pictured object feels to the touch and can be conveyed both in tactile and visual forms in art.
Step-by-step explanation:
The impression of how a pictured object feels to the touch is referred to as texture. Texture may be perceived either through actual tactile sensation, such as rough or smooth surfaces in three-dimensional art, or visually in two-dimensional pieces like paintings or drawings, where it creates an illusion of how something might feel if touched. Texture adds depth and realism to artworks, as artists apply it through techniques like brushwork and layering, often aiming to replicate the sensations of different materials like rock, wood, stone, or fabric.
