This document discusses different visual elements including the dot, line, plane, and texture. It describes the dot as the smallest visual element that can be a geometric point or have size, color, and texture as a graphic dot. Lines are defined by their length, color, thickness and edges. Planes are two-dimensional surfaces that can provide an illusion of three-dimensional space through techniques like overlap and shading. Texture refers to the appearance of a surface and can be tactile, graphic, natural or artificial; textures can be smooth, rough, grainy and affect the look and feel of an artwork. Lighting is also discussed as an important factor in how textures are perceived.
