Which of the following enhances a perspective drawing by adding realism?

Texture enhances a perspective drawing by adding a tactile quality that conveys realism. When textures are applied to surfaces in a drawing, they provide visual cues that simulate the physical properties of materials, such as roughness, smoothness, or the way light interacts with different surfaces. This detail allows the viewer to better understand the materials depicted, contributing to a more lifelike representation.

In contrast, while lighting effects can create a sense of depth and atmosphere, they primarily affect the overall ambiance rather than the material quality. Patterns can add visual interest, but they often do not communicate the unique characteristics of the surfaces. Dimensions, while essential for understanding the scale of elements in a drawing, do not directly contribute to the realistic representation of materials. Together, these concepts may complement texture, but texture is the primary choice for enhancing realism in a perspective drawing.
