Lecture Notes: Line, Texture, and Implied Texture in 2D Art (Project One)

The lecture opens with a quick reminder about the difference between representational and nonrepresentational art, referencing a prior Thursday discussion. If you missed that lecture, review it carefully, as understanding this distinction is foundational for the course.
The instructor emphasizes that the upcoming lectures will cover the elements and principles to be used for the project, and that while all elements and principles will be discussed, some (like balance and unity) will not be the main focus for this project.

The plan is to cover the elements and principles that will be used for the project.
Students will be exposed to slide deck content (PowerPoint) for each element, but the lectures will actively discuss how to apply them.
By the final lecture, students will have encountered all relevant elements and principles in the context of the project.

The line is introduced as one of the most basic visual elements.
Technical definition: a line is a point set in motion; the most basic case is a point, and a line can be seen as that point moving in two dimensions.
- Notation (conceptual): $L = {(x(t), y(t)) : t \in \mathbb{R}} \subset \mathbb{R}^2.$
Everyday familiarity: lines are integral to writing, drawing, and visual communication; they are not a new concept to students.
Line as a communication tool: lines convey mood and meaning without words (e.g., a thin, flowy line vs a jagged, sharp line).
- A jagged line can communicate anger or tension; a smooth, flowy line can imply calm or motion (smoke-like movement).
Line defines edges and contours: lines help define the edges of objects and form, even without color or shading (contour lines).
Line quality can convey value and impact form: by adjusting line weight, speed, and density (e.g., lines drawn quickly vs slowly, thin vs thick), an artist can imply value and shape.
Lines can be used to define edge and imply texture: lines contribute to the perception of texture and surface quality.
The discussion emphasizes that line is a foundational tool for visual communication and is encountered in everyday life (writing, drawing).

Pattern: a repeated or organized arrangement of shapes or marks.
Texture: a tactile or visual impression of surface quality; textures can be actual (tangible) or implied.
The key distinction:
- Pattern alone does not necessarily imply a tactile sensation.
- Texture implies how something would feel if touched; it can be real or implied.
Textures can be loose patterns that imply tactile sensation: a texture does not have to be mathematically precise to convey a sense of touch.
Implied texture: surface quality suggested by marks, lines, and patterns that would feel a certain way if touched, even though the surface is visually flat.
Actual texture: a surface that could be touched and would be felt (e.g., fur on a three-dimensional object).
Examples in the lecture:
- A print showing fur or hair where the texture is implied by line work and pattern rather than actual tactile texture.
- A Liechtenstein piece where the texture is implied by smeared paint; the surface appearance suggests texture without real tactile feel.
In 2D works for Project One, textures will be implied rather than actual; there may be some real texture (e.g., a rubber band pressed into paper) but the focus is on implied texture.

Implied texture relies on viewer interpretation to sense tactile qualities.
Actual texture would require physical touch or a tangible surface; in class projects, most textures will be implied to prioritize two-dimensional expression.
The level of texture can be adjusted through line work, mark-making, and pattern density to simulate different tactile sensations (e.g., sandpapery vs smooth, hair-like vs broad fur).
The example of a large swirls pattern behind a nose head demonstrates how texture is produced by paint application and line work, contributing to the impression of texture despite a flat surface.
In discussing fur and hair, the speaker notes that implied texture can convey a sense of roughness or softness even without real texture.

Swirls behind the nose/head: used to illustrate a loose pattern that has some texture due to paint application.
Liechtenstein piece: described as using smear-like marks that imply texture rather than presenting actual textured surface.
Furry cup and saucer: used to discuss implied texture and how viewers infer tactile quality from two-dimensional marks.

All textures in Project One are expected to be implied rather than actual.
An exception is a rubber band pressed into paper, which may create a real (tangible) texture if applied with enough pressure.
Students should consider how marks (lines, curves, densities) imply texture and how that implication contributes to the viewer’s sense of touch and material quality.
The emphasis is on applying the concept of implied texture to create convincing surfaces and surfaces’ qualities within a 2D medium.

Line and texture are foundational tools for visual communication, used in everyday life (writing, drawing, signage) and professional art.
Understanding line quality, edge definition, and texture implication helps convey mood, movement, weight, and materiality without relying on color or shading.
The discussion links to broader elements and principles of design (e.g., edges, contour, value, form) and lays groundwork for recognizing how these tools interact in more complex works.
Real-world relevance includes interpreting artwork in museums, galleries, and media where texture is implied through technique rather than physically present.

Implied texture invites viewer participation: interpretation becomes part of the artwork’s meaning, which has ethical considerations regarding authorial intent and viewer perception.
The balance between realism (accurate texture) and expression (implied texture) reflects broader artistic choices about truth to material and personal style.
In education, emphasizing implied texture for 2D works supports accessibility (fewer materials required) while still conveying convincing surface qualities.

Line: a point moving in a plane; visual element that defines edges, contours, and can convey mood through quality and density.
Contour line: defines the edge of an object.
Texture vs Pattern:
- Pattern = repetition of shapes or marks.
- Texture = tactile quality; can be actual or implied.
Implied texture: surface quality suggested by marks that would feel a certain way if touched.
Actual texture: surface quality that is physically touchable.
Mathematical representation of a line in 2D: L = {(x(t), y(t)) : t \in \mathbb{R}} \subset \mathbb{R}^2. $Also, a straight-line equation can be written as$ y = mx + b.$$

Review the difference between representational and nonrepresentational art.
Practice using different line qualities to communicate mood and edge definition in small sketches.
Create a study sheet linking line quality to perceived value and form.
Experiment with implied texture in a 2D piece (e.g., mark-making that suggests fur, fabric, or smooth surfaces) and note how you convey tactile sense without actual texture.
Prepare a short critique focusing on whether the texture in your work is implied or actual, and justify your design decisions in terms of mood, edge definition, and form.
