The path of a moving point atthe edge of a flat shape, oroutline of a solid object. It islonger than it is wide.Lines do have some width aswell as length, this is calledmeasure.Types of line arestraight, curvy, horizontal, vertical, diagonal, zigzag, implied, and angular.
Shape is a two-dimensional areamade by connecting lines that showthe edges of an object.Shapes may be positive or negative,organic or geometric.Shapes may stand out also by adifference of value, color, or texture.
The three dimensionalprojection of a shape. It hasvolume, dimension, andappears to have mass. Thiselement is frequently used insculpture.
The appearance of lights and darksfound in a work of art.These range from black to whitewith numerous shades of gray inbetween.
The way an object or substance reacts whenlight is reflected by the object. Usuallydetermined visually by a measurement of hue(color), saturation (purity of color), andbrightness of the reflected light (how muchlight). It identifies objects, createsmoods, and affects emotions.(warm, cool, primary, secondary, intermediate, and complementary).
The roughness orsmoothness of a surface.Texture can bereal, tactile(sandpaper), orillusion (looks soft, but not).
Amount of measurable distance betweenpre-established points.Two-dimensional space has height andwidth.Three-dimensional space has height,width, volume. Deep--foreground, middleground, background. Shallow--foreground and background.
