Identify and describe two ways to express three-dimensional attributes in two-dimensional work.

Three
ways to create three-dimensional effects are shading, anaglyph, and perspective.

Shading is applied to a drawing of an object or figure to make it seem that it is
lighted from a particular direction and casting a shadow.

Anaglyph refers to
the addition of colors, usually red and cyan, to create a stereoscopic effect. The colors are
encoded separately for each eye, and the optical combination with both eyes creates the 3D
impression (with special glasses).

Linear perspective is used in drawing a
scene. It may be one-point or two-point perspective. Linear refers to drawing a line to a point
that draws the eye toward it, creating the appearance of depth. One-point perspective guides the
eye to a single vanishing point where two lines meet. Two-point employs two vanishing points,
usually at opposite sides of the composition.
