Cross Contour Lines

This video tutorial introduces the concept of cross contour lines, explaining their role in transforming two-dimensional shapes into three-dimensional forms. It covers how cross contour lines can indicate the orientation and position of objects in space, and how they can be applied to various shapes to provide depth and volume. The tutorial also touches on the principle of linear perspective, showing how cross contour lines get closer together as they move away from the viewer. The session concludes with a preview of more complex applications in future lessons.

What is the primary purpose of using cross contour lines in drawing?

• To add color to the drawing

• To create a three-dimensional effect on a two-dimensional shape

• To outline the shape

• To erase mistakes

How can cross contour lines indicate the direction an object is facing?

• By changing the color of the lines

• By altering the thickness of the lines

• By adjusting the position and curvature of the lines

• By adding more lines

In the context of cross contour lines, what does curving the lines over the top of an object help determine?

• The color of the object

• The texture of the object

• The size of the object

• The position of the object in space

What additional information can cross contour lines provide when applied to organic shapes?

• The color of the shape

• The depth, volume, and direction of the shape

• The size of the shape

• The texture of the shape

What is the effect of adding more cross contour lines to a shape?

• It erases the shape

• It defines the shape more clearly

• It adds more color to the shape

• It makes the shape less visible

What happens to cross contour lines as they move away from the viewer?

• They disappear

• They become thicker

• They change color

• They get closer together

Why do cross contour lines get closer together as they move away from the viewer?

• Because of the lighting

• Because of the texture of the surface

• Because of the color contrast

• Because of the principle of linear perspective
