I have to write a paper comparing two art sculptures.

I have write if it's an open or closed contour but I don't know what that means.

closed contour: like a solid, enclosed mass: soccer ball, or a cube

Open contour; the inside is revealed: like a cutaway, or a klein bottle (Broken Link Removed)

To determine if a sculpture has an open or closed contour, you need to understand the concept of contour lines in art. Contour lines are the continuous lines that define the edges and boundaries of a form or shape in a two-dimensional artwork.

An open contour is when a line does not complete a shape or form, leaving it open-ended. It means the line does not enclose or connect to itself, and the shape or form does not have a distinct beginning or endpoint. Examples of open contours in sculptures could be an incomplete circular shape or a line that stops abruptly without closing itself off.

On the other hand, a closed contour is when a line completes a shape or form, creating an enclosed area. The line connects to itself, forming a complete loop or shape with a distinct beginning and endpoint. An example of a closed contour in a sculpture could be a circular or triangular shape where the outline connects seamlessly.

To determine if a sculpture has an open or closed contour, examine its overall shape and the lines that define its edges. Look for any gaps or breaks in the lines that would indicate an open contour, or observe if the lines form a complete loop or shape indicating a closed contour.

By analyzing the contours of both art sculptures you are comparing, you can identify if they have open or closed contours, and use this information to write your paper.
