What is perspective projection?

Back

Perspective projection is a way of representing three-dimensional objects on a two-dimensional surface, making them appear smaller as they get further away.

Front

What is a vanishing point?

Back

A vanishing point is a point in a perspective drawing where parallel lines seem to converge and disappear.

Front

What happens to the height of objects in perspective projection?

Back

In perspective projection, objects that are further away appear smaller than those that are closer.

Front

What is the difference between inclined and vertical picture planes?

Back

An inclined picture plane is tilted, while a vertical picture plane is straight up and down.

Front

What shape does a circle become in perspective projection?

Back

A circle becomes an ellipse in perspective projection when it is not parallel to the picture plane.

Front

What is the cone of vision?

Back

The cone of vision is the area that an observer can see, which narrows as it extends away from the observer.

Front

What does it mean when lines are perpendicular to the ground plane?

Back

It means that the lines are at a 90-degree angle to the ground, appearing straight up and down.

Front

How many vanishing points are there in a perspective drawing?

Back

There can be one, two, or more vanishing points depending on the orientation of the objects.

Front

What is the purpose of using perspective in art?

Back

Perspective helps create a sense of depth and realism in drawings and paintings.

Front

What is the effect of looking straight ahead in perspective?

Back

When looking straight ahead, the axis of the cone of vision is parallel to the ground.
