… we experimented with representing an object with VOLUME on a plane.
Artists also have methods for how to represent SPACE on a plane.

Discuss together: what resources has the artist used to represent space in the picture?
CONICAL PERSPECTIVE is a system of graphic representation. It permits creating images that represent space as the human eye perceives it.
The human eye perceives objects in perspective The FARTHER AWAY an object is to us, the SMALLER it appears. The NEARER an object is to us, the BIGGER it appears.
FAR
NEAR
Conical perspective has a series of graphic elements that permit the representation of 3-dimensional space on a plane. ď‚ž These elements are planes, lines, and points. ď‚ž

The picture plane is the plane used to record the picture.

When drawing in perspective, the ground plane is the horizontal plane representing the ground on which the viewer is standing.
The horizon line is the line at which the sky and earth appear to meet. The horizon line is situated at the “eye level” of the observer.
ď‚ž
The spectator point is the position at which the spectator’s eye is located
The vanishing point is a point on the horizon line where parallel lines seem to meet in the distance. ď‚ž In conical perspective, there can be one or two vanishing points. ď‚ž

Depending on the position of the object in the picture, an artist will use either FRONTAL or OBLIQUE PERSPECTIVE.
Frontal perspective is also called “1-point perspective.” It allows us to represent an object in perspective that has a side that is parallel to the picture plane.
The front side is PARALLEL to the picture plane. 1 vanishing point is used.
Oblique perspective is also called “2point perspective”. It allows us to represent an object in perspective who’s sides are “oblique” to the picture plane (slanted, not parallel)
The sides of the objects are NOT PARALLEL to the picture plane. So, 2 Vanishing points are used
Now we will cover the steps to creating frontal and oblique perspective drawings.
We will start with FRONTAL PERSPECTIVE
Draw a simple CUBE or RECTANGULAR SOLID in FRONTAL and OBLIQUE perspectives. Put each drawing on a separate page.
Once you’ve finished, turn it into a building or another object.
