Sacrifice of Isaac, created by Andrea Mantegna, is a great example of foreshortening. Forshortening is "the dimentions of the closer extremities that are adjusted in order to make up for the distortion created by the point of view." You see the acceptance in "Isaac's" face, and the noble expression in the mans eyes, when he's looking at the hand coming out of the wall. It's a very distorted painting, and represents the the functions of three-dimensional objects.
Oblique Projection is a simple type of graphical projection used for producing pictoral, two-dimensional, or three-dimensional images. Mandala of Kuman Shrine, is what the painting to the left is called. It was created by, Kumano Mandala, and is a great example of oblique projection. The painting has a parallel sides of the object, and one face is parrallel to the picture plane as well.
Positive Space is defined as, space that is occupied by an element or form. The picture to left is called, The Charm of Substance, it is created by Martin Puryear. The form in the picture is the positve space. not the area around it, but the form itself. This form helps us recognise the impotance of the differences between positive and negative space. Negative Space is defines as, the space around and between the subject(s) of an image. In this case its the painted wall behind it, and also the area in which the form is sitting on.
Line Oreintation of Composition- Horizontial/Vertical is defined as, expressive qualities that are closely associated with their oreintation in the composition. They emphasize the horizontal and vertical process a certain architectual stability, that mathmatical, rational control. The picture to the left is called, Leonidas at Thermopylae, created by Jacques -Louis David. Althought the picture is too faint to see, the arrows are pointing to verical, and horizontal lines that indicated a grid that is mathmatical. All the figures are perfectly lined within the painting, which shows skill, and patience throughout.
Implied Line, defiened as, a line in an artwork that is not physically there but suggested by points in the artwork. Madonna and Child, the name of the artwork to the left, created by Titian, indicated that the implied line is the where the mother is looking down at her child, and the child is looking down to it's right. You can't see the line where the eye sight is going from both the mother, and child, but you figure its there because of the way the eyes are directing their sight.
Outline is a shape that can be indicated by an edge of a two-dimensional (flat) shape or a three-dimensional form. In the picture to the left, the Mummy Head, created by Henri Gaudier-Brzeska, represents how it doesnt need much detail to the drawing. The outline itself can be quite detailed. The thickness of the lines where the head is, and the thinness of the lines where the mouth and part of the eye shows how the outline can be expressed in many different forms.
