We can put pictures into this space which is created by starting an uninitialized computer.
But, we are accustomed to thinking about an image as an abstraction, for the purpose of putting it into a computer. We can ask contemporary computers to show us an image of the folder in which an image has been stored, and in that image we will be able to see the file. We will see its name, written out in letters and numbers.
We can open that file in some kind of program window, and that window will show us, on the screen, a representation of the bits in that file ... 01100000000001 ... Each bit is represented by a small image, and those images are arranged on a line, creating a composite image which is a representation of the data in that file.
We can open the file with some kind of image viewer - we can ask our computers to do that - and then we will see ... the picture. The image. The image the data in that file intends to represents. It will be composed of a large number of colored squares, in an array, on a surface. The surface is a plane, and each of the colored squares is a segment of and on that plane, as is the entire picture.
It is impossible to see data on screen without drawing pictures ... on the screen. And it is impossible to see things in space that are not surfaces. This is true in reality, as it is in virtual reality.
Computer, draw me a floor. Call it my floor. Place one of its corners five feet below my viewing point, and make it a rectangle 600 feet deep and 400 feet wide and perpendicular to the camera standard. Also, the edges are either parallel to or perpendicular to the screen plane. Color it light grey.
Computer, on my floor, whose zero point is five feet below the view point, locate the point 100 100 in feet. Now locate a point 3.5 feet directly above that point. Let the left edge be a line segment forward 8 feet, and let the front edge be a line segment to the right 20 feet, and let these two edges define a rectangle. Call this rectangle my table and color it pink.
We call the above procedure laying a generic rectangle on a rectangle. Laying a generic rectangle on a rectangle is a member of the class of actions called laying a rectangle on a rectangle, which is a member of the class of actions called alignment. To lay a generic rectangle on a rectangle we identify a rectangle to lay it on, a point above which to locate its origin, 1 foot 1 foot, the specify that the origin be .01 feet above that point, make its left edge 4 feet long, its front edge 3 feet long, and color it white. Notes. The rectangle to be aligned takes its directions from the direction defining axes of the the rectangle with which it is to be aligned, front edge and left edge.
Call the new rectangle my page.
Finally, Computer, please center a 3 foot wide image of the Google home page, http://www.google.com, on my page is the center an image on a page instruction.
