Artical About Gravel Grids

The Ground Base Grid can be used to plot all of the points in the vista seen through that loop. After that, those points can be transferred to the grid-inscribed paper on the right table. Therefore, the steeple can be plotted at B3 on the paper if it is located at B3 in the grid frame.

 When an artist wants to paint a scene at "sight size," the painting or drawing is exactly like the image on a piece of glass that is perpendicular to the line of sight. You could see a scene through a window and see the main lines directly on the glass if you could keep your head still and look through only one eye. A drawing that perfectly reflects the observed scene would then be created by drawing those lines on paper.

Albrecht Durer, a Renaissance artist, made the idea better. The artist appears to be drawing lines on a piece of glass propped up in front of the seated model, as the vertical post holds the artist in place. Durer draws another setup in 1525. He is this time looking at the lady through the grid of black threads rather than drawing on the frame, and he is then transferring that image onto the corresponding gridded piece of paper that is laying flat on the table in front of him.

In his book "On Painting," Leon Battista Alberti shows a vertically arranged wooden frame in front of a city scene. A Gravel Grids of black threads is stretched across the frame. A loop at the top of a vertical post indicates the viewer's position. This apparatus has been referred to as an "Alberti's veil," a "drawing grid," a "perspective grid," or a "draughtsman's net."

If the goal was to rearrange, caricature, or stylize the subject, a tool like this would not be very helpful. However, if the objective is to accurately capture a scene, it eliminates a lot of guesswork and error and would be particularly useful for foreshortened figures, oblique perspectives, and curving objects like cars.

A drawing lattice is a basic, direct, and clear approach to catching the primary lines of a scene precisely as an underlying move toward the interaction. It's similar to drawing a scene using a set of slopes and segments while holding your pencil at arm's length. However, the grid method is significantly more effective and accurate than the "outstretched-arm-holding-a-pencil" procedure due to the fact that it immediately produces a complete image as opposed to a collection of measured segments and slopes that need to be assembled and corrected one at a time.
