This sketch of a book uses two vanishing points. The basic structure of the book is done in pencil with further detail being added in ink in order to give the book more realistic detail. The spine of the book is rounded off and the size of the cover in relation to the pages has been increased. The pencil lines have been left to show how the lines are used to give the impression of a three dimensional book. In order to get the proportions of the book correct an alteration was made (the first lines showing the length of the book are left) to ensure the book looked realistic.
This image was created using a single vanishing point. Detail has been added to this image by softening edges and added shading. The technical lines have been left to show the vanishing point along with the projection of the lines. A checkerboard tiled floor adds to the feeling of distance.
These two images use one vanishing point to help convey depth. The first image shows a birds eye view over structures. The image has been left unfinished to show the vanishing point and radiating lines that were used to create the image.
The second image shows a view of the structures from the ground. Both images use a single vanishing point to help create the illusion of distance and perspective.
This image was created using two vanishing points and shows a view of some buildings. Shading has been added with pencil to highlight the light source coming from the left of the page.
