Quick sketch: notions of perspective, orthogonal projections and 5 drawing techniques

Most people who don't draw haven't had the chance to learn a technique that allows them to construct a drawing. Knowing how to draw is no different from following a recipe for cake. Without a recipe, there's little chance of success.In this book, five drawing techniques will be explained to you, enabling you to achieve the basics of any perspective sketch.Where is the horizon line? It's the first thing you need to know before you start drawing. Understanding the horizon line and how it influences the drawing is the introduction to my book. The observer, his point of view, the height of his eyes and his angle of vision are also important concepts in this part.Every object has a different shape, and reproducing it in a sketch can seem arduous. However, each object fits into a cubic volume. Frontal perspective (1 vanishing point) and oblique perspective (2 vanishing points) are not presented in the traditional way, with disarming geometric rigor. My techniques offer a great deal of flexibility and greatly speed up the drawing process. Finally, the refinement of the drawing through light and shadow enhances the sketch. A picture is worth a thousand words, and a quick sketch allows you to quickly visualize your ideas. The aim of a sketch is not to make a beautiful drawing, but to quickly produce an idea in perspective. Your creative medium will become the placemat in the restaurant or the sheet of gypsum on a construction site. The quick sketch is not an end in itself in the creative process; it allows the designer to explore a fascinating three-dimensional universe to validate a variety of ideas. Gone are the days of straight lines drawn with a ruler - it's time for the quick sketch!
