Hi there, Yes perspective can be challenging to learn, but don’t worry you’re on the right track. The main reason your 2nd and 3rd cylinders look off is because you’ve not actually drawn a cylinder. Instead you’ve drawn a rectangular box rather than a square box and that’s why they don’t look right. Remember that the basic shape of a cylinder is a circle, but when viewed from an angle it appears elliptical. To draw the ellipse in perspective you need to keep in mind three things. The first is the minor axis which runs down the length of the cylinder and will point towards the vanishing point. Next is the major axis which is always perpendicular to the minor axis regardless of perspective. Lastly, the ellipse is always divided evenly into 4 hemispheres around the major and minor axis. So the only thing left for you to determine is how much of the minor axis you will see. If you’re looking at the cylinder front on it will be a circle (therefore the same length as the major axis) and it will get shorter and shorter until you’re looking at the cylinder from the side where you won’t see the ellipse. In a 1 point perspective, only the Z axis is converging. So cylinders drawn like #1 will always appear as a circle. For #2 and #3 the vanishing point for the minor axis is so far off the page that it is assumed to not exist. That means the major and minor axis will always be vertical or parallel to the horizon depending on the orientation of the cylinder. It’s not until you start using 2 or 3 point perspective that that changes. On a more practical note, while it’s good to know and understand the theory, try to develop your intuition rather than relying on rules and formulas. Your cylinders don’t have to be perfect. The important points are understanding how to orientate the ellipse based on the three things I mentioned. As you progress you will start to manipulate the cylinders, so you won’t be drawing perfectly round cylinders anyway. Hope that makes sense, please let me know if you have any questions. | Artwod Feedback
