You’ll use these to select predefined colors.įinally, there are two image views called MainImageView and TempImageView - you’ll see later why you need two image views when you use them to allow users to draw with different brush opacity levels. On the bottom, you can see more buttons with pencil images and an eraser. As the titles suggest, you will use these to reset or share a drawing and to bring up a Settings screen. The initial ViewController scene has three buttons on the top. Open Main.storyboard and look at the interface.
The whole project is based on the Single View Application template. You have all the needed images in the asset catalog and the main view of the app with all needed constraints set. As you can see, not much work has been done for you. Start Xcode, open the starter project and have a look at the files inside.

Use the Download Materials button at the top or bottom of this tutorial to download the starter project. Grab your pencils and get started no need to make this introduction too drawn out! :] Getting Started

Want to learn how to make a drawing app of your own? The good news is that it’s pretty easy, thanks to some great drawing APIs available through UIKit in iOS. Abdul Azeem Khan wrote the original and Jean-Pierre Distler completed a previous update.Īt some stage in our lives, we all enjoyed drawing pictures, cartoons and other stuff.įor me, it was using a pen and paper but, these days, the old pen and paper have been replaced by computers and mobile devices! Drawing can be especially fun on touch-based devices, as you can see by the abundance of drawing apps on the App Store. This has 2 vanishing points on the horizon and the rule is:Īll lines that are not vertical go to one or other of the vanishing points depending on which side of the object they are on.Update note: Ron Kliffer updated this tutorial for Xcode 10, Swift 4.2 and iOS 12. In single point perspective all lines that are not horizontal or vertical go back to that vanishing point. Draw a horizontal line on the paper where you want the horizon to be.and mark a point on it for reference. We see lines that are really parallel (railway lines for example) as converging to meet at a point on that horizon called the vanishing point, (a trick of the eye/brain) but we can use this to make drawings look more realistic. When we look into the distance we perceive the horizon as being at our eye level, so lower when sitting than when standing. Is basically simple but practically gets complicated with bigger drawings so I direct you to the Wiki article In both oblique projection and orthographic projection, parallel lines of the source object produce parallel lines in the projected image. It projects an image by intersecting parallel rays (projectors)įrom the three-dimensional source object with the drawing surface (projection plan). One of the things that makes isometric drawings so attractive is the ease with which 60 degree angles can be constructed with only a compass and straightedge.Īn oblique projection is a simple type of graphical projection used for producing pictorial, two-dimensional images of three-dimensional objects: "Isometric" comes from the Greek for "same measure".
Isometric projection corresponds to rotation of the object by ± 45° about the vertical axis, followed by rotation of approximately ± 35.264° about the horizontal axis starting from an orthographic projection view. The isometric projection show the object from angles in which the scales along each axis of the object are equal. All of which have their place, but are not essential skills (at first) There are a number of drawing formats, Isometric, Oblique, Single point perspective, 2 point perspective, 3 point perspective. This wiki article puts much more flesh on the bones of formal drawing rules Third angle projection is primarily used in the United States and Canada, where it is the default projection system according to British Standard BS 8888 and ASME standard ASME Y14.3M, the left view is placed on the left and the top view on the top. The 3D object is projected into 2D "paper" space as if you were looking at an X-ray of the object: the top view is under the front view, the right view is at the left of the front view.

(of course).įirst angle projection is the ISO standard and is primarily used in Europe. There are 2 standards in the world The USA and most of Europe. Tto supply this there are some rules you can follow that will in general be understood by any engineer trained to read format engineering drawings.ġ. To get the idea of an object from a side, front and top view you need some frame of reference.
