12/18/2023 0 Comments Gridded pictures to draw![]() ** Further there is a general BUG in all, but some very special experimental, vector graphics drawing engines. trimming efficiently requires 400-1000 more lines, and me to know a lot about a lot. I can make a snapping line drawing tool in 20 lines of javascript. * Trim requires more complex data structures and is generally nasty to make efficient in the software whereas just drawing shapes as you encounter them is built into the hardware. Or just do it in autocad extort to PDF and open in illustrator if you feel learning something is beneath you. It is painful to understand that what you take for granted isn't so self evident. Unfortunately you may need to learn your workflow from scratch. Though that may be a white lie, its easier to make faces than delete just lines, id have to click around and dragging lines is faster in this case. Now, I have created faces because I may want to color the surfaces later (see image 2). Image 1: How a illustrator user would approach your first image. But face priority becomes a boon when you realize you can color the areas between lines, in which case they need to be faces anyway.** That's what most users are doing after all. It is however primed to make faces by default. Now the equivalent of trim in illustrator is shape builder. In 2d graphics land trim is a really advanced feature almost unheard of.* Now unfortunately to you the simpler the software gets the less likely it is to understand this, and force the world view. Often users on both camps lack the understanding that you can in fact use both in both cases and that ultimately it depends on you level of abstraction as to which you will choose. Graphic software users think that the face is the base primitive.CAD users think that the line is the base primitive.Before you embark on this road it may be good to know that there is a fundamental world view difference between graphic software users and CAD users. Internalizing is different from intellectual understanding.Ok. It's like the difference between reading The Lean Startup and spending two years of your life failing at a startup because you weren't agile enough. I've always had an intellectual understanding of "losing the forest for the trees", but something about last night really hit home and helped me internalize it. It honestly felt like a very powerful moment, and I'd recommend that you go through the grid drawing exercise and try to reproduce that moment yourself. I just kinda moved from square-to-square without factoring in the adjacent squares too much.Īnd that's when it hit me that this is exactly what it means to lose sight of the forest for the trees. ![]() But if my version of the adjacent square, E20, is screwed up, I should factor that in to my E21 square. Say that in cell E21 the line in the reference image starts about 25% down from the top and goes at an angle of about 45°. Reductionism is a thing, right?Īnd then I realized: small errors in each individual square can compound and make the zoomed-out version look terrible.Īnd furthermore, I was paying too much attention to the individual squares and not enough attention to the zoomed-out version. ![]() the zoomed-out perspective still looked like garbage! Maybe I screwed one of them up or something. Huh? How could that be? So I went through each of the squares I drew and compared them to the ones in the reference image. But then I zoomed out and looked at what I had. I was going square-by-square, and I felt like each individual square I drew was pretty close to the one in the reference image. But then once I moved on to a harder image, I ran into a weird problem. I was successfully using the technique to draw easy things. I think the idea is that there's less going on inside an individual square than there is when you zoom out and look at the image as a whole, so by approaching it this way it ends up being easier for the artist.Īt first this felt like it made a ton of sense. So on and so forth until we have gone through every square. ![]() Then we move on to A5 and do the same thing. We look at what A6 looks like in the reference image and try to copy it into our version of A6. For the flower, maybe we start at square A6. Then you go square-by-square and try to copy what you see.įor example, let's say that rows are labeled A through H and columns are labeled 1 through 11. Then you draw grid lines on your version. You draw grid lines in the reference image. The top image is the reference image, the bottom is your version. To start, let's back up and talk about what grid drawings are. In doing so, I ended up having a lightbulb moment where I really internalized what it means to lose the forest for the trees. Last night I learned about grid drawings and spent some time trying to work on them.
