sai sometimes just goes all wonky and i can't do things

anonymous asked:

Hi, i'm sorry if i'm bothering but i'm making my portfolio for applying to an animation school and it's supposed to be finished in february and i just can't seem to get perspective down properly and i was wondering if you have any tips since your art is so good and you already attend an animation school? Any tips or guidelines would help. Thank you. (And if you're busy i'm sorry and i hope you have a nice day and start feeling better soon becaude i know you've been depressed for a while, sorry)

Oh gosh its no problem at all!! I hope the portfolio goes well for you!! Also thank you very much for the kind words, I’ve been on the up recently and I hope to keep getting better ; v ;!!

As for tips, one of the most important things to do (at least when I do it) is go for the feel first and sketch it out without rulers. Try to see how the form looks with just your eye, maybe try sketching out lots of simple objects first (like shoe boxes or tables) from life to improve your observation skills. Then, go back in and fix the perspective with rulers and horizon lines (shortened to HL for my sake haha) and vanishing points (VPs). 

The thing about all the rules about rulers and HLs and VPs is, they’re there to polish up your work and make the ideas you already have more accurate to life. If you go straight into constructing forms using HLs, VPs, and rulers, its going to feel stiff and awkward, and the forms won’t have quite the right proportions etc. It’s hard to see the big picture when you’re already caught up in following all the rules of proper perspective. If you flesh out your scene first with your own ideas and fix it up later with rulers, it’ll strengthen the work. 

Here’s a tutorial of what I mean: 

Say I want to draw a desk! In order to do that, I first draw the sketch of a desk. This is purely from my knowledge of shapes and forms, and isn’t entirely accurate. That’s okay tho! We’ll fix it later.

Once you’re satisfied with your sketch, pull out a ruler! Pick two lines parallel on your desk that you like the angle of, and extend their lines until they join up. That’s your first VP! 

Since this is a two point perspective object though, we need a second VP for the perpendicular lines. In order to do that, we need to create a horizon line. 

A horizon line in two point perspective will always do two things: 1, connect with all of the VPs, and 2, be perpendicular to all 90* verticals (for example, the table legs). With these two rules in mind, draw a line extending from the first VP perpendicular to the table legs. Now you have a horizon line! This is where the eye level of the viewer is. 

From there, take one of the tabletop’s perpendicular lines and extend it until it reaches the horizon line. This creates your second VP. 

Now comes all the corrections! Using your two vanishing points, connect all the parallel lines to their respective VPs. I usually line up the point furthest on the line to the VP, and let the VP correct the rest of the line. For things like table legs, the bottoms of them lie flat on the floor, so treat that like it’s one line. 

Once you’ve corrected all your lines, go ahead and draw in the form! If you aren’t confident in your lines or want a really straight edge, go ahead and use a ruler. Otherwise I tend to sometimes wing it for a more natural aesthetic, but it’s not everyone’s taste.

And there you have it, a more accurate table! Go ahead and erase any unwanted lines and you should be good to go :) 

Keep in mind this works for whole scenes at a time! As long as you have appropriate VPs and stick to them, it will clean up and fix your issues really well. 

Just be sure to keep in mind, the closer the vanishing points are to each other, the shorter the focal length. That means it will look more dynamic, or potentially wonky if they’re too close together. Further apart vanishing points means longer focal length, meaning flatter images (which can be good if you want something to look dull and boring). 

I hope this helps! If you have any more questions just ask! :)
