Perspective | How to visualize and spot the converging lines? | TIP106 | VIDEO

When you sketch an object, most of the time you can’t possibly draw the full set of Perspective:

  • Horizon line
  • Vanishing points
  • Converging lines.

However, it’s SUPER ESSENTIAL to always keep in mind the perspective rules to make sure that your sketch is correct.

With practice, your brain will end visualising the converging lines intuitively. Make sure to train your perspective skills drawing many simple shapes such as cubes from different views. 

VERY IMPORTANT:  the converging lines are one of your Best friend !!
The lines looks parallel, but they are not. They slightly diverge. If one day, your sketch looks “awkward”, and you wonder why ? Check your converging lines. It will solve a lot of mistakes. Without them, you can’t possibly imagine to draw in “3D” from your imagination. So, each time you get to practice, visualise them or draw them with a light pressure with your pen.

Hint: as we can see the top of the razor head, it means the razor is below the Horizon line (also called the Eye level).

I did this sketch with the software Sketchbook Pro, with a Cintiq 22HD. If you also love sketching on tablet, I warmly recommend you guys to download that awesome and light drawing software (Free trial). Product and transport designers love it! The lines looks natural.

If the sketching methods I’ve acquired aid me in my life and in my career, I believe that they can also help you to learn, and help you with your projects. Whether Design is a job or a hobby it doesn’t matter, so long as you do what is important to you.

    Thanks, I was wondering how do create the converging lines for vanishing points that are off the paper?

      Always keep in my mind the converging lines, even though they are very far. Some people like to exagerate the angle of these lines, getting closer to a fisheye effect. Why ? To make the sketch more impressive. It’s a pretty common technique for transport designers.
