We saw at the TIP 109 How to draw Cast Shadow using PARALLEL source light (such as the sun). Today let’s see more about DIVERGING source light (such as 1 or multiple projectors).
You are free to use any of these 2 techniques.
To illustrate both techniques, let’s consider the volumes in the videos to be something you could hold in your hand. Basically, I consider that the “Parallel source light” would come from a (huge) wide source of light such as the sun. The “Diverging source light” would fit better for small lights such as projectors.
Note that it’s all about scale. If you draw an entire city with high buildings, you may want to use the Diverging source light. It may give a more “dramatic” result.
At the end it’s up to you to choose the graphic impact you want to give to your sketch.

I recommend you guys to try to draw a few and test a minimum of 5 different source of lights. Take a pen and let me know how it goes in the comments below !
Note: Do not train using any ruler to trace the straight lines. It’s a good habit to take from the start. If needed, you can click here to get a tutorial on how to draw straight lines without ruler.

August 11, 2015your cylinder does my head in,I thought the light source had to be shown at a right angle to the floor but that just looks like you have drawn the light on the rail at the top, but at the front of the cylinder and then connected it to the floor at the back. 🙂
