2 point perspective

This page will include introduction of different 3D sketching techniques and some close up looks on 2 point perspective work.

Methods of 3D sketching

There are several different ways to present a design with 3D sketching.

Isometric sketching

Isometric sketching is a drawing of three dimensional shape along a vertical line with at least two identified points. The picture on the left shows the basic rules of isometric sketching, with 30 degrees to the side and 120 degrees on the top.

1 point perspective

This sketching method involves one vanishing point on the horizon line. The shapes gets smaller as they go towards the vanishing point.

2 point perspective

This is the sketching method I will be using. This method involves 2 vanishing points on the horizon line. This method have several perspectives of the shapes; the one where I can see the bottom, the one that only shows the side, and the one where I can see the top. In design and technology, we often use the low perspective with the top visible as most of the object we see in daily life is on the table or below us.

I started 2 point perspective sketching with page 1. In this page, I have drawn 12 different boxes below, on, and above the horizon line to experiment with angles.

These are the tools I used; a ruler and a blue pencil. Ruler can be used to draw the straight line from the vanishing point to a place where I want the shape to be.

First I drew the horizon line and the two vanishing points

Then I drew two straight connecting lines from the vanishing points

And drew the straight vertical lines and connect does to the vanishing points in straight line.

This is the finished 3D shape using 2 point perspective sketching method. I drew total of 12 boxes on this page as a practice and experiment of the 2 point perspective drawing.

For the next page, not only sketching the 12 boxes, I also sketched some designs and fine lined it like an actual design ideas. These sketches will only be under the horizon lines as most of the object we see daily are below our eye level. For each boxes, different horizon lines will be drawn.

Once I have finished sketching, I then fine lined it with thick and thin line method, with 0.8 and 0.3 fine lining pens and ruler if necessary.

Procreate : textures

Now, I will render boxes with 2 point perspective method in procreate. Additionally, I will also add textures and shadows for more realistic and 3D like presentation of my designs.

I first started with turning the 'drawing guide' on. This provides me to set the drawing guide as I want - this case with 2 vanishing points.

*note that the horizon line is outside of the page (up) for all shapes to be under the horizon line.

This is how the page looks like with the drawing guide on. There's a useful tool in procreate - 'drawing assist' which only lets me to straight lines towards the vanishing points. This makes drawing in procreate much more effective as it reduces the time of using rulers and matching the corners of each lines when drawing a box.

This is how the blue pencil sketching looks like on Procreate with drawing assist & drawing guide. Much faster and easier!

Now to fine lining, I used Technical Pen in Procreate with the thickness of 4% for thin lines and 6% for thick lines. I drew the thin lines first to make masking the textures easier later on.
