How to design a Cathedral

cathedral design dark black


For the basic shape of this building I drew a large number of simple 2D forms. I made variations and I corrected the forms until I was happy with one form.

What did I do next? I looked for different ways to transform this simple 2D form into a full 3D object. I also added colours and I drew the lines for the windows. One important thing I noticed is that adding colours in the earliest stages of design is crucial for a good end result.

Colours have a strong influence on the composition and the way the different shapes interact with each other. A finished design that looks good in black lines on a white background won’t necessarily look good when you add contrasting colours in a later stage of the design process. I have made this mistake previously and you can lose a lot of time and quality this way.

Don’t forget to set the background colour also to a colour that resembles you final background colour. The way the object interacts with the background colour is as important as the other colour interactions within the building itself. Here I chose a dark grey background because I knew I would make some sort of night scene.

Another mistake I made with this design: I didn’t decide what materials the different colours were going to become. As you can see below I chose a light grey colour for the windows, but I didn’t think about how I would translate this colour to a believable material in the final texturing. So I eventually ended up making these windows much more lighter and contrasting. The end result not too bad, but it is not really the design I was looking for in the first place. The lesson I learned: decide from the beginning what material each colour will become.

Next I made some quick sketches so I would have a rough idea on how I would make the environment in Mudbox. I wanted to create a strong foreground-background relationship. I wanted the rocks on the foreground to be pretty black so they would make the sense of depth stronger and so they would also match the building’s darkness and contrast.

I also applied a technique I have never used before. I drew some thick “edges” around the most important forms and I made them black. In the image underneath I gave these edges a red colour so you can see what I mean. It makes the forms more distinctive and more easy to separate from one another.

Adding chiaroscuro 2

Hugh Ferriss - Temple


I wanted to do another exercise with chiaroscuro and so I designed another building that is inspired by one of the drawings of Hugh Ferriss.

At first I tried to manage the chiaroscuro the same way I did in the previous image: with square holes in a simple plane. This might work when the camera is at eye-level, but it does not look realistic from above because you get square-shaped light beams that are visible as such.

What I did here is a better method. Below you can find a tutorial.

When most painters paint, or illustrators draw, they tend to move towards and away from their canvas or paper all the time. This is because you can more easily see the composition as a whole when it is visually smaller. I also tend to do this, but recently I had an epiphany. :-) What if in Sketchup I just make 3 different scenes with 3 different distances from the subject I am designing? This way you can switch between them constantly and you don’t have to move backwards from your screen all the time! Below you can find an image that shows this process and below that are some details of the final image.
