カメラマッピングを使って2D素材で3D空間を表現する実験(Camera mapping with Cinema4D)

ジョナサンです。
初めての投稿ですが、英語でごめんなさい 🙁

Lately I have been experimenting with Cinema 4D how to create a 3D town while still keeping the density of a 2D illustration. Above is a 6 seconds travelling test.

First, I used an illustration made last year called ‘Kampung Ayu’ (カンプング アユ・甘い町) and separated in several layers (houses, highway, vehicles, background, etc …)

For the static elements (street, houses, highway) I used a technique called ‘Camera Mapping’.

I modelled a 3D Town made of simple boxes and planes, then I projected each layer from the illustration on each box and plane according to the movements of the camera.

We could have made more detailed 3D elements, but if the 3D was is too strong, we would lose the illustration’s atmosphere and it wouldn’t look right.
So I tried to find a balance between the needed 3D elements and the 2D atmosphere.

In that way, we get the feeling of moving within the town and still keep the density of the original crafted illustration.

Now let’s talk about the elements we expect to move like the vehicles and the blue food stall (青い屋台).
As movements in the 3D town are limited because of the ‘Camera Mapping’ technique, I used a conventional UV mapping with more detailed 3D models.

Compared to the town, we lost some of the original illustration’s style but we are able to move around them and make them move with a lot of ease, and visually it still looks right.

The next step on this experiment is to make this 3D town alive.
For this I may animate characters with conventional 2D frame/frame animation or create 3D characters and make them feel like 2D crafted characters.
The second solution seems more fun!
