Not knowing 3D sucks. At some point I wanted to design the cup and I went through a whole struggle illustrating it in Photoshop.
I came up with the idea of having a cup in a shape of a spiral, so when you pour coffee it goes down the spiral, almost like a tornado. I did a quick sketch trying to understand the curves and how it actually might look.
Despite of having a very clear image in my had I could not illustrate it right. I asked a friend of mine who knows 3D to make some quick wireframe renders, so I can actually understand the shape. I could not explain to him visually exactly how it works/looks, so I went to the art store and bought some clay hoping I could make a rough shape with my hands.
After taking some photos of the clay model it helped me understand a little bit what the shape really is and where do curves go on the object. I brought it back to Photoshop so I could make a more accurate illustration.
This is the rough 3D wireframes my friend sent back to me. At least here I was able to see the shape of the cup, where do shadows and highlights go etc. It was a little too "sharp" on the edges and I wanted to achieve a more "fluid" look.
Now, based on 3D wireframes I started illustrating it again in Photoshop step by step. Click on the gallery images to see the progression.
And here's the final angle created in Photoshop.
To make sure that the shape actually makes sense, I had to illustrate it from different angles.
And a quick logo
The next step for me is to find someone to create a new 3D model so I can 3D print it in porcelain and test the real object out — see how stable it is and how comfortably it sits in a hand. I know it would be hard to wash, but that will not stop me :)
Final project is now in my Online Museum of Artifacts on repponen.com
