- the 2D logo (in the highest resolution you can find)
- 3D design software, such as ZBrush and Cinema 4D (which I use in this Instructable)
- a web-based 3D display platform, such as SketchFab (optional)
Step 1: Find a High-resolution Version of the Current 2d Logo
Step 2: Import the Logo Into a 3D Design App and Set Up the Reference Image
So now that my plan is clear, I'm going to fire up ZBrush and load the logo reference into Spotlight, to set it up for modeling in 3D. Before I start modeling, I check to make sure there's no distortion of the image - no squashing on any axis.
Step 3: Rough in the Basic Forms
Look for the basic shapes that make up the logo. In the Instructables logo, I see a box for the head, two semi-spheres for the ears, with thin horizontal tubes sticking out of them as antennas. The body looks like a flattened sphere stretched into a bell-shape, and so on. Once you see the basic forms, it's easy to drop these building blocks into place to create a rough version of the model, which you will later refine.
As you can see in the screenshot above, I've added in the basic forms of the body, head, and the features of the robot's right side, which I'll mirror to his left side as I refine the model in the next step.
Step 4: Build in the Fine Details of Your Model
Arms, fingers, legs, wheels, and antennae - now it's time to add them all in, and make sure your model has the right number of everything. At this point, I'm going designing everything symmetrically, focusing on modeling the structures as accurately as possible.
In the next step, we'll focus on adding character to the model by introducing its asymmetrical features and posing it as closely as possible to the 2D reference.
Step 5: Give Him Character: Modeling
As with human faces and bodies, this robot's asymmetries enhance this character. Note the asymmetries of his pose, of his eyebrows and mouth, and of his stance. These details bring the character to life.
Step 6: Give Him Character: Rendering
Cinema 4D's Sketch & Toon renderer will be a great way to recreate the logo's hand-sketched look. I'll show how how to do this in an update to this Instructable. Coming soon!
Step 7: Present Your Model to Your Client
One final thought:
