Blender 3D: Noob to Pro/Simple Vehicle: Wheel
|Applicable Blender version: 2.75a.|
There are 2 tutorials for the tires. This and the previous tutorial. The first is basic but this is an a more complicated tutorial with a total of 4 different versions.
- 1 Techniques
- 2 Model the tire
- 3 Model the hubcap
- 4 Extra
You should already know how to:
- Make a mesh
- Navigate the viewport
- Create, edit materials
This section will recap and introduce:
- Forming faces
- Merging vertices
- Object naming
For our premise, envision jeep tires. They're not too sleek but rather rugged for all kinds of terrain. We need a tire that can handle any obstacle in its way.
During this tutorial we will be using orthographic view.
Model the tire
Hit NUM1 to set front view ( XZ coordinates ), then delete the cube.
Create the outside of the tire
Add a cylinder Shift+A > Mesh > Cylinder then in the tool shelf click on "align to view", use 32 vertices, set the radius to 4, depth to 3, and choose Cap Fill Type: "Nothing".
Create the inside of the tire
Change to NUM1 view and make sure you are in Edit Mode.
Select all vertices, hit the "E Key" and directly after that the "ESC key" to make the new faces, then "Alt+EKEY" and choose "Individual faces)" and extrude the individual faces into the circle by moving the mouse.
You may either type in -1.2 and hit enter, or Hold SHIFT CTRL while extruding the faces until the sides come in -1.200 units. Now remove doubles by going into edit mode, select all and then WKEY -> Remove Doubles.
Subsurf the tire
Now it's time to make the tire look like a rugged tire.
Return to Object Mode, and apply a subsurf modifier (use the Modifier menu in the properties header (it looks like a wrench) click on "Add Modifier" and select Subdivision Surface - select VIEW level 1 or 2 to the mesh. The tire will now look like a bead necklace.
Crease the edges
A little creative use of creases will restore our tire.
Check that Limit Selection to Visible is off.
Enter Edge Select mode
Bring up the circle selection tool (AKEY to unselect all, then CKEY).
Use the scroll wheel to change the circle selection size to be in the center of the tire, between the inside and outside edges. This will select all of the inside edges, as well as the triangles on the side of the tire, as in the picture below. Then type "Enter"
Now press SHIFT+EKEY to Crease these edges, you can type 1.000, and press ENTER, or hold CTRL to pull in steps till you see 1.000 in the status bar at the bottom of the view window.
Model the hubcap
The tire is almost done. Let's add a simple hubcap to it.
Create a cylinder
Be sure you're in Edit Mode
Hit AKEY, once or twice till the wheel is selected
Hit NUM1 for front view
Press SHIFT+SKEY, from the popup menu, choose "Cursor to Selected", to put the cursor at the center point of the existing tire
Hit Shift+A => cylinder with 32 vertices, radius of 1.9, depth of .5, and choose Cap Fill Type: "Nothing", click on the checkbox of "align to view".
Hit NUM7 for top view
Hit GKEY, then YKEY, then type 2.2, and hit ENTER
Create the outside of the cap
Hit AKEY once, so that nothing is selected
Hit NUM7 for top view
Zoom in with the MMB till the hub cap fills the view
be sure you're in Vertex select mode
Make sure "Limit selection to Visible" is off
hit BKEY for box select, then holding the LMB drag the box along the top edge of the hubcap.
Hit ALt+EKEY on the popup select Edges only, then hit ESC, to create the edges we will need
Hit SKEY, then SHIFT+YKEY to only move in the XZ axis, then type in .35, and hit ENTER
Hit GKEY, then YKEY to only move the Y axis, then type in .35, and hit ENTER
Create the Axle Cover
We'll merge these vertices together to create a flat surface.
Hit Alt+EKEY, on the popup select edges only, then hit ESC, to create the edges we will need
Hit ALT+MKEY on the popup pick at center. Blender will reduce the 32 vertices to 1.
Hit NUM3 for side view
hit GKEY, then YKEY, to only move the Y axis, then type in -0.4, and hit ENTER
Final sizing of hub cap to tire
The final mesh editing is to scale the hub cap to a size that is slightly larger than the hole of the tire.
hit NUM7 for top view
position the mouse over the hubcap, and press the LKEY to select the entire hubcap
Hit SKEY, then SHIFT+YKEY to only move the XZ axis, then type 1.48, and hit ENTER
Hit NUM3 for side view
Hit GKEY, then YKEY, to only move the Y axis, then type -1.11 (use -0.77 if you want your hubs sticking out), and hit ENTER
Renaming the Wheel
The last thing to do is to rename the wheel so we can find it easier later.
Enter Object mode and select the wheel only.
In the outliner window you'll see the tire called "Cylinder". This name was created because we started with a cylinder mesh.
Click on the name with the right mouse button and click on rename rename the object to something like 'wheel'. Save your file where you'll find it later and continue to the next step.
Change the materials to make it look like a tire. One object can have multiple colors/textures, as you will learn in future tutorials.
