C07- Modeling Flower pot
Let us now move on ahead a little more with modelling. We have seen that every object is made up of many parts. Like a cube is made from 6 different squares. Every square in it is made from 4 points joined by 4 lines. These squares, lines and points are called polygon, edge and vertex inside a 3D software. We can then also say that the cube is made from 6 polygons, 12 edges and 8 vertices. The shape of the cube is decided from these fundamental elements. Every 3D object is made from these fundamental elements. So they are also called ‘elements of objects’.
Q: But why are these ‘elements’ relevant to us? We use the cube directly.
This is very useful. Even if we get a cube or sphere readily in Blender, these fundamental objects are very limited. Most of the time we need to use more complex shapes. Then we use our fundamental elements to create new shapes, similar to how we used the ‘mechano’ toys when we were kids. We will be taking a glimpse at this today. We can use the same ‘elements’ in blender today.
There is a button named ‘Object Mode’ in the footer bar at the bottom of the viewport. Click on it and select the ‘Edit Mode’. This will show you the elements of the cube. This is called the edit mode as you can go to vertex level to edit the object. After editing you can again go back to the ‘Object Mode’.
There is also a key board short cut to go to the ‘Edit Mode’. While, the mouse is with in the viewport you can press the ‘Tab’ key on the key board to go to the ‘Edit Mode’. The ‘Tab’ key acts a toggle between the ‘Object’ mode and the ‘Edit’ Mode.
After going to the edit mode, we can see the vertices of the object. We can again right click on any of the vertex to select it.
You will see 3 more buttons for ‘Vertex, Edge and Polygon’ in front of the ‘Edit Mode’ button. Through this we can select any of the 3 elements.
We have a shortcut for ‘Vertex, Edge and Polygon’ also. While in Edit Mode if we press ‘Ctrl + Tab’ we get a small list. We can enter any of the element mode from this list.
We can then edit the vertices or edges or faces to create different shapes. In reality, this is 3D modelling but we are getting into very technical territory. Lets start creating something, it will help you understand better.
We will take our cube to work on. While the cube is selected, press ‘Tab’. This will start its edit mode. Now going into polygon mode, select the top polygon. Now if you press ‘E’ and move the mouse, you will see a new polygon created above it. There is a ‘Extrude’ button for this in the ‘Tool Panel’ on the left. Extrude and check it for yourself.
Let us create a flower pot using the same method. You will be able to understand it easily.
First delete the cube and take a Cylinder instead.
Go to its polygon edit mode. Select the top polygon and move it down.
Q: Can we use the ‘G Z’ key board short cut here?
Definitely! Blender allows us to use such shortcuts everywhere.
We can also scale this polygon just the way we can move it. Now as shown in the image below, We can create a new shape using ‘S’ and ‘E’ i.e. scale and extrude, one after the other.
Delete the top most polygon in the end.(Select the polygon and press X, this deletes the polygon). You will now be able to see the shape of a flower pot.
So this is why the edit mode is used, to create different models. In reality there are many more tools, but for now we will just consider this flower pot.
As shown in the image below, exit the Edit Mode and select the Smooth options from the Tools panel. This makes the surface of the object look smooth.
Q:I never thought that the polygon, edges and vertex would be of so much use.
Most of the modelling is done using edit mode and we get a different modelling method from these basic elements.
Now for the final touches. We used the bevel modifier on the cube in the last post. We will now use some more modifiers.
We will use 2 modifiers from our modifier panel. First is solidify, which gives the pot some thickness and solidness. Second modifier is ‘Subdivision Surface’. This is a little different modifier. This will make our pot appear to be a lot more smoother. This modifier divides each polygon into multiple polygons (subdivides them)
Q: Wow, the pot looks great now.
