This is the first in a series of tutorials designed to introduce one to Blender. This particular one explains what's required to know before the reader can begin to play around with Blender productively. It was written Oct-18-2002. It uses Blender 2.25, with Windows 98, though the operating system should not matter too much.
Welcome to the world of Blender! If you haven't downloaded a copy yet, get one from www.blender.org, it has been opensourced and people are playing around the sources, but for right now it's a good idea to grab Blender Publisher 2.25, not one of the user compiled ones.
You should probobly register on the elYsiun.com forums, becuase this is a great place to ask questions and to show off your work. Just make sure to be polite, saying "pl3aZ HeLP me make somE COOL 3d!" will not get you very far, infact, it will make people listen to you less. Noone is forced to help you, so asking politely will get you quicker answers. "Please" and "thank you" often will impress people, whereas demanding will get you flamed. Also, don't expect to become a master overnight, working with Blender takes time and practice, be can be very rewarding. A lot of learning how to use Blender involves learning hotkeys. They make modeling much faster than any other interface, but there are a lot of them, just take it one bit at a time and you'll have them learned in no time! Now that you've downloaded Blender and registered on ElYsiun, we're ready to go! Also, remember the Golden Rule of Blender, "Keep one hand on the keyboard and one hand on the mouse."
Open up Blender and take a look around. It's should look something like this:
Look at all of those buttons! Relax, most of them are for specific purposes, and will not be required for a long time. Let's take a look around.
1. These are the directory settings. It would be a good idea to leave them, because we don't need them yet.
2. This is the OSA. Leave it on, at about 5 or 8, or if it's off, turn it on. This smooths out your pictures, so they have no jaggy edges. This feature is often missed by novices.
3. These are some animation related buttons, again, these are of no use right now, but they'll be pretty important later.
4. These buttons change how your image is saved. Quite useful, and will be explained later on.
5. All of these buttons except for the "Unified Renderer" change the size and aspect of the saved image or animation. The Unified Renderer is another renderer, one that will improve specific parts of the images, but it's slow and it has some problems with particular things. Overall you won't be using the "Unified Renderer" button very much.
Moving on up we get to the bar about in the middle of the screen...
1. In order from left to right we have the "Current Window Type" button that selects what the top half is. We won't be needing it yet. After that is the Fullscreen button, it maximizes the top half. Finally, we have the Home button, if, in the future, you ever scroll and zoom so much you can't see where you are, press it to go strait back to the camera!
I will explain some of the concepts and terms I will be using. This will be old news if you have been working in CG before.
Individual models are refered to as objects. An example of an object:
See all the little polygons making it up? These are called "faces". The individual faces can be seen more clearly here:
Next comes edges, but edges aren't very important in Blender, so we'll skip strait to the building blocks of every face and object, the vertices (singular "vertex"). They are also called "points", depending on the person, but they're called vertices within Blender. They are basicly points in 3D space, each having it's own X, Y, and Z location values. Some are connected to form a face. Our monkey friend will show off these vertices:
Now, with that covered, let's go over some of the most useful hotkeys.G: "Grab", this moves around your model. You can right-click it and drag, but pressing "G" and moving your mouse is more accurate. Holding your third mousebutton (afterwords, note that if you don't have a three button mouse, to simulate the third mouse button, hold Alt and press the First Mouse button. Holding Ctrl will lock it to the grid.
Let's get started on some basic modeling!
Press Space to bring up the menu. Click Add, then click Mesh. Ignore the tempting "Monkey" button for now. Click the Cube button. You should see something like this:
If you don't have a lamp (the little yellow circle), go back to the Space menu and hover over the MESH tab on the left, this takes you back to the main menu. Click Add then click Lamp. Position it a little bit behind your camera (the triangle shape) and a little bit about the camera. Now click "F12", the button to render. You should see something like this:
That's kinda boring, huh? How about we make it slightly more interesting! Experiment with it, rotating it, scaling it and moving it. Here are two different renders you could get:
Still not exciting for ya? Well, delete the boring cube by selecting it and pressing "X" or "Delete", whichever you choose, I personally use X because it's so close to the other keys.
Let's learn some basic modeling techniques by starting small. How about a cup? Let's make a nice glass one. First thing to do is create a Cylinder, go to top view (7) and make one the same way you made the Cube, just select Cylinder instead. Press ok, when it says, "Vertices: 32". Change to front view (1). You should see something like this:
Here's where the fun begins. Press Tab to switch to edit mode. Press B and select all the bottom vertices. Bring them up closer to the top and scale them up a bit. Like this:
Now let's introduce the concept of Extruding. This is one of the most used commands for mesh modeling. It's much easier shown than explained. Put your mouse over the vertices, and press E. When it prompts, press "Extrude". Now move your mouse down more. Hold down Ctrl to make sure it doesn't move to the side. See? Look:
This is a very useful little feature. It's moved down a bit too far, so lets move the vertices back up. Press "G", but don't use your mouse to go up. We have to be very accurate, so hold Up. Stop about half way and size it up a bit. Like this:
Ok, so lets do this a few more times, but making sure to scale them up a little bit until we reach the center then we begin to scale down. Like this:
That wasn't too hard was it? We're starting to run out of room, so let's pan down a bit. Hold Shift and click with Mouse 3, to move down. Let's continue to move downwards, making a nice glass profile. Be sure to zoom out once if it starts to take up the whole 3D window. Here's what I got, but you should feel free to do your own style:
Ok. When you're happy with the model, use Tab to switch back out of edit mode. It's a bit too big right now to render so scale it down a good bit. Go to side view (3) and move it a little distance away from your camera. Now press 0 to go to Camera View. Does it fit in the two boxes? If not, scale it down some and move it until it does. Here's what I got:
Go to EditButtons (press F9) and find the button that says "Set Smooth". This get rid of unsightly faces showing, making it a smooth shaded model. Now press "Z" to switch to OpenGL mode. What a nice model! Try rendering once more (press F12.) Much better. Here's my image:
Now, notice the top? See how it's so sharp and thin? We can fix it! Select the top row of vertices. Extrude them down, following the outline of the glass, rounding out when you read the end. Here's what I mean:
Press that "Set Smooth" button and then enable the button "SubSurf" and keep the SubDiv at 1. Render again. By now, it should look pretty nice. Here's the final image:
See the File menu at the top? Click it and click save, or just press Ctrl-W (more hotkeys!) to save it. Name it something like "glass.blend". To save it as an image it render it, go back to Blender, go to display buttons (F10), and set the box that says "Targa" to "JPEG". Now go to the File menu and select "Save Image." There you go. Go show it to your friends!
In the next tutorials we'll cover making a table to go under our glass, lighting it with shadows, and texturing both, including making the glass clear. Until then, use my Tutorial Links and find a tutorial suitable for your progress. Be careful not to jump ahead though.
