I am sure you have already installed Blender and know how to launch it. If not, then please refer to the "Installation" section in the appendix of this book. Basically the installation procedure consists of unpacking the archive onto your hard disk, and then starting it from there. The start procedure will depend on your operating system.
Once you have started Blender, it presents you with a screen with a big 3D view and many buttons. This is the default scene in Blender. Later in this book, you will see how to customize that default scene to suit your needs.
Usually, after experimenting with a few mouse clicks in a new program, one wants to load up some scenes to test what can be done with the program. The easiest way to do this in Blender is to use the "File" menu at the top of the screen. Click on "File" and choose "Open". The keyboard shortcut for opening a new file is F1 . Blender makes extensive use of shortcuts for speedier functionality.
You will see that you have a FileWindow from which you can browse through all of the files on your computer. Pressing and holding the MenuButton with the left mouse button (LMB ) will give you a choice of recently browsed paths and, on Windows operating systems, a list of your drives.
The directory you are currently in is shown in the top text-field. The ParentDir button allows you to go up one directory.Using these possibilities, go to your CD-rom drive and browse for the folder containing the file "Stage.blend" . Now click with the middle mouse button (MMB ) on the filename "Stage.blend" . The file will be loaded immediately. Alternatively, you can click with the left mouse button (LMB ) and then confirm your selection with ENTER .
|Blender works best with a 3-button mouse. To compensate for the lack of a middle mouse button, hold ALT and press the left mouse button instead.|
The screen will now show four windows: a top view on the top-left, a camera-view on the top right, a side-view on the right middle. All three 3DWindows visualize the 3D space. The wide window at the bottom is the ButtonsWindow. In this instance it contains the DisplayButtons that control the rendering.
Just click on the big "RENDER" button in the ButtonsWindow and Blender will render the actual camera view and display it. You can see a brick wall at the back, and a wooden stage lit by a spotlight. This will be our stage for the next steps in this quick tour of Blender. Close the render-window with ESC , or F11 .
(also as single
pictures avaible: images/Toolbox.tga and
Move your mouse down to ">UVSphere" (it will be highlighted in blue) and click again the LMB . A pop-up menu will prompt you how many segments the sphere should have. Just click on "OK" for now. Leaving the pop-up menu with the mouse will cancel the creation. A second pop-up will now appear and ask for the number of rings for the sphere. Just click on "OK" as you did before.
The sphere is now in the so-called "EditMode", a mode where we can edit every single point of the sphere in order to shape it the way we like. For now we want to manipulate the object as a whole and so we'll need to leave the EditMode. Press TAB and you will see the sphere drawn in pink in the 3DWindows and shaded in the Camera-view.
You can now do another rendering (F12 , then close with ESC or F11 ) and watch how the sphere casts shadows onto the scene.
So far the sphere looks a little bit blocky. You can see the single polygons that make up the appearance of the sphere. We will change this now. Press F9 , and the ButtonsWindow will change to EditButtons . Here we have several buttons with which we can change mesh object, but for now we only need one. Locate the "Set Smooth" button in the third row of buttons in the EditButtons, and click it with the LMB (left mouse button). The sphere is now drawn smooth in the shaded camera view, and in a rendering.
|You can use the 3DCursor to place an object in 3D space without using multiple views. Position the 3DCursor with a LMB click. What is very helpfull here is that you can snap the cursor to the grid, other objects, or vertices (SHIFT-S ).|
Now select the Sphere in one of the 3DWindows with the RMB (right mouse button). The color of the wireframe views of the sphere will change to purple, indicating the selected objects in Blender.
Once you have selected an object, you can manipulate it. Move your mouse cursor to the big 3DWindow (the top view) and press GKEY to start the grab mode. The sphere turns white and follows the movements of your mouse in the window. In the other windows, you can see that it only moves in the two directions that you can control with the mouse. In this instance it moves around on the stage without either moving up or down.
When you are satisfied with the position of the sphere, click with the LMB to confirm the new position. If you don't want to change anything, or if you should accidently move an object, click with the RMB (right mouse button) to cancel.
|ESC and the RMB both cancel Blender operations.|
A clutch of Buttons will appear in the ButtonWindow, but don't worry -- we do not need to touch them all just now. The most prominent property of a surface is the color. Locate the color sliders to the right of the material preview.
The color sliders are labeled with "R,G, and B" which stand for the base colors Red, Green and Blue. You can adjust each of them, in a range from 0.0 to 1.0, to get every color you could possibly want. Also, you can use a different way of setting up colors if you click on the "HSV" button. The color slider will change to "H, S and V", with the "H" slider you choose a hue, and then adjust its saturation with "S", and its brightness (Value) with "V". Experiment with both of these methods for choosing a color and see which suits you best. I have choosen a gold tone, which is a setting of R=0.80, G=0.74 and B=0.00 on the RGB sliders.
With the sphere selected, press F6 to switch to the TextureButtons. Locate the MenuButton again and add a new texture in the way we did for the material. Now Bender presents you with the built-in texture types.
Choose a marble texture by clicking on the button "Marble". Blender shows you a preview of the texture in the TexturePreview on the left of the window.
For the purpose of this quickstart, we won't care too much about the settings we'll just go with the defaults. You can now do a render by pressing F12 to see a purple and gold marbeled sphere. To change the color of the marble texture go back to the MaterialButtons with F5 and locate the color settings for textures to the right side of the window.
You can now change the color of the texture, just as we did for the material. If you choose to use the HSV color setting you will also see the HSV sliders here.
|You should name objects, materials, textures, etc., in Blender to help you keep track on them in bigger scenes. Just click on the appropriate TextButton in the header of a window and edit the name with the QWERTY keys. A special function here is the little button with the car on it, if clicked upon, Blender names the object itself.|
Select the sphere, move your mouse cursor to the big 3DWindow (the top view), and press GKEY to move it. Move it to the left and watch the camera view while so doing. The sphere should be outside the outer dotted line in the camera view. This dotted line denotes the area that will be rendered by Blender.
Now we'll instruct Blender that this will be the initial position of the Sphere. Press IKEY and choose "LOC" from the appearing menu.
Blender will now remember this position, but we still have to tell it where the sphere should go. For that we need two pieces of information: the new position, and the time when the sphere should reach that position.
We already know how to do this for the location. The time we set with the 'FrameSlider' that is located in the header of the ButtonsWindow. It now is at frame one. Press UPARROW six times and look at the FrameSlider. It has advanced 60 frames. You can now move the Sphere to the final position that you want it to be, and insert a new keyframe with IKEY (again choose "LOC").
|Blender counts time in frames. The 60 frames we have used here are roughly equal to two seconds of animation.|
The ButtonsWindow we will need for this step is accessed by pressing F10 . The DisplayButtons will appear.
The first thing we need to tell Blender is precisely where the calculated pictures, or the animation, should be stored. This is done using the buttons on the left in the DisplayButtons. In the input field labeled "Pics", you can enter a directory and filename in which Blender should store the pictures (or animation). Click on the square button to the left of the textfield to get a FileWindow in order to browse for a directory and enter a filename.
|Make sure the directory you enter exists, otherwise Blender will not save any of your pictures.|
Now enter a size for our animation using the size buttons in the DisplayButtons. Bigger sizes will, of course, increase the rendering time, so if you don't have a fast computer, or your patience is limited, don't choose too big a size. Under the size buttons you can tell Blender in which file format you want to save the animation. For now, I suggest we use "AVI raw".
Below the "ANIM" button, you can adjust the length of the animation. For the purpose of this quickstart, it should be "Sta: 1" and "End: 61" because our animation lasts for that amount of time measured in frames.
Now click "ANIM" with the LMB , and Blender will render every single picture of the animation. When Blender has finished, press "PLAY" and Blender will play back the rendered animation.
|You can always cancel the rendering with ESC if you don't like the result, or if it takes too long.|
