In this new series of post I will talk about learning to use Blender, the famous 3D computer graphics software. A series of tutorial for beginners/newbies (like me).
If you like computer graphics, at some point during your studies you will want to learn to use a 3D
content creation software. That’s why I started to study Blender, the most beautiful and famous open source 3D software
available for free in the market. In this series of posts I will guide you through its features with some tutorials
and references list. At the time of this writing the available version of Bender used for this tutorials is the 2.79.
All the tutorials are written using Blender on a MacBook Pro.
Let’s start from the user interface.
The default layout is composed of individual panels, and inside each one of them we can find an editor. The main editors are:
We can switch a panel from one editor to another by clicking on the icon that shows the current editor selected: a list with all the available editors will be shown and we can choose one of them.
On the left side of the viewport we can find a series of tabs that contain some operations, tools and actions we can
apply to the 3D window content. This tabs will change based on the fact that we selected or not an object and also
based on which type of object we selected. We can also show the object properties sub-panel by clicking the plus (+)
button on the right. That sub-panel gives us some information about the object we selected in the 3D window.
At the bottom of the 3D window we can find the 3D manipulator widget, that allows us to scale, rotate and translate object with the mouse drag.
Then we have the layer switcher, that will let us create layered scene (we will talk about layers in a future post).
We have also the viewport shading button, that let use choose the desired type of visualization we want for our scene:
Finally we have the editing interaction mode selector, that allow us to switch between editing mode:
The menus on the left of the editing mode selector will change accordingly to the mode selected.
To navigate in the 3D space, usually Blender require a 3 button mouse (we will see below how to emulate a 3 buttons mouse). Anyway, as we’re on a MacBook pro we can do the following basic operation with the “alternative” default mapping:
There are also some other basic useful 3D navigation commands:
You can change the user preferences by going to File -> User Preferences. Here you can modify settings for:
To be noted is the option “Emulate 3 Button mouse” in the input settings. This option let Blender emulates a 3
button mouse using the Alt button. Int this way you can use this setting to use Blender with standard keys for mouse.
That’s enough first post. See you in the second tutorial about selecting and translating objects.
