# 01 – Quick Look
In this tutorial we are going to take a quick look at Blender.
But what is Blender? Blender is a professional free and open source 3D computer graphics software. With Blender, you can make detailed 3D models, 3D animations, games and much more!
I’m using Blender 2.71, as you can see in the splash screen, located at the middle of picture 1. If you are using a different version, this splash screen may look different. You can click in the splash screen to make it disappear.
Blender’s interface is composed of different windows called editors. For example, the big window containing a cube with three colored arrows is an editor called 3D View. And the tall thin window at the right of the screen is an editor called Properties.
Each editor has its own header located at its top, like the properties editor, or at its bottom, like the 3D View editor. You can change the editor type clicking on any button that control the editor types.
The interface can be changed. There are interface presets based on activities you may want to focus on. You can click on the box at the right of the “Help” menu option to select different presets, like the Animation preset, if you want to focus on animations, or the UV Editing preset, if you are working with textures. Each interface preset offer different options.
Some headers have tab-like buttons called Context Buttons. They give access to some options. For example, the Materials Context Button gives access to options related to objects materials. The Modifiers Context Button gives access to several modifiers. We will see more about those in the future.
There are also areas called Regions. Regions group together panels, like the Transform Panel, and controls, like the Translate, Rotate, Scale and Mirror Controls.
Sometimes, a Region may be hidden. There are plus sings indicating that a region is hidden. You can press the plus sign or the letter N in your keyboard to show the hidden Region. You can press N again, or left click its edge and drag to hide it again. Like the right region, you can hide or expose the left region using the letter T, the plus sign that appears if you hide the region, or clicking and dragging its edge.
In Blender, there are different types of controls, like buttons, checkboxes, sliders and dropdown menus that you can use to choose or change different options. You can render an image clicking in the Render button, You can Turn on or off Anti-Aliasing for your render checking or unchecking the Anti-Aliasing checkbox, You can set a render resolution in the Resolution sliders and You can choose the different Render presets in the Render Presets dropdown menu.
