Introduction:
Blender is a free and open-source 3D computer graphics software product used for creating animated films, visual effects, interactive 3D applications or video games. Blender's features include 3D modeling, UV unwrapping, texturing, rigging and skinning, fluid and smoke simulation, particle simulation, soft body simulation, animating, match moving, camera tracking, rendering, video editing and compositing. It also features a built-in game engine.
Blender's user interface incorporates the following concepts:
1. Editing modes:
The two primary modes of work are Object Mode and Edit Mode, which are toggled with the Tab key. Object mode is used to manipulate individual objects as a unit, while Edit mode is used to manipulate the actual object data. For example, Object Mode can be used to move, scale, and rotate entire polygon meshes, and Edit Mode can be used to manipulate the individual vertices of a single mesh.
2. Hotkey utilization:
Most of the commands are accessible via hotkeys. Until the 2.x and especially the 2.3x versions, this was in fact the only way to give commands, and this was largely responsible for creating Blender's reputation as a difficult-to-learn program.
3. Numeric input:
Numeric buttons can be "dragged" to change their value directly without the need to aim at a particular widget, thus saving screen real estate and time. Both sliders and number buttons can be constrained to various step sizes with modifiers like the Ctrl and Shift keys.
4. Workspace management:
The Blender GUI is made up of one or more screens, each of which can be divided into sections and subsections that can be of any type of Blender's views or window-types. Each window-type's own GUI elements can be controlled with the same tools that manipulate 3D view.
Advantages:
The first and most obvious advantage to Blender is of course the price. Being open source, and distributed for free, you can use Blender free of charge.
It provides full animation tools, high quality rendering using a built-in raytracer, UV unwrapping tools, a physics engine, composition tools, and even a real-time game engine.
Disadvantages:
Even though Blender received a face-lift and now has a better, more intuitive user interface for new users, it still remains a daunting first experience.
The other negative is the small user base. The fact remains that very few studios use Blender, with most of them instead relying on professional solutions.
Conclusion:
Thus we have studied about blender.
