The Dutch animation studio NeoGeo not associated with the Neo Geo video game brand started to develop Blender as an in-house application, and based on the timestamps for the first source files , January 2, is considered to be Blender's birthday.

The name Blender was inspired by a song by the Swiss electronic band Yello , from the album Baby which NeoGeo used in its showreel. This also meant, at the time, discontinuing the development of Blender. In May , Roosendaal started the non-profit Blender Foundation , with the first goal to find a way to continue developing and promoting Blender as a community-based open-source project.

On July 18, , Roosendaal started the "Free Blender" campaign, a crowdfunding precursor. Today, Blender is free and open-source software, largely developed by its community as well as 15 employees employed by the Blender Institute.

The Blender Foundation initially reserved the right to use dual licensing , so that, in addition to GPLv2 , Blender would have been available also under the Blender License that did not require disclosing source code but required payments to the Blender Foundation. However, they never exercised this option and suspended it indefinitely in In , the integrated game engine for making and prototyping games was removed in the release of 2.

Nevertheless, they put out one more release, 2. As a sort-of easter egg , and last personal tag, the artists and developers decided to add a 3D model of a chimpanzee head, although it is called a " monkey " in the software.

Suzanne is Blender's alternative to more common test models such as the Utah Teapot and the Stanford Bunny. A low-polygon model with only faces, Suzanne is included in Blender and often used as a quick and easy way to test materials, animations, rigs, textures, and lighting setups. It is also frequently used in joke images. Blender 2.

The following table lists notable developments during Blender's release history: green indicates the current version 2. Blender has support for a variety of geometric primitives, including polygon meshes , fast subdivision surface modeling, Bezier curves , NURBS surfaces , metaballs , icospheres , text, and an n-gon modeling system called B-mesh.

Blender has multi-res digital sculpting , which includes dynamic topology, maps baking, remeshing, re-symmetrize, and decimation. Blender can be used to simulate smoke, rain, dust, cloth, fluids, hair and rigid bodies.

The fluid simulator can be used for simulating liquids, like water hitting a cup. The particle physics fluid simulation creates particles that follow the Smoothed-particle hydrodynamics method. A particle system that includes support for particle-based hair. Real-time control during physics simulation and rendering. Keyframed animation tools including inverse kinematics , armature skeletal , hook, curve and lattice-based deformations , shape animations , non-linear animation, constraints, and vertex weighting.

Internal render engine with scanline rendering , indirect lighting, and ambient occlusion that can export in a wide variety of formats; A path tracer render engine called Cycles, which can take advantage of the GPU for rendering.

Cycles supports the Open Shading Language since Blender 2. Eevee is a new physically based real-time renderer. It works both as a renderer for final frames, and as the engine driving Blender's realtime viewport for creating assets.

Blender allows procedural and node-based textures, as well as texture painting , projective painting, vertex painting , weight painting and dynamic painting. Blender has a node-based compositor within the rendering pipeline accelerated with OpenCL. Blender also includes a non-linear video editor called Video Sequence Editor VSE , with support for effects like Gaussian blur , color grading , fade and wipe transitions, and other video transformations.

However, there is no multi-core support for rendering video with VSE. Integration with a number of external render engines through plugins. The Blender Game Engine was a built-in real-time graphics and logic engine with features such including collision detection , a dynamics engine, and programmable logic. It also allowed the creation of stand-alone, real-time applications ranging from architectural visualization to video games.

In April it was removed from the upcoming Blender 2. Blender features an internal file system that can pack multiple scenes into a single file called a ". Blender organizes data as various kinds of "data blocks", such as Objects, Meshes, Lamps, Scenes, Materials, Images and so on.

This allows various data blocks to refer to each other. There may be, for example, multiple Objects that refer to the same Mesh and making subsequent editing of the shared mesh result in shape changes in all Objects using this Mesh. Objects, meshes, materials, textures etc. Most of the commands are accessible via hotkeys. There are also comprehensive graphical menus. Numeric buttons can be "dragged" to change their value directly without the need to aim at a particular widget, as well as being set using the keyboard.

Both sliders and number buttons can be constrained to various step sizes with modifiers like the Ctrl and Shift keys. Python expressions can also be typed directly into number entry fields, allowing mathematical expressions to specify values. Blender includes many modes for interacting with objects, the two primary ones being 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.

The Blender GUI builds its own tiled windowing system on top of one or multiple windows provided by the underlying platform. One platform window often sized to fill the screen is divided into sections and subsections that can be of any type of Blender's views or window-types. The user can define multiple layouts of such Blender windows, called screens, and switch quickly between them by selecting from a menu or with keyboard shortcuts.

Each window-type's own GUI elements can be controlled with the same tools that manipulate 3D view. For example, one can zoom in and out of GUI-buttons using similar controls, one zooms in and out in the 3D viewport. The GUI viewport and screen layout are fully user-customizable. It is possible to set up the interface for specific tasks such as video editing or UV mapping or texturing by hiding features not used for the task.

Cycles is a path-tracing render engine that is designed to be interactive and easy to use, while still supporting many features.

Cycles supports GPU rendering, which is used to speed up rendering times. Multiple GPUs are also supported, which can be used to create a render farm — although having multiple GPUs doesn't increase the available memory , because each GPU can only access its own memory.

The integrator is the core rendering algorithm used for lighting computations. Cycles currently supports a path tracing integrator with direct light sampling.

It works well for a variety of lighting setups, but it is not as suitable for caustics and certain other complex lighting situations. Rays are traced from the camera into the scene, bouncing around until they find a light source a lamp, an object material emitting light, or the world background , or until they are simply terminated based on the number of maximum bounces determined in the light path settings for the renderer.

To find lamps and surfaces emitting light, both indirect light sampling letting the ray follow the surface bidirectional scattering distribution function, or BSDF and direct light sampling picking a light source and tracing a ray towards it are used. They consist of three shaders to define the mesh's surface appearance, volume inside, and surface displacement. The surface shader defines the light interaction at the surface of the mesh.

One or more bidirectional scattering distribution functions, or BSDFs , can specify if incoming light is reflected , refracted into the mesh, or absorbed.

When the surface shader does not reflect or absorb light, it enters the volume light transmission. If no volume shader is specified, it will pass straight through or be refracted, see refractive index or IOR to another side of the mesh.

If one is defined, a volume shader describes the light interaction as it passes through the volume of the mesh. Light may be scattered , absorbed, or even emitted [ clarification needed ] at any point in the volume.

The shape of the surface may be altered by displacement shaders. In this way, textures can be used to make the mesh surface more detailed. Depending on the settings, the displacement may be virtual — only modifying the surface normals to give the impression of displacement also known as bump mapping — real, or a combination of real displacement with bump mapping.

Real-time PBR renderer. Using the default 3D viewport drawing system for modeling, texturing, etc. Free and open-source : [62]. Blender's non photorealistic renderer. It was removed from Blender in version 2. An add-on by Fabio Russo; it overwrites materials in Blender Internal or Cycles with a clay material in a chosen diffuse color. Included in Blender version 2. Since the opening of the source code, Blender has experienced significant refactoring of the initial codebase and major additions to its feature set.

Improvements include an animation system refresh; [69] a stack-based modifier system; [70] an updated particle system [71] which can also be used to simulate hair and fur ; fluid dynamics; soft-body dynamics; GLSL shaders support [72] in the game engine; advanced UV unwrapping; [73] a fully recoded render pipeline, allowing separate render passes and "render to texture"; node-based material editing and compositing; and projection painting.

Part of these developments were fostered by Google 's Summer of Code program, in which the Blender Foundation has participated since Official planning for the next major revision of Blender after the 2. Blender is extensively documented on its website, [81] with the rest of the support provided via community tutorials and discussion forums on the Internet.

The Blender Network provides support and social services for Blender professionals. Additionally, YouTube is known to have many video tutorials available. Due to Blender's open-source nature, other programs have tried to take advantage of its success by repackaging and selling cosmetically-modified versions of it.

Since , every 1—2 years the Blender Foundation has announced a new creative project to help drive innovation in Blender. In September , some of the most notable Blender artists and developers began working on a short film using primarily free software , in an initiative known as the Orange Movie Project hosted by the Netherlands Media Art Institute NIMk.

The codename, " Orange ", in reference to the fruit, started the trend of giving each project a different fruity name. The resulting film, Elephants Dream , premiered on March 24, On October 1, , a new team started working on a second open project, "Peach", for the production of the short movie Big Buck Bunny. This time, however, the creative concept was totally different.

Instead of the deep and mystical style of Elephants Dream , things are more "funny and furry" according to the official site. The game is titled Yo Frankie!

Blender 3D: Noob to Pro/Tutorial Links List

One of the most recent additions to Cycles render engine has been a toon shader. Many people seem to be interested in using it, but aside from the links shown here , there is little to no information about it, so they must resort to personal experimentation. This tutorial aims to teach readers how to use this toon shader to create renders with a comic style, and will be based on this simple scene as an example:. The first step will be setting up our lighting, which will be basically a key light and a fill light. Both lights will be point lights with 0 size. Any light with a size different to zero will create gradients in our shading.
