Blender 3D Models
These have .blend file format.
.BLEND – a 3D image or animation project created in Blender, an open 3D modeling program. Contains 3D grid data, lighting information, vertices, animation keyboard, NURBS objects, texture, uvmapping markup and real-time interactivity data. Can store different scenes in a separate file.
The blender files contain all the objects, texture, sounds, images, effects and scenes used in the animation. But the BLEND file format is a project file, not the basic 3D image or animation.
Blender is professional free and open source software for creating 3D computer graphics that includes modeling, animation, rendering, post-processing and video editing with sound, compositing with Node Compositing, and creating interactive games. Currently have the biggest popularity among free 3D editors due to its stable and rapid development, which is promoted by a professional development team.
A main feature of the Blender software is its small size comparing to other popular 3D modeling packages.
- Support for a variety of geometric primitives, including polygonal models, a quick modeling system in subdivision surface (SubSurf) mode, Bezier curves, NURBS surfaces, metaballs (metaspheres), sculptural modeling and vector fonts.
- Universal built-in rendering engines and integration with external renderer YafRay, LuxRender and many others.
- Animation tools, including inverse kinematics, skeletal animation and grid deformation, keyframe animation, nonlinear animation, editing of vertex weighting factors, constraints, dynamics of soft bodies (including the definition of collisions of objects in interaction), dynamics of solids based on the Bullet physics engine and a particle-based hair system.
- Python is used as a tool for creating tools and prototypes, a system of logic in games, as a means of importing / exporting files (for example, COLLADA), automating tasks.
- Basic functions of nonlinear editing and video combining.
- Blender Game Engine is a sub-project of Blender that provides interactive functions, such as collision detection, dynamics engine and programmable logic. It also allows you to create separate real-time applications from architectural visualization to video games.
Blender had a reputation for being difficult to learn. Almost every function has a corresponding key combination, and given the number of features provided by Blender, each key is included in more than one shortcut. Since Blender became an open source project, full context menus have been added to all functions, and the use of tools is made more logical and flexible. It also has the user interface with the introduction of color schemes, transparent floating elements, a new system of viewing the object tree and various minor changes.
- In the Blender software the entity interaction with the outside world and its data (the form or functions of the object) is shared. The Object-Data relationship is represented by a ratio of 1: n
- An internal file system that allows you to store multiple scenes in a single file (called a .blend file).
- All “.blend” files are compatible with older and newer versions of Blender. Also they are all portable from one platform to another and can be used as a means of transferring previously created works.
- Blender makes backup copies of projects during the entire operation of the program, which allows you to save data in case of unforeseen circumstances.
- All scenes, objects, materials, textures, sounds, images, post-production-effects can be saved into a single “.blend” file.
- The settings of the working environment can be saved to a “.blend” file, so that when the file is downloaded, the user will receive exactly what is stored in it. The file can be saved as “user-defined by default”, and each time Blender starts, the required set of objects and the prepared interface will be output.
