Blender是一個免費且開源的3D創作軟體，在藝術家、設計師和開發者中非常受歡迎。由Blender Foundation開發，提供了一套完整的工具，用於創建驚人的3D動畫、模型和視覺效果。

Blender 的使用者介面設計直觀且友好，使初學者和專業人士都能輕鬆使用。它提供了廣泛的功能，包括建模、雕刻、材質編輯、燈光、動畫和影片編輯。該軟體還支援第三方插件，這使得靈活性和自定義性更高。

Blender 的社群也是一項重要的資產。有許多在線資源可供學習如何使用 Blender，包括視頻教程、文件和論壇。此外，社群經常製作可供免費下載和使用的附加組件、資源和插件。

Blender有廣泛的應用範圍。它通常用於為遊戲、電影和電視節目創建3D模型。建築師和室內設計師也常使用它來創建建築和空間的逼真視覺效果。此外，Blender經常被藝術家和設計師用於創造抽象或風格化的藝術作品。

Blender 是一個多功能且強大的工具，適合對3D建模、動畫或視覺效果感興趣的任何人。它的可及性和強大的功能集使其成為初學者和專業人士的絕佳選擇，而且其活躍的社群確保總有新的東西可學習或探索。

Version 2.70

Cycles Rendering
Cycles now has initial support for volume rendering including emission, absorption and scattering. Volume rendering can be used to render effects like fire, smoke, mist, absorption in glass, and many other effects that can't be represented by surface meshes alone.
CPU rendering performance was improved, particularly for hair, textures and Open Shading Language.

Motion Tracker
Trackers can now be weighted, to keep the result stable as feature disappear or become difficult to track. The plane track workflow was improved to be easier to control. Automatic feature detection was made more robust using a new detector algorithm.

User Interface
The toolbar now has tabs to organize tools in categories. Multiple buttons can now be edited at once, for example for XYZ axes or color channels. Transform tools now have a mode to enter expressions and units. Other changes were done to improve lists, header menus, tooltips, buttons, menus and more.

Modeling
The Laplacian Deform modifier was added to pose a mesh while preserving geometric details of the surface, and a new wireframe modifier allows you transform your mesh into a wireframe representation. The boolean modifier now supports ngons, and there are improvements to the bevel, screw and triangulate modifiers.
The bevel tool now offers more control over the bevel profile and results, and the knife tool was improved as well.

Threaded Dependency Graph
An important change that happened under the hood is the threaded dependency graph. This means that object modifiers and constraints, among other things, can now be computed with multiple threads taking advantage of multicore processors. This will be most noticeable with scenes that have many objects, or multiple objects with heavy modifiers. This is the first step in making the dependency graph in Blender more powerful.

Game Development
The Blender game engine now supports discrete level of detail for meshes. For game developers, support for working with Photoshop PSD files has been added.
A new view navigation walk mode has been added, which has a control scheme as typically found in first person shooter games. This can be useful for game developers to navigate levels as if in a game.

Freestyle NPR Rendering
The Freestyle Python API is an essential part that makes it a highly programmable NPR rendering engine. This API has been reorganized.

More Features
Many small changes and features were done all over Blender. Some notable new feature are normalized display for FCurves, derivative map baking, baking to vertex colors, better visualization of masks and control over mask filling, gravity option for sculpting, negative texture values to support vector displacement and a Lamp Data shading node to create more customized NPR shaders.

Feature Videos

Addons
Several addons have been added and updated, including Node Wrangler (aka Node Efficiency Tools) and a new Sketchfab Exporter addon

Bug Fixes
In addition to the new features, over 560 bugs that existed in previous releases have been fixed.
