Learn the essential source code of Blender and its unique build system. This book provides the inner workings of the Blender C-based source code, and will be indispensable for those wanting to contribute to this important open-source project.Blender is an open-source 3D modeling and rendering software package used in the production of assets for animated projects, 3D printing, games, and even scientific visualization. This book goes in depth and discusses the primary modules related to the GUI and the geometric modeling work. You'll start by learning how to reverse engineer geometric operators, and from there move on to the main features of the source code and how to apply them. When done, you'll have the necessary foundation for exploration in other modules of the Blender source code.
Lack of software engineering knowledge, such as experience with large cross-platform code base, remains insurmountable for many new developers. While the Blender site includes much useful information, it is not detailed enough. Core Blender Development breaks down the barriers to entry for open-source development in 3-D modeling.
What You'll Learn
- Find the code for various functions and editors in Blender
- Track down bugs, and contribute new functionality to the Blender code base
- Examine the .blend file and how it stores Blender state
- Understand the Blender core code base beyond the community website documentation
- Review the explicit code traces and source files of descriptions of the code base
Primarily for novice to intermediate level developers and programmers with an interest in Blender, graphics, and visualization, who likely don't have experience of reverse engineering a large code base.

Chapter 1. A First Encounter with Blender's Source CodeChapter goal: To outline the Blender source tree, and provide an execution trace of how Blender registers geometric manipulation operators, and the execution of a few of the associated callbacks.-The Blender ProjectoDiscusses where Blender source code is hosted and how developers can find help online.-The Blender Source TreeoListing of the modules included in Blender, and what each module does-The Blender CMake Build SystemoHow Blender makes uses of the CMake build system, and how various modules can be included or excluded from a build-Some High-Level Geometric Modelling Tools & Their OperatorsoDiscusses how operators are registered in the C codeoDescribes where primitive creation and geometric editing operators are registered and how to determine their callbacks-The Model-View-Controller Architecture of BlenderoExplains the rationale for the general architecture of Blender and its history-Roadmap for the Remaining BookoWhat is "core" Blender? What this book covers and what it does not coverChapter 2. The Blend File FormatChapter goal: Explains the persistent data model and related data structures of the .blend file-What Does the .blend File Contain?oHigh-level description & purpose of the .blend file-Byte Layout of the .blend File-Backwards Compatibility of the .blend File-Blender DNA and the Data ModeloShows how the contents of the .blend file map to DNA (data structures) and the data model and internal API-The Dependency Graph
Chapter 3. GHOST and the Main Event LoopChapter goal: Dissects the global host module (GHOST) and points out the high-level main event loop in the window manager module-Blender's cross-platform support for multiple windowing and operating systems: gHOSToOverview of the source files in the gHOST module-Trace of the Initialization Routines-GHOST and the Event Loop-Differences Between Linux, MS Windows, and MacOS builds
Chapter 4. BlendLib & UtilitiesChapter goal:

Discusses the suite of functions provided by the internal utilities libraries of Blender-The Math UtilitiesoExplanation of the math utilities used throughout core Blender-The File Utilities-The global context and blendlib
Chapter 5. Blender Embedded Python EngineChapter goal: Describes the connection between Python API and the internal compiled code of the embedded (extended) interpreter-How Python is Embedded in a C ProgramoPreliminaries on embedded Python-How Blender Embeds PythonoUI dependenciesoAssociated source files & important module (externally linked) functionsoStartup and initialization-The Data API & RNA generated code
Chapter 6. Blender User Interface ComponentsChapter goal: Describes the internal graphical user-interface of Blender and how Blender uses OpenGL to draw and manage its custom UI-Internal UI APIoDescribes Windows, Other UI Elements, and Events-How to construct simple UI Elements in C.-Hierarchy of UI Elements.-Trace of Window Updates and Drawing in C code
Chapter 7. BMesh Data Structure and the bmesh ModuleChapter goal: Describes the bmesh data structure and how the associated geometric operators update its data.-BMesh DesignoHow BMesh stores geometry data? vertices edges topology etc.oHow BMesh updates data?oHow BMesh is linked to Python scripting modules via RNA (Data API)?oTrace of a Hypothetical BMesh update with the following operators Bevel Extrude Knife Cut etc.-Associated source code (modules and files) of bmesh-How BMesh is serialized in the .blend file?-Associated DNA structures and BMesh
Chapter 8. Adding a Custom Editor ModuleChapter goal: A details set of steps to add a new module to the Blender code base. Provides both an all C-code implementation of an editor, and then an implementation that uses Python to produce the same GUI components. The parallel views further reinforce the material from Chapters 5 & 6.-A Basic Window in CoAdding operators and buttons in C-Adding Operators and Buttons in PythonoHow these UI elements map to C functions in core Blender-Adding Source Files for a New EditoroCMake additions for proper system build with a new module (editor)
