Learning from Deployment Experiencete application written in C. Functions defined by an “embedding” program may be called via Python script, running on the embedded interpreter. As such, Blender itself embeds a Python interpreter, providing access to some of its own functions. Python-callable functions must be registered using the Py

r the . module. Even when discussing support code, it is impossible to delineate these modules as entirely autonomous subsystems. We have tried to approximate this, at times avoiding dependencies and some Blender codebase paradigms. Now, in this chapter, we cover the . module. More specifically, we

vide a platform for adding a simple button layout using Blender’s custom user interface (UI) API. Along the way, we will encounter the . module, an abstraction layer for Blender’s underlying hardware-based rendering API (i.e., OpenGL). We will also register a few non-modal operators for our editor.

,Intro to the “Core” Blender Source Code,der’s codebase is written primarily in the C programming language. Part of this introduction is a preliminary discussion of Blender’s CMake build system. Additionally, we provide an execution trace of how Blender registers an operator, and of the execution of its callback. Much of this book will be

,Blender “DNA” and Serialization, the most interesting aspects about the blend file is that it has been engineered to be very fast. Its contents are a binary image of memory, when the file was serialized. Blender supports backward compatibility, making the required transformations of the data structures in a given release to any la

Importantly, Blender is also an OpenGL program. We outline the required steps client programs must undertake to obtain a platform-specific window, along with a
