Welcome to BeforeTheMesh
The educational foundation of our ecosystem, teaching the principles behind TheMeshProject and btm‑framework.

What we focus on
  • Clean, scalable C++ project architecture.
  • Modern, target‑based CMake workflows.
  • Rendering engine fundamentals and application layers.
  • Math foundations, mesh loading, and visualization pipelines.
Who this is for
BeforeTheMesh is designed for intermediate developers who already know basic C++ and want to understand how real rendering engines and tools are structured.
What you will build

You will gradually construct:

  • A rendering window and modular application layer.
  • A math module and rendering pipeline.
  • A mesh loader and real‑time visualization tool.
How the tutorials work

Each tutorial:

  • Introduces a concept and the engineering reasoning behind it.
  • Provides clean, modern C++ code integrated with btm‑framework.
  • Ends with a working result—no hidden magic.
Your first step

Start with Step 1: Setting Up Your Environment , where we present the initial setup. You will install the tools, build the framework and the examples, and run our first applications to verify that everything is working correctly.
