Technical documentation for the DNA Visualizer coursework project. For a quick start, see the main README.

Contents

Document	Description
Architecture	High-level design, module boundaries, and main loop
Rendering pipeline	FBO, Phong shading, post-processing (Sobel, FXAA, vignette)
DNA model	Sequences, helix geometry, Watson–Crick pairing, mutations
Module reference	Classes, responsibilities, and key APIs
Build & development	Build steps, dependencies, conventions, extending the project

Quick reference

Application loop
  poll events → update (input, animation, mutations) → render scene to FBO
  → post-process → ImGui overlay → swap buffers

Entry point: src/core/main.cpp → dna::Application::run()

Asset paths: Shaders and textures are loaded relative to the working directory (assets/). Always launch the executable from the repository root.
