A simple cross-platform C++17 library for developing computational 3D graphics applications.

Features

• 3D mesh IO, manipulation, hardware and software rendering.
• Imaging IO, manipulation
• Linear algebra with solvers
• Ultra-simple declarative GUI (currently only implemented for Windows)
• Cross platform build file construction tool.
• Command-line interface tools with pretty-print.
• Unicode, filesystem, diagnostics, data packaging, etc.
• Support for VS2019,2022 on Win, gcc & clang on Ubuntu and MacOS. Warning-free compiles on -Wall.

Design

• Emphasis on clear, correct code rather than premature optimization.
• Functional and declarative design in as much as makes sense for C++.
  • Extensive use of return value elision.
  • Declarative GUI layout, declarative dataflow graph for computations.
• Minimal OOP-fuscation; Some member functions and constructors, few private members, no impl inheritance.
• Templates are used when they provide clear benefit; Avoid complex template metaprogramming.
• Exceptions and RAII used throughout.
• Compiles out of the box; No dependencies, install scripts or special make packages required.
• Different compiler / configuration object files are kept in different directories for fast switching.
• Conventions: camelCase, K&R brackets, why-not-what comments.
• namespace Fg { varNoun, funcVerb, cNoun short for calcNoun, StructName, FG_MACRO }
• Less code is better code
