C++ Ecosystem in Windows and Linux for Graphics Programming

Due to the faster computation, C++ is still (2026) the best choice for real-time rendering and Python is far behind in this real-time performance race. C++ is a powerful language with different excellent features, some are the latest version-dependent as well. Nonetheless, over the years, I have noticed, some of the commonly used C++ features used in graphics rendering are, Pointer and References (the smart pointer might be helpful to reduce data leak), STL, Type Casting, Vecot and Matrix Operations, etc. These are some of the frequently used features.

Someone working (or interested working in Graphics Rendering) may already have profound knowledge of the language. Besides, I might recommend some of the excellent learning resources, viz. Learncpp, CPP Reference, MS C++ documentation, MS C++ Blog, CppCoreGuidelines, cpp different versions’ features cheatsheets, isocpp, cppcon, helped me understanding the language. However, learning by actually coding is the best way in my opinion. There are several git projects for C++, e.g., Bjarne Stroustrup’s Github repository, 30-seconds-of-cpp, cppbestpractices, project-based-learning.

Naming convention for a C++ project may vary company to company, even among different developers’ team. The google C++ style guide is a popular choice. Besides, someone can check C++ Best Practice, similar to Boost Style and C++ Coding standard. The Hungarian Notation was once a popular choice as well.

Documentation is essential for understanding the gist of the code in the quickest possible time. Unfortunately, in my experience, this is the part where the development team often pay the least attention. Doxygen is being used for long time for documentation purposes.

Probably, Rust (👍🏽), Lua, Nim, Zig, C3, Golang/Go, Dart, Carbon could be name as the Successors of C++ language.

At the time of writing this (October, 2025), there are limited publicly available rendering engine that works for real-time stereo path tracing. The slow convergence with pixel dense display in VR is limiting real-time stereo path tracer. However, with the RT-core and GPU architecture improvements, I am noticing the recent trend of physically accurate light simulation in real-time rendering, e.g., games. Therefore, definitely with time, the real-time stereo path-tracing (and with other advanced global illumination algorithms) would be a real thing once we will overcome frame-rate constraint. Physically-accurate light simulation will minimized the difference between real and virtual world and extend the path of true immersion. Currently, 90 fps has become a golden standard for VR. However, the higher is the better for immersion.

Tamashii is an excellent scientific rendering framework under development by the Department of Computer Graphics, TU Wien. Its main goal is to simplify the creation of research applications in the field of computer graphics by providing a fundamental structure in the form of libraries implementing resource loading, input handling, user interface creation, a complete rendering framework, and graphics API abstraction. The backend graphics API is Vulkan. However, Tamashii only supports single display systems, and \textbf{has not been modified for VR.}
