Ray Tracer in .NET

Introduction

This implementation is a port of the C++ code contained in the repository at https://github.com/tcbrindle/raytracer.hpp. The main goal of the project is to create an implementation in .NET that is as efficient as possible.

TODO

• Reimplementation
• Blazor project - v1.1,
• Support for multiple cores - v1.1,
• Support for multiple cores in batch mode - v1.2,
• Support for SSE instructions - all coordinates in Vector128 (Vector128{x₀,y₀,z₀,1}) - v2.0,
• Support for AVX instructions - all coordinates in Vector256 - v2.1,
• Support for SSE instructions - single coordinate in Vector128 (Vector128{x₀,x₁,x₂,x₃}) - v3.1,
• Support for AVX instructions - single coordinate in Vector256 - v3.1,
• Improved performance after each release.

Blazor project

Blazor project is now available for the basic ray tracer implementation.
