A physically based spectral raytracing library

Spectre

A (WIP) physically based spectral raytracing library.

Introduction

Spectre is the successor to Elixir, with emphasis on clean, highly tested code.

Written from the ground up in modern C++ (C++20), Spectre improves upon Elixir in the following areas:

• Code quality improvements - adheres better to SE principles
• Less over-engineered - complexity only when it offers significant advantages
• Test driven development - close to full unit-test coverage
• SIMD acceleration with AVX2
• Physically-based spectral rendering as a foundation

Spectre continues to take inspiration from SORT and PBRT.

Requirements

• Only CMake versions 3.8 and up is supported
• If compiling with GCC, use GCC10 and above

Spectre uses SMath as a submodule. As such, it is necessary to pull submodules when cloning Spectre.
