constexpr_raycaster's Introduction

Description

This is an experiment in compile-time eval on c++-14 and above. Test constitutes the computation of an image via raycasting over a minimalistic scene of voxels. The practical value of this project is nil, aside for torturing the compiler.

Test passes successfully on:

compiler, RAM amount
g++-6.3.0, 8GB RAM
g++-7.4.0, 6GB RAM, 14GB swap
g++-8.1.0, 16GB RAM
g++-8.2.0, 4GB ZRAM
g++-8.3.0, 4GB ZRAM
g++-9.1.0, unknown (godbolt.org); output reduced to 128x128
g++-9.2.0, unknown (godbolt.org); output reduced to 128x128

Test fails for various reasons on other compilers. Such as:

  • not-constexpr pure functions in cmath
  • not-fully-c++14-compliant constexpr support
  • compiler runs out of (virtual) memory
