Stantz, Ray (Tracer)

Overview

I did Peter Shirley's "Ray Tracing in One Weekend" tutorial, and this repo contains the results.

Here's my final render, which used 500 rays per pixel and a max ray depth of 50 bounces, and took 16 minutes to run across 12 theads on an i7-8700K:

clang-format

I love Go's built-in code formatting (gofmt), and I was excited to see that Visual Studio supports per-project C/C++ code formatting via the open .clang-format. I've added a .clang-format to this project that I've customized into something that I find fairly readable.

Unfortunately, VS ships with an older version of clang-format.exe, and I've made use of newer features that cause the older formatter to fail. Luckily, VS is literally calling a copy of clang-format.exe, and that exe can be swapped for a newer build. Here's how I did it:

• Download the latest LLVM snapshot build for Windows
• Extract the contents of the downloaded installer (you do not need to run the installer to do this)
  • If you have 7-Zip installed with the shell extension
    • Right-click LLVM-<version>-win64.exe
    • Choose the 7-Zip context menu, then Extract to "LLVM-<version>-win64\"
  • Find where Visual Studio has installed clang-format.exe
    • For me, it was in C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\Llvm\8.0.0\bin\
  • rename original clang-format.exe to clang-format.exe.original
  • copy the downloaded clang-format.exe into this folder
