infiniteway / ray-tracer

A CPU-based Monte Carlo ray tracer using photon mapping. Implemented in C++.

Description

A Monte Carlo ray tracer implementation using photon mapping.

Currently supports:

• Intransparent materials using Oren-Nayar and Lambertian BRDFs.
• Transparent and reflective materials.
• Shadow, indirect and direct photons.
• Parallelized/multi-threaded rendering using OMP.
• Caustic photons.

TODO:

• Optimized ray casting using an octree and AABBs.

A few troubleshooting tips

• IMPORTANT: Use the 32-bit binaries (build using x86!). Otherwise GLM might bug out.

• OPTIONAL: Linker -> Command Line -> Add "/NODEFAULTLIB:MSVCRT /NODEFAULTLIB:LIBCMT"

• OPTIONAL: Remove warning LNK4099:

  • Change C/C++ -> Output Files -> Program Database File to: "$(TargetDir)$(TargetName).pdb"

  • Change Linker -> Debugging -> Generate Program Database File to: "$(TargetDir)$(TargetName).pdb"

• OPTIONAL: Adding /FORCE:MULTIPLE to the Linker command line helps remove errors LNK1169 and LNK2005.
