Building etx-tracer

This description will be updated during the development process.

Requirements

Most of external libraries will be located directly in the source code, to reduce a number of dependencies and make building faster. But this libraries and tools you have to install by yourself:

  • CMake
  • Intel Embree for CPU ray-tracing
  • CUDA
  • OptiX
  • optionally OpenVDB if you want to load .vdb files with volumetric data.

Building for Windows

Windows is the only one platform, which is supported at the moment.

  • download and install the latest release of Intel Embree from GitHub
  • copy embree binaries (embree3.dll and tbb12.dll) to "bin" folder in the root directory of etx-tracer;
  • and then building should be as simple as creating a folder for build files and calling CMake, something like:
cmake -G "Visual Studio 17 2022"  ..

Built-in dependencies

These libraries are included into the source code in thirdparty folder:

  • enkits - A permissively licensed C and C++ Task Scheduler for creating parallel programs
  • glm - OpenGL Mathematics
  • imgui - Dear ImGui: Bloat-free Graphical User interface for C++ with minimal dependencies
  • jansson - C library for encoding, decoding and manipulating JSON data
  • mikktspace - A common standard for tangent space used in baking tools to produce normal maps.
  • sokol_app, sokol_gfx, sokol_imgui - minimal cross-platform standalone C headers
  • stb_image - stb single-file public domain libraries for C/C++
  • tinyexr - Tiny OpenEXR image loader/saver library
  • tinyobjloader - Tiny but powerful single file wavefront obj loader
