Lightmetrica : A research-oriented renderer

Introduction

Lightmetrica is a research-oriented renderer mainly for implementing various rendering algorithms. Implementation is written for easy understanding, and easy to profile the performance of the algorithms. All applications are written in C++ language with C++11 standard, and are executable in Windows or Linux environment. Implemented algorithms are written so that users can grasp the relationship between the implementation and the formulation in the original paper.

Features

• Implements various types of global illumination techniques
• Moderately unit tested
• Includes fast SIMD-based math library
• Various options for floating-point precisions (single, double, multi-precision)
• Clean and generalized design according to Veach's formulation
• Clean and easy-to-read log output
• Experiments support
• Plugin support

Dependencies

Dependencies which requires additional installation step.
Specially for VS2012 and VS2013 environement in Windows, we offer x64 binaries in the external submodule.

• Boost (1.53.0 or higher)
• Assimp (3.1.1 or higher)
• FreeImage (3.15.4 or higher)

The following dependencies are contained in the source or the external submodule, so you don't need special setup for them.

• Google test (1.7.0 or higher)
• Pugixml (1.2 or higher)
• SIMD-oriented Fast Mersenne Twister (SFMT) (1.4.1 or higher)

Implementation detail

This software contains the following projects:

• Core libraries
  • liblightmetrica : The main library in which various rendering algorithms are implemented. The project is configured to compiled by the dynamic library (*.so in Linux, *.dll in Windows). The library is shared by the following projects.
  • liblightmetrica.test : Static library for unit testing.
• Applications
  • lightmetrica : The command line renderer interface.
  • lightmetrica.gui : The GUI renderer interface. Yet to be implemented.
• Tests
  • lightmetrica.test : Unit test project for liblightmetrica.
  • lightmetrica.perf : Performance test project for liblightmetrica. Yet to be implemented.
• Plugins
  • plugin.test : An example plugin
