Primary Features

Simulation mechanism

  • Hybrid calculation method combining ray-tracing from both light source and view point to reproduce behavior of light in 3D space
  • Progressive processing allowing the user to show results gradually and to suspend the calculation to be resumed later


  • Interfaces to external CAD system via popular file formats, such as IGES and STEP, to build simulation models based on existing CAD data
  • Arbitrary luminous intensity distribution assignable to illuminants for simulation based on real measured radiation characteristics
  • Reproduced skylight/daylight at any geographic location on the earth by specifying latitude, longitude, date and time
  • Reflectance and transmittance varying depending on angle of light incidence and emitting direction (BRDF/BTDF)
  • Scattering in media or volume scattering definable through the size, concentration and optical properties of microparticles embedded in medium
  • Forming a huge number of micro shapes (e.g. micro lenses) on surface, varying size and/or density independently for each micro shape

Presentation of results

  • Inquiry of simulation results as physical value, such as luminance, illuminance and luminous intensity
  • Visualization of light emitted from light sources for understanding light propagation in a 3-dimensional space
  • Advanced image generation capability allowing high-quality reproduction of object appearance under specific illumination conditions
  • Image-based Lighting allowing objects to be simulated as if they are placed in a real-world environment or under a certain illumination conditions
  • Shadows and reflections reproducible even when a 3-dimensional space is rendered by OpenGL® hardware


  • Distributed processing with multiple network-connected computers in addition to the parallel processing with multiple CPU cores
  • Ability to define emission distribution of light sources using ray data obtained from the near-field photometric measurement
  • Material and light source properties definable independently for each wavelength to present results of the calculation for each wavelength
  • High-precision BRDF/BTDF measurement service available for users
