A Spectral Viewer :

spectral viewer logo

Main features are:

  • Open Spectral images defined by the Harris Geospatial ENVI file format
  • Spectrum visualisation per pixel or for a controlable kernel size
  • Screenshots saving in HDR or LDR mode
  • Different kind of Zooms

Source code and binary packages are available on Spectral Viewer's main web site.

Malia Rendering Framework aka MRF

HAVE A LOOK AT THE NEW MRF 3 hosted on INRIA gitlab .

Caveat : MRF 3 is still under development but you can already test it and use it from Blender or on the command line

mrf-rendering-example MRF V3 is based on the MRF V2, which is a rendering Framework I started during my PhD and has received contributions from Xavier Granier, Mickaël Raynaud and Vincent Lebret-Soler. A subset of MRF is available when downloading the source code from HDRSee. Almost all images on this website our publications come from rendering application built with MRF V2 or V3. MRF main features are:

  • HDR image management with some Tone Mapping operators implemented. HDR images are stored without any compression scheme but can be exported to .hdr or .exr format using FreeImage or OpenEXR libraries.
  • Ray-Tracing and Path-Tracing systems as well has Particle-Tracing.
  • Uniform Grid as accelerating structure
  • GPU : high-level C++ classes to manage texture objects, framebuffer objects, vertex buffer objects, shaders and other recent OpenGL extensions like Bindable Uniform.
  • Area, directional, point light sources are supported as well as the one generated by HDRShop. Environment map are transformed into directional light sources.
  • Material support : Lambertian, Physically correct Phong BRDF as proposed by Lafortune, Ashikhmin & Shirley BRDF. The Aliaswavefront.mtl format is also supported.
  • Geometry : a lot (too much) of classes to manage meshes with or without attributes per face or per vertex. Normal maps are also supported. We have also implemented a kind of progressive mesh used for distributed rendering. OBJ, PLY and 3DS formats are supported to describe the geometry of the scene.
  • Software implementation of G-Buffer technique
  • XML file format for scene and camera
  • Maya-plugin to export the camera parameters to a file

ALTA Library

alta-logo ALTA a general-purpose C++ Library to analyze BRDF models and measurements.

MHDRViewer (aka HDRSee)

MHDRViewer has now its own website on INRIA GForge.

hdrsee-logo MHDRViewer is a GPU-based LDR/HDR image viewer that implements different kind of tone-mapping operator and that aims, through a pluging mechanism, to be easily extended by developpers.

MHDRViewer functionalities are:

  • All Graphics Image format supported by FreeImage
  • Screenshots
  • Different kind of Zooms
  • Command line mode for batch mode use

Known Limitations

  • Maximum Image size supported: 8K (this is due to OpenGL 2 limitations)
