Maxwell Render is a software package that aids in the production of photorealistic images from computer 3D model data. It was introduced as an early alpha on December 2004 (after 2 years of internal development) and it utilized a global illumination algorithm based on a metropolis light transport variation. Maxwell Render was among the first widely available implementations of unbiased rendering and its GI algorithm was linked directly to a physical camera paradigm to provide a simplified rendering experience wherein the user was not required to laboriously adjust illumination parameter settings, as was typical of scanline renderers and raytracers of the time. Maxwell Render was originally developed by Madrid-based Next Limit Technologies, which was founded in 1998 by engineers Victor Gonzalez and Ignacio Vargas. Maxwell Render is software for rendering only, meaning that other software must be used to create 3D models.
