Luis E. Gamboa, Adrien Gruson, Derek Nowrouzezahrai. In Computer Graphics Forum (Eurographics 2020). [Project page]

Installation

This is a branch of mitsuba 0.6.0 renderer. In this release, we provide the following plugins inside src/devplugins:

• fast_accurate: our method
• multilayered_guo2018: Guo2018 method (project page)
• and all the required supporting plugins to render with both methods.

Scenes

• Coffee table, including the red mug.

Rendering

To render a scene file using our material set and 512 samples per pixel use: mitsuba -D materials=ours -D spp=512 scene.xml

Set materials=guo to render using Guo2018.

To test different integrators, use -D integrator= to:

• pathwsampler: path tracing w/MIS.
• directwsampler: direct illumination w/MIS.
• directlightsampling: direct illumination using only Light Sampling.
