PBRTParser

A parser written to convert scene from pbrt (v3) format to yocto format (obj).

How to use

Once compiled using cmake, run

parse <file_to_parse> <output_obj>

TODO

In order of importance

  • Mix material: texture blending might have some transparency problem (check landscape/view-0 as an example).
  • Colors in ecosys scene are a bit different.
  • Shapes material's properties overriding and overall testing of materials.
  • Checkerboard texture produce different colors (maybe related to solved env map problem).
  • [pavilion-night] check the transparency issue of the left part of image, check why lights are much stronger than pbrt rendering.
  • Test illumination, implement some hack for distant light.
  • Uber material has index property that will use to create a constant texture for "eta" (seen in code)

Rendering examples

You can find some rendering examples in the folder "images"-

Credits
