Draft: Python bindings using nanobind #8

diiigle · 2023-02-07T17:31:59Z

I started adding python bindings based on the nanobind example.

Supplied bindings:

the high level BSDF class (RGB for now, but can be trivially switched for the spectral version)

Missing bindings:

Warp2D
spectral variants (ideally alongside RGB)

So far this is a quick and dirty job, but if there is interest I can add the missing bits as well.

based on https://github.com/wjakob/nanobind_example

Tested on collab:

# merged PR on this fork:
!git clone https://github.com/soufianekhiat/brdf-loader.git

run:

import sys
!{sys.executable} -m pip install brdf-loader/. -v

Results:
