Pyaccelerad

Pyaccelerad is a Python interface for Accelerad, designed to mimic the API of Pyradiance.

It wraps the Accelerad binaries (accelerad_rpict, accelerad_rtrace, etc.) allowing you to call them from Python.

Installation

pip install .

Requirements

Accelerad Binaries: You must have Accelerad installed. By default, Pyaccelerad looks for binaries in: C:\Program Files\Accelerad\bin

You can override this by setting the ACCELERAD_BIN environment variable to your Accelerad bin directory.

Usage

import pyaccelerad as pa

# Call accelerad_rpict
# Arguments are passed as flags.
# e.g. -ab 5 becomes ab=5
# Positional arguments are passed as a list.

# Example: accelerad_rpict -ab 5 -vf view.vf scene.oct
output_image_data = pa.rpict("scene.oct", ab=5, vf="view.vf")

# You can write the output to a file
with open("output.hdr", "wb") as f:
    f.write(output_image_data)

Mapped Functions

The following functions are mapped to their Accelerad counterparts:

• rpict -> accelerad_rpict
• rtrace -> accelerad_rtrace
• rcontrib -> accelerad_rcontrib
• rfluxmtx -> accelerad_rfluxmtx
• genBSDF -> accelerad_genBSDF

Notes on Binaries

Accelerad binaries are compiled against specific CUDA versions. Ensure your installed Accelerad version matches your hardware and drivers. Pyaccelerad does not bundle these binaries; it relies on your local installation.
