Python bindings of Ocean™ illumination engine

Ocean™ – Physically accurate material & appearance simulation

Introduction

Ocean™ is a high-end simulation and rendering engine that delivers physically accurate renderings of complex materials—such as glass, coatings, and plastics—under real-world lighting and environmental conditions. It combines spectral measurements, advanced optical simulation, and CAD integration to help engineers, designers, and researchers evaluate appearance and performance before physical prototyping. With the Ocean Python bindings, users can automate simulations, batch process material combinations, customize visualization workflows, and integrate Ocean’s predictive capabilities into their own tools or pipelines.

Installation

Supported platforms

• Linux x86_64 with glibc >= 2.39
• Windows 10/11 x86_64

Python versions supported

• 3.8 to 3.13

Install using pip :

pip install eclatdigital-ocean

Getting started

This code snippet renders a cornellbox scene and dumps result as a png file.

import time
from ocean import abyss, examples

# License and initialization
abyss.Licensing().setDemoMode() # use demo mode (watermarks will be present)
abyss.Licensing().check()

abyss.init()

# Main message handling
def onmessage(msg, type):
    print(msg)

abyss.onMessage(onmessage)

# Create a renderer
renderer = abyss.Renderer()

# stop rendering when samples per pixel reach 50
time_cond = 0 # 0: unlimited
spp_cond = 25

renderer.setHaltCondition(time_cond, spp_cond, abyss.Renderer.halt_cond.stops)

# add a local renderer node (computation is performed on the machine running this script)
# using 4 threads
renderer.setParameter("num_threads", 4)
renderer.addLocalNode()

# Call back triggered when computation ends.
finished=False
def onfinish(raw: abyss.Raw):
    raw.writeAuto("cornellbox.png") # Write results to the drive
    global finished
    finished = True
    
renderer.onFinish(onfinish)

# Start the renderer
# WARNING! This is an asynchronous function
renderer.start(examples["cornellbox"])

# Wait for the rendering to finish
while not finished:
    time.sleep(3)
