What is 3DOptix?

The fastest, most intuitive, non-sequential, ray tracing, cloud-based, optical system simulation software.

​ 3DOptix’s innovative GPU and cloud-based ray tracing engine can trace billions of rays per second, faster than any other simulation software on the market. ​ Our easy-to-use application enables you to easily design both simple and complex optical systems and make smart decisions based on real data. ​ 3DOptix Warehouse is the first ever cloud-based workspace for sharing optical designs. With numerous designs available, the 3DOptix Warehouse offers engineers an unparalleled resource for exploring new ideas, discovering innovative solutions, and finding great starting points for their own designs. ​ ​

API Python Wrapper

​ Our API python wrapper is released in a beta version and has only limited features support at the moment. We are working on supporting more features and you can expect new versions to come out soon.​ ​

Features

​ ​The API contains the following abilities: ​

• Get information about your current setups.

• Choose setup to work on.

• Change position and rotation of simulation parts.

• Run simulations on the cloud. ​

  And it has the following logic and terminology: ​

• Get: Used to get the basic information about the element (setup, part, etc), such as id and name.

• Fetch: Used to request deeper information about the chosen element, such as setup's parts or part's position and rotation.

• Update: Used to push changes that were made locally to 3DOptix systems.

• Run: Used to execute simulations on 3DOptix systems. ​

Installation

​ API python wrapper installation is available using PyPi: ​

pip install threed-optix

​ Get your API key from 3DOptix user interface (under "user settings"): ​

Begin

​ The API consists of: ​ ​

• ThreedOptixAPI object, that communicates with our server.
• Setup object, that contains information about a simulation setup.
• Part object, that holds the information about a setup part.
• AnalysisResult object, which handles the simulation results data.
• Vector3 object, which allows to transform and rotate the parts.

Import and authenticate:

import threed-optix as tdo
​
#Your API key from 3DOptix user interface
api_key = '<your_api_key>'
​
#api is the object that manages the communication with 3DOptix server

api = tdo.ThreedOptixAPI(api_key)

Get a list of your 3DOptix setups:

#'setups' will be a list of your simulation setups, each one has a name and id
setups = api.get_setups()

Choose the simulation setup you want to work on:

#Chosen setup name
setup_name = '<your setup name>'
​

#Get the 'tdo.Setup' object to work on
setup = None
for s in setups:
​
    #Pay attention that setup name is not unique, and id is.
    print(s.name, s.id)
​
    #Get your setup by name
    if s.name == setup_name:
        setup = s​
        break
​
assert setup is not None, "Setup was not found"
​
# Fetch setup parts and information
# The method updates the setup object parts
api.fetch_setup(setup)

Change Simulation Setups

​ We can change the properties of setup parts. ​ At the moment, we support changing the position and rotation of parts. ​ We can identify each part with its id and label properties. ​

Access setup parts:

# 'parts' will be a list of the elements in the setup
parts = setup.get_parts()

Choose the part that you want to modify:

#Chosen part id
part_id = '<the id of the part to change'

#Get the 'tdo.Part' object to work on
part = None
for p in parts:
​
    #Pay attention that the part name is not unique, and id is.
    print(p.label, p.id)
​
    #Get part by id
    if p.id == part_id:
       part = p
       break
​
assert part is not None, "Part was not found"
​
#Fetch the part data
# The methods update the part object position and rotation
api.fetch(part)
​
#Before you make any changes, we recommend to import copy and store the original part with deepcopy:
original_part = copy.deepcopy(part)

Change Rotation

​ Each part has a part.change_rotation method, which enables to change the rotation with respect to the x, y, and z axis, using tdo.Vector3 object. Rotation is stated using degrees. ​

#Define the rotation
new_rotation = tdo.Vector3(90, 0, 45)
​
#Apply on the part
part.change_rotation(new_rotation)

Change Position

​ Each part has a part.change_position method, which enables to change the part x, y, and z locations relative to their primary coordinate system, using tdo.Vector3 object. Position change is stated in mm. ​

#Define changes
new_position = tdo.Vector3(1, 0.5, 3)
​
#Apply on the part
part.change_position(new_position)

Update Part

​ In order to update the local changes to the original setup in the 3DOptix interface, we need to use api.update method: ​ ​

#Update the changes
api.update(part)
​
#Since we stored the original part, we could always restore it
api.update(original_part)

Run Simulations And Analyse

​ Running the simulation on the cloud is really simple:

#run the simulation
result = api.run(setup)
​
#fetch the data
api.fetch(result)
