Python automation API for Earth Volumetric Studio

EVS Automation for Python

Python automation API for Earth Volumetric Studio, a commercial product of C Tech Development Corporation.

This library provides a workflow for controlling EVS from any Python 3 environment. Care has been taken to enable the same functionality as the internal Python API, as well as additional features specifically intended to function from automated workflows.

Features

• Process Management: Start new, or connect to existing EVS processes, and automate actions
• Full EVS Python API: The evs.* Python functions have all been ported, so scripts written inside EVS can be migrated to work via automation with few, minor changes.
• New API Additions: Additional API functions are available, including loading .evs applications, running existing Python scripts, and shutting down EVS

Requirements

• Windows (uses Win32 APIs for communication with EVS)
• Python 3.12+
• Earth Volumetric Studio 2026.3+

Installation

pip install evs-automation

Dependencies (pywin32, psutil, packaging) are installed automatically.

Quick Start

import evs_automation

try:
    # Launch a new EVS process
    with evs_automation.start_new() as evs:
        # Load an application
        evs.load_application('C:\\Projects\\my application.evs')

        # Note that the syntax below is identical to the internal EVS Python script syntax

        # Instance a titles module and set the title
        newmodule = evs.instance_module('titles', 'titles', 363, 679)
        evs.connect(newmodule, 'Output Object', 'viewer', 'Objects')
        evs.set_module(newmodule, 'Properties', 'Title', 'Title added from script')
        evs.set_module(newmodule, 'Positioning', 'Anchor Side', 0)

        # Execute a Python script
        evs.execute_python_script('C:\\Projects\\export_data.py')

        # EVS (by default) will shut down at this point automatically
except Exception as e:
    print(f"Received exception: {e}")
