IES Parser and Renderer

Overview

A module designed to parse photometric data from IES files and render corresponding light patterns. It aims to assist designers and engineers in visualizing and analyzing lighting specifications in a 3D environment.

Features

• IES Parsing: Seamlessly reads IES files, extracting and structuring data into an accessible IESData namedtuple It handles handles horizontal and vertical angles along with their corresponding Candela values.
• IES Render: Generate preview images of lights positioned at mutable distances against a wall. Render is returned as PIL.Image instances, with options to save directly.

Getting Started

Prerequisites

• Python 3.9+
• Pillow 10.0.1
• PySide2/6 or PyQt4/5
• QtPy 2.4.0

Installation

Provide clear steps about how to install and set up your project.

git clone https://github.com/michaellevin/ies-render.git

Usage

import IES_Thumbnail_Generator
image = IES_Thumbnail_Generator('path/to/light.ies').render(
            size=512,
            horizontal_angle=0.0,
            distance=0.0,
            blur_radius=1.0,
            save=True,
            out_path='path/to/light.jpg',
        )
# Return a PIL.Image instance
