Lighting Design Calculation Engine

Cerise365™ offers numerous new features including:

  • Improved Radiosity Calculations

Cerise365™  utilizes a proprietary parallel processing algorithm that results in radiosity calculations being two to three times faster than our legacy Helios32/64 software, with extremely large environments with millions of elements being the fastest.

  • JSON

Cerise365™ utilizes a single JSON file. Otherwise, the Cerise365™  API is fully backward-compatible with our legacy  Helios32/64 Version 8.0 API.

  • OpenGL Buffers

Cerise365™ supports both OpenGL 2.1 display lists and OpenGL 3.1 buffers.

  • Real-Time Lighting

Cerise365™ integrates Mandato (Cerise365+Mandato) real-time dynamic lighting into its OpenGL display.

  • Texture Maps

Cerise365™ directly imports JPEG, PNG, BMP, and PSD image files.

  • IES TM-33 Files

Cerise365™ will natively import IES TM-33 and UNI 11733 luminaire optical data files.

  • glTF Files

Cerise365™ exports industry-standard glTF files.

  • Optical Sensors

Cerise365™  supports photometers, radiometers, and PAR (quantum) meters.

  • Fixed Meters

Cerise365™ supports fixed meter arrays with user-specified positions for electric lighting.
