<!-- SECTION: Summary -->
## What is Harmonikr?

Harmonikr is a developer utility designed to compute spherical harmonics and irradiance from environment maps for real-time rendering applications. It supports HDR workflows and allows developers to store computed data as 2D maps for efficient shader sampling.

<!-- SECTION: Key Features -->
## Key Features

- **Harmonic and Irradiance Computation**: Calculates arbitrary numbers of spherical harmonics and irradiance from HDR environment maps.
- **Data Export for Shaders**: Stores computed harmonics or irradiance as 2D maps to enable fast sampling within custom shaders.
- **Flexible Format Support**: Imports and exports side-cross cubemaps and equirectangular maps with HDR support.
- **Project Management**: Allows users to save project files containing source images and specific configuration settings.

<!-- SECTION: Target Audience -->
## Who is it for?

Graphics engineers and technical artists working on lighting and environment mapping for custom shaders.
