Format Converter

Overview

Convert between 360° image projection formats without AI processing. GPU-accelerated mathematical remapping — instant results, no model download required.

Supported Formats

Input Formats

• Equirectangular — Standard 2:1 360° format (most common)
• Fulldome (Domemaster) — Circular fisheye for planetarium domes
• Fulldome Angular — Angular fisheye variant
• Cubemap Cross — 6-face cube unfolded into a cross layout

Output Formats

• Equirectangular — Universal 360° interchange format
• Fulldome (Domemaster) — For planetarium projection
• Fulldome Angular — Angular fisheye variant
• Cubemap Cross — For game engines, VR applications
• Rectilinear — Standard flat/perspective view extraction

Conversion Types

Equirectangular ↔ Cubemap

Convert between the standard 360° format and 6-face cubemap layout. Useful for game engine integration (Unity, Unreal, Godot).

Equirectangular ↔ Fulldome

Convert for planetarium dome projection. Supports both standard domemaster and angular fisheye variants.

Rectilinear Extraction

Extract a flat (perspective) view from any direction in a 360° image: - Set field of view angle (how wide the crop) - Set look direction (yaw + pitch) - Output is a standard flat image — use for social media, prints, previews

Usage

1. Navigate to the Format Converter tab
2. Select input format
3. Select output format
4. Upload or select source image
5. Configure parameters (FOV, direction for rectilinear)
6. Preview result
7. Export converted image

Technical Notes

• All conversions route through equirectangular as interchange format
• GPU-accelerated via CuPy CUDA kernels
• Professional-grade quality at any resolution up to 8K
• No AI model required — pure mathematical remapping
• Supports batch conversion via API
