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

The Format Converter is a processor selected in the Diffusion tab's pipeline dropdown — not a separate tab. Select format_converter from the pipeline list.

Single Image

1. In the Diffusion tab, choose Format Converter from the pipeline dropdown
2. In the Input tab, upload or select your source image
3. In the Output tab, choose your desired output format
4. Start processing — the conversion runs instantly

Batch Conversion

Use the batch convert component to process multiple images at once: 1. Select the Format Converter pipeline 2. Switch to batch mode in the Input tab 3. Add multiple images to the batch queue 4. Configure output format and destination 5. Start batch processing — all images convert in sequence

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
• 0 GB VRAM required (no AI model loaded)
