What Are Panorama Tools and Which Ones Do You Need for 360° Workflows?

Panorama tools are small utilities that handle the non-obvious parts of 360° work: writing the metadata platforms need to recognize a photo as spherical, planning how many rows and frames a scene requires, calculating crop values, and checking how a projection will look. On Rodrigo's Tools, four of them map directly to those jobs: 360° Pano Metadata Gen, GPano Visualizer, 360° Panorama Row Calc, and 360° Panorama Crop Calc. You need the metadata generator and visualizer for publishing, the row calculator before you shoot, and the crop calculator when you edit.

The four panorama tools and what each one solves

360° Panorama Row Calc: plan the capture

Use this when you know your lens and want to avoid guessing at coverage. It helps you work out the row structure of a multi-row panorama — how the scene divides into horizontal bands and how many frames each band needs.

The input is your shooting setup (focal length and the field of view it produces), and the output is a row plan you can follow on set. The expected result is full coverage with deliberate overlap rather than a stitched image with a hole at the zenith or nadir. The common failure here is under-shooting the top and bottom rows, which only becomes visible after stitching.

360° Pano Metadata Gen: make the file spherical

A 360° photo is just a wide image until it carries GPano metadata. This tool generates that metadata block so platforms and viewers know the image is an equirectangular panorama and how it should be projected.

Typical inputs are the image dimensions and the projection details; the output is metadata you attach to the file. The expected result is that a viewer opens the photo as an interactive sphere instead of a stretched strip. The most common failure is missing or partial metadata — the image uploads fine but displays flat, and nothing in the file tells you why.

GPano Visualizer: verify before you publish

This is the check step for the previous tool. It shows you how the GPano metadata is being interpreted, so you can confirm the projection and framing are what you intended.

Use it after generating metadata and before uploading anywhere that matters. If the visualizer shows the wrong orientation or a broken projection, fix the metadata now rather than after a platform has cached a flat version.

360° Panorama Crop Calc: keep the frame valid

Cropping a panorama is where seams and black edges appear. This calculator derives crop values that preserve the equirectangular relationship between width and height.

The input is your source dimensions and intended crop; the output is the crop parameters to apply. The expected result is a tighter frame that still projects correctly. The failure mode is an arbitrary crop that breaks the 2:1 relationship or clips the poles, producing visible seams or black bands in the viewer.

How to choose by task

• Planning a shoot: start with the Row Calc. Decide rows and frames before you leave, because this is the decision that is expensive to fix later.
• Publishing a finished panorama: use the Metadata Gen, then confirm with the GPano Visualizer. Treat these as a pair — generating without verifying is how flat-looking 360° photos happen.
• Editing an existing panorama: use the Crop Calc whenever you change framing, and re-check the result in a viewer afterward.

If you only do one thing, verify metadata with the visualizer on any panorama you publish. It catches the single most common reason a 360° photo fails to display as one.

Where these fit in the wider toolkit

Rodrigo's Tools is a collection of visual calculators for photography, video, and 360° workflows, and the panorama set sits alongside related utilities such as the Map Projection tool and the Equatorial Mount calculator. If your work crosses into general capture planning, the crop factor and exposure calculators on the same page cover the non-panorama side. The site describes the collection as free; no pricing or login requirements are stated in the available material, so confirm access on the page itself before relying on it in a paid workflow.
